Step 5: Melt the Solder

As the jump ring heats up, the solder will begin to melt and flow into the joint. Keep the torch moving to prevent overheating any one spot. Once the solder has flowed evenly and filled the joint, remove the heat and allow the ring to cool slightly.

Step 6: Quench and Clean

Once the jump ring has cooled to a safe temperature, quench it in a bowl of water to cool it completely. Then, place the ring in a pickle solution to remove any oxidation or flux residue. Leave it in the pickle for a few minutes, then rinse it with water and dry it.

4. Tips for Successful Soldering

Soldering jump rings can be challenging, especially for beginners. Here are some tips to help you achieve the best results:

Practice on Scrap: Before soldering your final piece, practice on scrap jump rings or inexpensive materials. This will help you get a feel for the torch and the solder’s behavior.

Use the Right Solder: Match the solder’s flow temperature to the metal you’re working with. Easy solder melts at a lower temperature, making it ideal for delicate or thin jump rings.

Keep the Joint Tight: Ensure the ends of the jump ring are perfectly aligned and touching before applying solder. A tight joint will create a stronger bond and a cleaner finish.

Avoid Overheating: Overheating can cause the solder to evaporate or the jump ring to melt. Keep the torch moving and apply heat evenly to prevent damage.

Inspect the Joint: After soldering, inspect the joint closely to ensure the solder has flowed evenly and there are no gaps. If necessary, reapply flux and solder to fill any voids.

5. Advanced Techniques and Considerations

Solder Alloys and Solder Paste

The need for soldering

Technological advancement has led to more and more miniaturisation. Millions of electronic components are packed into smaller PCBs (Printed Circuit Boards) leading to innovative televisions and mobile phones. Almost all products being used today, be it cars or rockets, rely on PCBs driving one part or the other.

Micro-components need to be mounted on the PCBs and need to be connected which is achieved through soldering. Any defect in soldering has a spiraling impact on mass-production industries such as those producing mobile phones. The soldering process has become more challenging, as with passing time it has to be accomplished in lesser space available for maneuvering on each PCB. Soldering defects are not uncommon though and need to be minimized. One of the many causes of a default in soldering is the alloy used as solder. 

Classification of alloys used for soldering

The alloys used for soldering can be broadly classified into 2 types: 1) leaded and 2) non-leaded. While leaded soldering is the traditional approach, environmental and health concerns have led to the more recent non-leaded approach. Transition to non-leaded alloys for soldering is taking time and many in the field are still using the traditional approach. But technological advancement has been generating more alloys which match the leaded alloys in performance as closely as possible. Factors affecting the selection of alloys are temperature and application.

Alloy-specific issues with soldering

Non-leaded alloy usage being new, many issues have appeared in applications using it. Technological research is being done to bridge the gap. Some common defects in soldering are: 

Composition: Changes in the composition of the solder alloy occurring due to prolonged heating, solder paste’s properties such as particle size, composition, melting temperature and oxide content, whiskers growing on the surface of solder alloys with high tin content (mostly lead-free solder alloys)

Usage: Cracks appearing due to mechanical and thermal stress caused by inappropriate alloy usage, solder beading error due to Inaccurate deposition of solder paste, tombstone effect caused by unequal amount of solder paste applied, defects caused by solder pads reacting with lead-free alloy with a higher tin content at a higher temperature, solder pads not being sufficiently wetted with the solder alloy

Other causes: Warping due to differing thermal expansion coefficients between the PCB and the component package, voids created due to new material base, different temperature profiles, different types of fluxes, higher surface tension of solder in lead-free soldering, voids due to 2 metals joined with different diffusion coefficients, cracks appearing due to higher temperature in lead-free soldering, 

One best practice to reduce defects is to thoroughly clean the PCB after each soldering cycle.

Common types of alloys used

The most common type is a tin: lead ratio of 60:40 which is easier for cold joints and melts from 361°F/183°C to 374°F/190°C. This is very versatile as it can be applied to many applications with melting requirement within this range. It takes a few seconds to solidify after melting. Eutectic alloys which melt and solidify at the same time are used with a tin:lead ratio of 63:37. It melts at the lowest temperature of 361°F/183°C. The advantage of this alloy is that it melts and solidifies almost instantly. 

Among the non-lead alloys the common ones used are tin/copper and tin/silver. Among the two, tin/copper is more widely used as it costs lesser than the tin/silver. Available ratios are tin:copper of 99.3:0.7 and tin:silver of 96.2:3.8. An alloy of tin:silver:copper of 96.5:3:0.5 is used for applications which need higher melting temperature of 422°F/217°C. An alloy that is easily available and also popular is of tin:silver in the ratio of 95:5 and this is used for audio files which need higher connectivity. This melts from 430°F/221°C to 473°F/245°C

Some solders perform better with the application of flux which is defined as percentage per cross section area of solder wire and is available as 3.3%/2.2%/1.1% flux per cross section area of solder wire. Water soluble flux is also available for specific applications.

Printed Circuit Boards (PCBs) are an integral part of most solutions delivered by MELSS, and MELSS has been providing solutions for Soldering Technology for over two decades. MELSS represents Indium Corporation for their Solder Paste and Solder wires in India

Metals used in wire

Whether you're working on a home remodeling project or trying to figure out how to wire your new home, you may want to learn more about the different types of cables and wires you may come into contact with.

A wire is a device used to conduct electricity from one point to another. A cable is one or more wires placed together and used to transmit electricity from one point to another. And if you're wondering what types of metals are used in electrical wires and cables, we've got you covered.

In this article, we examine the different types of metals that are commonly used in electrical wires and cables. Just keep reading to know more.

copper Copper is the most common metal used in wire and cable. Whether it's a kettle power cable, a stove wire, or a laptop charger, it's probably made of copper. This red-brown metal with atomic number 29 has become the most reliable metal for cables and other wiring.

Copper is a very conductive metal. This means that electricity can easily pass through copper, making it ideal for electrical wires. Copper is also relatively cheap compared to other metals. Compared to gold, which has a higher conductivity and is more expensive, copper is the most cost-effective metal for electrical wiring. This means that copper is essentially the best conductor of electricity while still being affordable and cost-effective.

While copper is great for conducting electricity at a reasonable price, it is also flexible. A flexible metal can be bent, bent and folded to some degree without causing damage to wires, cables and insulation. Copper is also malleable, making it easy to mold and make cables and wires.

Another great advantage of using copper for electrical cables is that copper is also resistant to heat. Heat-resistant wires and cables can withstand a large amount of heat without damage or causing an electrical fire. For this reason, it is much safer to use copper wires and cables compared to other metals. Copper is also recyclable, making it a great green choice for your home.

Copper has become the global standard in wire and cable due to its conductivity, affordability, malleability and thermal resistance.

gold Gold is another common metal in wire and cable. It is usually wrapped around other metal strands because it is a cheap metal to use as the only conductor. Gold has a high conductivity and compared to copper, silver and aluminum, it has a higher electrical conductivity. Copper and other metal wires are usually lightly coated with gold on the connection points for various reasons. The most common are very thin wires, which can sometimes reduce conductivity and capacitance.

Gold is extremely solderable and produces no surface oxides. Gold does not react chemically under normal conditions, which makes it a noble metal. Noble metals are extremely resistant to chemical attacks even at high temperatures. Gold also has excellent corrosion resistance. It is alloyed with small amounts of nickel or cobalt and has good wear resistance.

Gold plating on wires and cables offers durability and flexibility, making this metal a key choice in electrical wires and cables. Gold is also used in home electronic wiring due to its longevity and efficiency. The only downside to using gold is that it is expensive, and you can probably get similar results using copper wire or cable.

silver Silver is one of the most conductive metals known to mankind. Although this metal oxidizes, silver is still an excellent conductor of electricity, which is why you can use it in cables and wires.

Silver offers excellent durability and bends easily to allow for everyday use of power cables. However, silver is a rarer metal, making it an expensive choice for cabling and wiring. The second disadvantage of silver is that it reacts to oxidation much more easily than copper and aluminum, which means that copper and aluminum can withstand environmental effects for a longer period of time.

All wires degrade over time, however, silver's high degradation rate compared to its price and availability can make it a poor choice for wire and cable in many scenarios.

aluminium Like copper, aluminum is the metal most commonly used for wire and cable because of its availability and cost. Aluminum is an excellent conductor of electricity and has been used safely in cables and wires for over 100 years.

Aluminum is durable and flexible, which means it can be easily bent and bent, allowing you to move and mold it as needed. Aluminum wiring is also lightweight, which means it is often used for high voltage lines because the lighter weight reduces the tensile force on the wire and enables the aluminum wire or cable to last longer.

Aluminum is also corrosion resistant. In other words, the lifestyle of an aluminum cable is much higher than that of silver or gold. Aluminum also conducts twice as much per pound of copper wiring. Aluminum is also heat resistant, making it a good choice for wires and cables that run for long periods of time.

Aluminum and copper have been used as conductors for 100 years for various reasons. Approved by the National Electrical Code, they are trusted by the electrical industry and efficient electrical applications for both industrial and residential buildings.

Buy Shildar cable tungsten Tungsten, also known as tungsten, is a less common metal. It is an exceptional refractory metal, meaning it is extremely strong and durable against heat and abrasion. This metal is often used in steel to increase hardness and strength. Tungsten has also been used in wiring because it has the highest melting point of all metals.

کابل لاله زار

Tungsten has been used in wiring for centuries as filaments for lighting, electron tubes and electrodes. Tungsten can be expensive, so it is often only used where no other metal can handle the high temperatures.

02

The Role Of Pretreatment Process

Pretreatment: all processes before plating are called pretreatment, the purpose is to dress the surface of the workpiece, remove the grease, rust, oxide film on the surface of the workpiece, and provide the required electroplating surface for the subsequent deposition of the coating.

03

The Role Of Electroplating Process

Electroplating is getting the required coating on the surface of the workpiece, also is the core process of the electroplating process. The quality of this process directly affects the properties of the coating.

04

The Role Of Post-treatment Process

Post-treatment: after electroplating, the coating is processed to enhance the various properties of the coating, such as corrosion resistance, anti-discoloration ability, solderability, etc.

Benefits Of Metal Electroplating

Different effects can be obtained according to various electrodeposits:

1. Copper plating: Base for improving adhesion and corrosion resistance of electroplating.

2. Nickel plating: For base or appearance, improve corrosion resistance and wear resistance.

3. Gold plating: Improve conductive contact impedance, enhance signal transmission.  

4. Palladium nickel plating: Improve conductive contact impedance, enhance signal transmission, wear resistance higher than gold.

5. Tin plating: Enhance the welding ability, and have a shielding effect on nitriding.

6. Silver plating: Improve conductive contact impedance, enhance signal transmission.  

Benefits Of Metal Electroplating

What is Metal Electroplating？

Electroplating is the method of electrolysis to make metal or alloy deposition on the workpiece surface, in order to form a uniform, dense, good bonding force of the metal layer process.

Electroplating coating is uniform, generally thin, ranging from a few microns to dozens of microns.

Through electroplating, we can obtain decorative protective and various functional surface layers on mechanical products, but also repair wear and processing errors of the workpiece.

A New Generation of Conformal Coatings for Challenging Operating Environments

A New Generation of Conformal Coatings for Challenging Operating Environments

Modern electronic assemblies are increasingly expected to survive hostile operating environments and work reliably in conditions of prolonged high temperatures in the presence of thermal shock and high humidity, and where the assembly may be subject to condensation, corrosive agents or other types of chemical attack. Despite this, weight-saving measures have reduced the robustness – and therefore the protective properties - of enclosures and at the same time, environmental legislation continues to limit the use of those considerably more versatile solvent-based protective materials.To get more news about Progressive cavity pump parts, you can visit brysonpump.com official website. A conformal coating provides that essential secondary line of defence beyond that of the enclosure, so in order to achieve long service life for an assembly deployed in a harsh operating environment, it is useful to consider the common modes of attack and, ultimately, how they may be tackled. When selecting a suitable conformal coating material for harsh environments, the following issues must be addressed: the potential for corrosion and condensing conditions and/or immersion in water, component spacing and tin whisker formation. Corrosion is a complicated, diffusion controlled, electro-chemical process that takes place on an exposed metal surface. Despite the range of potential mechanisms and causes, in the majority of cases, three requirements must be met in order for corrosion to take place: the presence of intrinsically electrochemically dissimilar metals (e.g. Gold/Silver and Nickel/Tin), or the creation of an anode and cathode by application of applied bias; the presence of an ionic species (salts, halides, hydroxides and so on); and the presence of mono-layers of condensed water to dissolve the ionic species, producing an electrolyte solution. Preventing corrosion involves the removal of at least one of these pre-requisite conditions. Choice of metals is limited to those used in the solder and solder finish chemistries (which are dissimilar), and there will always be areas of potential difference due to the nature of an electronic assembly. Cleaning can help remove ionic species, but cannot prevent their re-deposition from the operating environment.

Conformal Coatings help prevent the formation of electrolytic solutions by acting as moisture barriers. All metal surfaces on a PCB need to be sufficiently well coated to prevent exposure to a potentially corrosive environment; even small voids in the coating that expose the metal surface can actually accelerate corrosion under certain environmental conditions. The conformal coating challenge is to achieve an appropriate level of coverage of all exposed metal surfaces across the three-dimensional, complex topography that defines the modern PCB.

In addition to this ‘perfect’ coverage, the coating also needs to provide a barrier against moisture while achieving good adhesion to the substrate to prevent delamination. Once a coating is delaminated, moisture ingress will occur, ultimately producing an electrolytic solution from contact with any pre-existing ionic contamination – another very good reason for thoroughly cleaning the board prior to conformal coating application. Condensation

Where there is a significant level of humidity, certain areas of an assembly may drop below the dew point and water will condense on the PCB surfaces, significantly reducing insulation resistance. While pure water is not a particularly good conductor of electricity, any ionic impurities present on the PCB surface will become solubilised to form a conductive pathway. As well as leading to corrosion as described above, these conditions will severely test the insulation resistance of the coating.

Component spacing

Although air is normally an excellent insulator, it can break down in the presence of an electric field greater than 3kV/mm and become partially conductive. Breakdown voltage in air will depend upon the separation of components populating the PCB. If the potential difference between adjacent components is sufficiently high, a complete electrical breakdown in air will culminate in an electric arc that bridges the entire gap between the components. Conformal coatings provide additional insulation resistance and designers can use them to achieve more compact assemblies by placing components closer together than would otherwise be possible without a coating.

Brazed plate heat exchangers in refrigeration plants

Condensers, evaporators, oil coolers, subcoolers, economizers, etc. in refrigeration units sometimes use plate heat exchangers to achieve related functions. There are semi-welded plate type, fully welded plate type, copper brazed plate type, nickel brazed plate type, etc. in terms of plate heat exchanger. Due to the advantages of small size, high efficiency, light weight and self-cleaning properties, brazed plate heat exchangers are used more and more in refrigeration equipment.

The brazed plate heat exchanger is a new type of high-efficiency heat exchanger made by stacking and brazing a series of metal sheets with a certain corrugated shape. Its basic principle is to form a thin rectangular channel between the metal plates, and different media can exchange heat through the plates. The material of the plate is basically AISI316 stainless steel vacuum-welded with pure copper or nickel filler. Brazed heat exchangers can be divided into different categories of products according to material combination and design pressure. Copper brazed plate heat exchanger is a plate heat exchanger that uses stainless steel sheets and copper foil solder with a purity higher than 99% to form an integrated plate heat exchanger under the high temperature of a vacuum brazing furnace.

When in use, select the appropriate type of board to replace and configure it in the refrigeration system according to the type selection calculation software provided by the manufacturer.

After the heat exchanger is purchased and delivered, first check whether the nameplate is consistent with the purchase requirements. The nameplate generally includes the following contents: model, production license number, design pressure and test pressure, design temperature, heat exchange area, quality, manufacturing date or serial number, etc.

Check the documents attached to the product, including packing list, certificate of conformity, installation drawing, product quality documents (plate test report, pressure test, leak test result report, non-destructive test report, etc.). And keep it. The original documents should be archived, and copies can be kept for on-site use. Check whether the technical parameters such as the heat exchange area of a single plate and the number of plates are consistent with the technical requirements.

Before installation, it is necessary to check the signs of the inlet and outlet of the medium, and understand the applicable refrigerant types. Insulate with insulating material to prevent condensation from condensation.

When connecting to the refrigeration device by welding, it is necessary to use a wet rag to protect the heat exchanger, use nitrogen shielded welding, and use an electrode with a silver content of more than 45% for welding with a weak flame.

Due to the different water quality in various places, it is recommended to install a 60-mesh filter on the water pipe entering the heat exchanger. After installation, perform a leak check together with the entire refrigeration unit. During the transportation and use of the device, the heat exchanger should be well protected to prevent bumps.

What are the Types and Benefits of Oxygen-Free Copper?

After Silver, copper is the most conductive material accessible on earth, with copper wires being 66% more conductive than the same-size aluminum wires. For transferring the same volume of current in an 8 AWG copper wire, a 6 AWG aluminum conductor 25% thicker is required.

Though copper is susceptible to corrosion and can go greenish in color when it is exposed to oxygen, this outcome can be seen on old pennies or the Statue of Liberty. By eliminating the oxygen from the copper, oxygen-free copper is fashioned, dramatically improving its corrosion resistance.  The usage of OFC comes with understandable paybacks of improved current flow, enhanced conduction competence, and reduced ecological strain.

Types of Oxygen-Free Copper

There are mainly three oxygen-free copper grades.

• C10100

C10100 is chosen as oxygen-free electronic and attains a minimum conductivity score of 101% IACS under annealed conditions. This copper is recommended for applications needing high ductileness and electrical in addition to thermal conductivity.

• C10200

This is 99.95% pure copper. It is an idyllic choice when the material requires a strong confrontation against stress rust cracking. It likewise has outstanding welding, conductivity, and soldering characteristics.

• C11000

This type of copper is also called ETP. Though it is 99.9% pure, this has more oxygen than OFE copper, with the latter having below 10 ppm of oxygen, while ETP comprises a minimum of 150 ppm of oxygen. Though, ETP is the most regularly utilized grade for its intrinsic fabrication potential.

Benefits of Using Oxygen-Free Copper

The usage of OFC can be useful for precise applications. Mentioned below are some of the benefits.

Excellent Electrical Conductivity

Throughout the manufacturing process of OFC, the copper is treated in the existence of carbon to eliminate any oxygen. High-level purity, along with the absence of oxygen, lets more current pass through the same conductor size. Therefore, OFC is precisely used for induction coils, battery cables, and space heaters.

High Thermal Capacity

Because of higher conductivity, OFC copper wires do not heat as quickly as other metals like aluminum. Consequently, they also have greater thermal strength and conductivity. Industries profoundly depend on them for high-temperature applications like induction heating furnaces.

Outstanding Resistance to Hydrogen Embrittlement

Oxygen-free copper has excellent resistance against hydrogen embrittlement happening under wet electrochemical settings. For the reason of its pliability, weldability, and absence of reactivity in oxygen-free waters. Finland is making use of copper canisters for storing nuclear waste in an encapsulation plant.

Excellent Construction Properties

All oxygen-free coppers are apt for machining, with an outstanding machinability rating of 20. They have outstanding hot and cold working properties. All the copper grades are perfect for brazing, soldering, and gas shielding arc welding. Though, seam welding and spot welding are not suggested.

With the increasing fascination of the people toward electric vehicles, there is an increase in the demand for Oxygen-Free Copper all around the globe. And, what’s more, there is absolutely no stopping the inclination of people in the direction of electric vehicles.

What are the materials of chip resistors and their material classification and differences.

Chip resistor is also known as chip fixed resistor is one of the metal glaze resistors. It is a resistor made by mixing metal powder and vitreous enamel powder and printing it on the substrate by screen printing method. It is resistant to humidity and high temperature, and has a small temperature coefficient. It can greatly save the cost of circuit space and make the design more refined. The material classification of chip resistors, what are they and the differences are explained below.

Chip resistor type

First of all, first understand the type of chip resistors, chip resistor type reference international classification of conventional series thick film chip resistors, high precision high stability chip resistors, and conventional series thick film chip resistors have (low resistance chip resistors, chip resistor array, chip current sensor, chip network resistors, chip thick film resistance, chip wire resistance, chip high voltage resistors, chip power resistors, etc.); high precision high stability chip resistors stability chip resistors, ultra-precision ±0.01% ~ ±1%, TaN and NiCr vacuum sputtering, temperature coefficient of only ±5PPM/°C ~ ±50PPM/°C, medical equipment, precision measurement instruments, electronic communications, converters, printers are general consumer products.

Chip Resistor Material

Next chip resistor material is made of ceramic substrate, resistor paste, back guide material, positive guide material and side guide material, primary protection glass G16. secondary protection glass G27. mark mark material, and chip resistor is composed of four major parts respectively substrate, resistor film, protective film, electrode.

(1) substrate; substrate material is generally used 96% of the alumina trioxide ceramic. The substrate should have good electrical insulation in addition to the excellent thermal conductivity at high temperatures. Electrical properties and mechanical strength and other characteristics. It is also required that the substrate is flat and accurately scribed. standard to fully ensure the resistance. Electrode paste printing in place.

(2) resistive film; printed with a resistive paste with a certain resistivity onto a ceramic substrate, and then sintered. The resistive paste is generally made of ruthenium dioxide.

(3) protective film; the protective film is covered on the resistive film, mainly to protect the resistive body. It plays a mechanical protection role on the one hand, and makes the surface of the resistor body insulating on the other hand to avoid the failure of the resistor by contacting with the neighboring conductors. In the process of electro-transition intermediate electrode, it also prevents the erosion of the resistive film by the electro-transition liquid which leads to the degradation of resistive performance. Protective film is generally a low melting point glass paste, sintered by printing.

(4) electrode; is to ensure that the resistor has good solderability and reliability, generally using a three-layer electrode structure: inside. Middle. Outer layer electrode. The inner electrode is the internal electrode connected to the resistor body. The electrode material should be selected to have low contact resistance with the resistive film, strong bonding with the ceramic substrate as well as good chemical resistance, and easy to perform plating operations. Generally, it is made by printing and sintering with silver-palladium alloy. The intermediate electrode is a nickel-plated layer, also known as a barrier layer. Its function is to improve the heat resistance of the resistor during soldering and to buffer the thermal shock during soldering. It can also prevent the migration of silver ions to the resistor film layer, to avoid causing the phenomenon of internal electrode erosion (internal electrode is melted by the solder erosion) The outer electrode tin-lead layer, also known as the solderable layer. Its role is to make the electrode have good solderability and extend the electrode's shelf life. Generally plated with tin-lead alloy.

Chip resistor material classification

According to the manufacturing material can be divided into: carbon film resistors, metal film resistors, wirewound resistors, etc..

The difference of chip resistor material

Chip resistors are a large category, indicating that the package is in the form of surface mount package. And alloy resistor is a kind of resistor using alloy as the current medium, generally with low resistance, high precision, low temperature coefficient, resistance to inrush current, high power and so on. These resistors are commonly used in various electronic products, mainly in current sampling, or short circuit protection, etc.

The mainstream alloy resistor is chip alloy resistor. The main material of the alloy is copper, plus other materials into the Kang copper, manganese copper, etc.. Other auxiliary materials are numerous, but the main performance is determined by the alloy material itself.

And we often mentioned in the daily chip resistors, generally refers to the general type of chip thick film and film resistors.

The two concepts, that is, from different levels to classify.

Thick film is relative to thin film, from the point of view of materials and processes to classify.

A resistor, it may be thick film and chip, that is, with thick film printing process to make chip resistors, of course, thick film printing can also do thick film hybrid circuit, and chip resistors are also useful to make out of the film process;.

Price: alloy resistors are generally much more expensive than chip thick film resistors, about 0.1-0.2 yuan between, of course, the larger the package body, the more precision, the more expensive. And thick film resistor prices range from a few dollars to tens of dollars, also according to the package and precision difference.

the precision of alloy resistors is much more precise than thick film resistors, thick film resistors are generally 1% and 5%, while alloy resistors can reach less than 1%.

Prepare your supply chain

Buyers of electronic components must now be prepared for future prices, extended delivery time, and continuous challenge of the supply chain. Looking forward to the future, if the price and delivery time continues to increase, the procurement of JIT may become increasingly inevitable. On the contrary, buyers may need to adopt the "just in case" business model, holding excess inventory and finished products to prevent the long -term preparation period and the supply chain interruption.

As the shortage and the interruption of the supply chain continue, communication with customers and suppliers will be essential. Regular communication with suppliers will help buyers prepare for extension of delivery time, and always understand the changing market conditions at any time. Regular communication with customers will help customers manage the expectations of potential delays, rising prices and increased delivery time. This is essential to ease the impact of this news or at least ensure that customers will not be taken attention to the sudden changes in this chaotic market.

Most importantly, buyers of electronic components must take measures to expand and improve their supplier network. In this era, managing your supply chain requires every link to work as a cohesive unit. The distributor of the agent rather than a partner cannot withstand the storm of this market. Communication and transparency are essential for management and planning. In E-energy Holding Limited, we use the following ways to hedge these market conditions for customers:
