While it provides flexibility and customization, issues are almost inevitable, especially if you're new to the process. Troubleshooting your bare board setup can save you time, money, and frustration. In this guide, we’ll walk you through common issues and practical solutions.

Understand Your Bare Board

A bare board is essentially the foundation of your circuit — the unpopulated printed circuit board (PCB). It contains the traces, pads, and holes needed to connect electronic components. Ensuring its quality and compatibility with your project is the first step toward a successful setup.

Common Bare Board Setup Issues and Fixes

Issue 1: Poor Connectivity or Circuit Malfunction

If your circuit isn’t working as expected, the issue might stem from poor connectivity. This can happen due to incorrect soldering, damaged traces, or cold solder joints.

Fix:

Inspect the board for visible damage or broken traces. Use a magnifying glass or microscope for better visibility.

Use a multimeter to check continuity between points.

Re-solder joints that appear dull or cracked, ensuring the solder flows smoothly to establish a solid connection.

Issue 2: Components Not Fitting Properly

Components may not align with the bare board, causing difficulty during assembly. This is often due to mismatched footprints or manufacturing tolerances.

Fix:

Verify that the components match the board design specifications before starting.

Use a fine file or sandpaper to adjust oversized pins, but be cautious not to damage the components.

If footprints are slightly off, bend component leads carefully to fit.

Issue 3: Overheating During Soldering

Excessive heat can damage both the bare board and the components, leading to burnt pads or weakened traces.

Fix:

Use a temperature-controlled soldering iron set to the recommended temperature (typically 300–350°C for most soldering tasks).

Apply heat only long enough to melt the solder. Practice quick, precise soldering techniques.

Consider using a heat sink clip to protect sensitive components.

Issue 4: Unstable Power Supply

A fluctuating or insufficient power supply can cause erratic behavior in your circuit.

Fix:

Double-check your power supply voltage and current ratings to ensure they meet the project requirements.

Test the power rails on your bare board with a multimeter.

Add decoupling capacitors near power pins to stabilize the voltage.

Issue 5: Shorts and Grounding Problems

Short circuits or poor grounding can lead to a completely non-functional setup.

Fix:

Inspect for accidental solder bridges, particularly between closely spaced pins. Remove excess solder with a desoldering braid or pump.

Ensure all ground connections are properly established and connected to a common ground plane.

Use insulating materials to prevent accidental contact between traces or components.

Issue 6: Incorrect Component Orientation

Placing polarized components like diodes, LEDs, or electrolytic capacitors incorrectly can prevent your circuit from functioning.

Fix:

Always verify the polarity before soldering. Refer to the component datasheet or markings on the board.

If a mistake is made, carefully desolder the component, ensuring you don’t damage the pads, and re-install it correctly.

Conclusion

Fixing issues with your bare board setup requires patience, attention to detail, and the right tools. By systematically addressing problems like poor connectivity, overheating, or improper assembly, you can ensure a reliable and functional setup. Remember, each mistake is a learning opportunity, and with practice, troubleshooting your bare board will become second nature.

Through Hole PCB Assembly

THT PCB Assembly Manufacturer – One-stop service

[email protected]

What’s mean for Through Hole (THT) PCB Assembly and Surface Mount Technology（SMT）PCB Assembly ?

Surface Mount Technology (SMT) is necessary for PCB assembly. If the PCB has no through-hole components, Through Hole (THT) PCB Assembly is not needed.

SMT assembly: SMT stands for surface mount technology, which is a versatile PCB assembly technology. Currently, all electronic components can be made into surface-mounted devices (SMD). SMDs are interconnected to the PCB pads with solder paste. SMT assembly is automatic.

THT assembly: THT, or PTH or DIP, means through-hole technology. The electronic components that require THT assembly have long pins. Usually, they are capacitors, fuses, and connectors. The PCB is pre-drilled, and these components' pins plug in the holes and wave reflowed. THT assembly is manual.

In the PCB assembly process, SMT assembly happens before the THT assembly.

What are the benefits of Through Hole PCB assembly?

Through-Hole PCB Assembly comes with a range of benefits including:

Withstanding stress-As opposed to SMT components, through-hole components are known for their ability to withstand mechanical and environmental stress.

Perfect for large components-Through-hole works well for large components that have to undergo high power and high voltage

High heat tolerance-Known for their high heat tolerance, they find application in a number of industries, particularly military and aerospace.

Ease of Prototyping- Through-hole PCBs also lend themselves to ease of prototyping and improved reliability

High Reliability-Through-hole PCBs are best used for high-reliability products that require stronger connections between layers.

Little surprise then, that even though surface mount components allow for denser configurations, for larger and heavier components that require strong bonds, through-hole technology has remained resilient and relevant.

What are the capabilities you offer for Through Hole PCB assembly?

We provide through-hole PCB services to a variety of industries including medical, electronics, instrumentation, and military, all thanks to our complete assembly capabilities:

• Hand soldering

• Dual wave flow solder

• Hand Insertion of components

• Automate axial or radial insertion

• RoHS soldering using tin-lead solder

• Use of high and low melting point solder

• Prototype build to high-volume assembly

• Functional test and automated inspection

• Support various types of PCBs including metal core PCBs, Rigid PCBs, Flex-rigid PCBs, FR4 PCBs, etc.

Disadvantages of Through Hole Assembly

Like any other manufacturing or assembling techniques, Through Hole PCB Assembly has its disadvantages too.

These include:

Longer production time-It takes a lot of time to drill the multiple holes through which the leads are expected to run.

Expensive-because the drilling process is difficult and time-consuming, it increases the cost of production

Minimizes space on the boards-drilling the holes on the surface of the board limits the routing area for tracing signals.

Also, by feeding the leads through the board, only one of its sides is usable, thus making the THT PCB a bit slower in operation speeds.

Through Hole Assembly Components – What are the Best Components for Through Hole Assembly?

Radial lead components

Axial lead components.

Types of Through Hole PCB Assembly

There are two (2) main types of the Through Hole PCB Assembly. The first is the Automated Through Hole PCB Assembly. The second is the Manual Through Hole PCB Assembly.

On the one hand, the automated variant is roundly touted to be faster and cost-effective because it takes little time to be completed. It also demands little human inputs, which makes it cost-effective.

On the other hand, the manual Through Hole PCB Assembly involves the traditional or manually-operational model of drilling the holes into the Printed Circuit Boards (PCBs). This model tends to take time and attracts more costs.

Functional tests and automated inspection for Through Hole PCB Assembly

Using automated inspection is very critical in minimizing turnaround time to ensure timely delivery of the boards.

Conclusion

As you can see, Through Hole Assembly of PCB can be time consuming.

However, in some applications, it is worth it more so when mounting heavier and bulkier components.

You can easily achieve the strength by soldering the components on the reverse side as you have seen.

In fact, it is virtually impossible to pull components assembled using Through Hole Assembly.

The good news, today’s guide has simplified the Through Hole PCB Assembly technique.

In addition to through hole PCB assembly, we also provide value-added services, such as conformal coating, labeling, and complete PCB encapsulation.

Through-hole PCB Assembly Testing and Inspection at Hitechpcba

In-Circuit Testing:

This type of testing is conducted for high volume production lines, and helps us check every minute soldering and other components in detail.

Automated Optical Inspection: Abbreviated as AOI, these tests are performed to ensure that product is free from soldering, component, and BGA defects.

Automated X-Ray Inspection(AXI):

This testing is performed to inspect insufficient fills, short circuits, fills, etc. The automated X-ray inspection helps reduce the number of defects and improve the quality of the Through-Hole circuit.

Burn-in Tests:

These tests detect components’ failure or reliability in real environments.

Assisted Visual Inspection:

Our experts use a wide range of advanced visual inspection equipment to perform a detailed inspection of soldering and component placement accuracy.

What’s difference between SMT assembly and THT assembly?

Most contract PCB Assembly manufacturers concentrate on their surface mount technology capabilities for PCB assembly. The SMT lines can be almost completely automated making it possible to run a high volume of boards with little human intervention and a low cost per board. Through whole assembly whether automated or manual is a slower process, it takes resources away from the high-volume business that many manufacturers prefer.

Only about 10 percent of the parts we buy are through-hole. Nearly 75 percent of the boards we run are mixed technology, which is a combination of through-hole and SMT parts one reason for this is that nearly half of our board assemblies are for high powered boards which use capacitors inductors and transformers to transfer energy. The size of these components is proportional to the energy they can store so for a high-power board we need to use some fairly large and heavy components and that means through-hole technology, in addition things like customer accessible connectors, that have to withstand stress as cables are connected and removed are likely to be through-hole components. Through-hole components are held in place by the pins as well as the solder so you can get a much stronger and more reliable mechanical bond than with surface mount components that have only solder to hold them in place. If a contract manufacturer is focused on higher volume SMT business, it's important to understand how they will handle through-hole components when you need them at z-axis. We run mixed technology boards every day we have a modern stuff line with a paperless process for assembly instructions and assemble in a single piece flow from the stuff line to a wave solder to inline inspection, d-paneling, qc testing.

In addition to PCB Assembly, be it through hole or surface mount, at Hitech Circuits Co., Limited we also undertake PCB assembly rework offering complete reliability, high quality and optimal costs. Not only are we well-versed in inventory management, fabrication and process control, we also have a stringent control on vendor component management.

Understanding Cold Solder Joints | Causes and Prevention | Lion Circuits

In the realm of electronics, soldering is a fundamental process that ensures reliable connections between components and printed circuit boards (PCBs). However, not all solder joints are created equal. One common issue that can undermine the integrity of an electronic assembly is the presence of cold solder joints. At Lion Circuits, we emphasize the importance of recognizing and preventing cold solder joints to ensure the longevity and performance of your electronic devices.

What Are Cold Solder Joints?

Cold solder joints occur when solder fails to properly melt and flow during the soldering process. Instead of forming a solid, shiny connection, the joint appears dull and rough, often characterized by poor adhesion to the PCB or component leads. This can lead to unreliable electrical connections, intermittent performance, or even complete circuit failure.

Causes of Cold Solder Joints

Insufficient Heat: One of the primary causes of cold solder joints is inadequate heating of either the solder or the components being joined. If the soldering iron temperature is too low or the application time is insufficient, the solder won’t melt properly, leading to a poor joint.

Dirty Surfaces: Contaminants such as dirt, grease, or oxidation on the surfaces to be soldered can prevent proper adhesion. A clean surface is crucial for ensuring that the solder can form a strong bond.

Movement During Cooling: If the components are disturbed while the solder is cooling, it can result in a weak joint. Movement can cause the solder to solidify in an improper shape, leading to a cold solder joint.

Wrong Soldering Technique: Using an inappropriate soldering technique, such as applying the solder directly to the iron instead of the joint, can lead to uneven heating and insufficient solder flow.

Preventing Cold Solder Joints

Proper Temperature Settings: Ensure that your soldering iron is set to the correct temperature for the type of solder you’re using. A typical lead-based solder works well at around 350°C (662°F).

Clean Surfaces: Always clean the areas to be soldered. Use isopropyl alcohol and a lint-free cloth to remove any contaminants. Additionally, using flux can help improve solder flow and adhesion.

Steady Hands: Avoid moving the components while the solder is cooling. Allow enough time for the solder to solidify without any disturbances.

Practice Good Technique: Apply the solder to the joint, allowing it to flow around the connection. Make sure the solder covers both the pad on the PCB and the lead of the component.

Conclusion

Cold solder joints can significantly affect the performance and reliability of electronic devices. Understanding what causes these joints and how to prevent them is crucial for anyone involved in PCB assembly or soldering. At Lion Circuits, we are committed to delivering high-quality soldering practices to ensure robust connections in every project.

What Is Polyimide PCB?

To understand the real meaning of polyimide PCB, at first, you will have to know about the ‘polyimide’ properly.

The word polyimide consists of two sub-phrases that includes, ‘poly’ which typically refers to polymers and ‘imide’ which refers to the advanced imide monomers. Together they create a diverse polymer group.

Moreover, the polymer group is manufactured using either natural or synthetic process. However, for now, forget about the natural polymers and focus on the synthetically manufactured polyimides. These polyimides are used to build the PCBs, hence the name polyimide PCB.

The synthetic polyimide used in manufacturing PCBs is resourced from different chemicals with imide structures. This manufacturing process is known as polymerizing to us. These polyimides are then used in making PCBs.

Different Types of Polyimide PCBs

Likewise, metal PCB and ceramic PCB, the polyimide made printed circuit boards also have multiple types. These classification has been made by determining the material used in synthesizing the amide polymer or polyimide.

The most common polyimide PCBs are:

Pure Polyimide or 2nd Generation Polyimide:

This is the simplest PCBs and lacks additional features such as brominated flame retardants. While the word ‘lacking’ is used negatively for most materials, pure polyimide has used it positively. The lack of flame retardants makes it extremely stable while still being flexible enough to use in different electrical and communicating devices. The polyimide is also occasionally called as polyimide flex PCB, mainly because of its useful flexibility.

Although it is the oldest of all polyimide PCB types, pure polyimides have widespread use. It is made possible thanks to the extreme endurance against temperature change and thermal stability during challenging situations.

3rd Generation Polyimide:

It is an updated version of pure polyimides. Also, it has additional additives which effectively make it more flammability resistance. The flammability resistance is crucial because it comes forward in stopping accidental electric fires.

However, the 3rd generation polyimide lacks the thermal stability of pure polyamides which can be a disadvantage for it. On the contrary, it is easy to manufacture, which propels the production line faster than any other polyimide flexible PCB.

So, you can manufacture the 3rd generation polyimide in bulk which lies in its vast favour.

Filled Polyimide:

This type of polyimide is similar to multilayer PCBs since it comes with more than one filler materials. The additional filler lowers the resin shrinkage.

The resin shrinkage resistance is vital since due to the shrinkage, many printed circuit boards become frail and cracks down during the drilling and curing proceedings. Also, the shrinkage resistance helps the filled polyimide maximize its long-term usage.

Low-Flow Polyimides:

The low-flow polyimides are made without the flexibility of the standard PCBs. So, sometimes people also refer to it as the rigid polyimide PCB.

The rigidity of the low-flow PCB comes useful when PCBs require stiffness to stay strong during the challenging conditions. So, when the traditional flexible PCBs fail, the low-flow polyimides come forward to solve the tough situations.

Benefits of Polyimide PCB

Since the polyimide PCB is a particular type of printed circuit boards, it is mainly used on special occasions. So, it would help if you understood when to use the polyimide PCB and when not to. Use the polyimide made PCBs when you need either one or all of the following characteristics:

Stable flexibility: The greatest benefit of the polyimide PCBs is its extreme stability and flexibility at the same time. It is a perfect combination of rigidity and flexibility which regular PCBs lack.

Tensile strength: Polyimide PCBs have excellent resistance against warping. It is made possible thanks to the flexibility of the polyimide materials. So, if you want durability for the PCB applications, the superior tensile strength and durability will be beneficial for you.

Thermal stability: Polyimide materials are known for having superior thermal endurance and resilience. So, the polyimide made PCBs are capable of working even at 260° temperature. Furthermore, thermal conduciveness prevents thermal damage during manufacturing and repairing jobs.

Extreme durability: Polyimide has resistance against various chemicals and temperature. So, it enjoys enhanced durability. The durability is essential to endure extreme physical stress which is a necessary benefit for PCBs.

Versatile Usage of Polyimide PCB

Both the rigid polyimide PCB and polyimide flexible PCBs are widely used in different industries. The most common applications of the polyimide PCBs are:

Computer and Laptops:

Modern-day laptops and computers suffer from heavy-duty usage and go through the extreme thermal rise of the components. Thus, the thermal conduciveness of the polyimide PCBs is beneficial for laptops and PCs.

Also, the flexibility and rigidity of these circuit boards come forward to enhance the overall durability of the computers.

Automotive Electronics:

Out of all electronic components, automotive electronics face the most challenging conditions. They need to function both in extreme cold and summer along with continuous jostling f multiple components.

Naturally, these automotive components ask for a durable PCB, which only the polyimide can supply.

Military and Aerospace:

Both the aerospace and military industry uses the most advanced electronics for their superior performance and safety requirements. Also, in both industry electronics component operates in the most hostile environment.

So, the durability and thermal stability of polyimide made PCB is essential to safeguard these components, which can be the ardent difference between life and death of millions.

Medical Industry:

Various medical treatments and diagnosis such as advanced imaging, implants and prosthetics require high-efficiency applications. This useful and high-performing efficiency will only come from the polyimide PCBs.

Differences Between FR4 and Polyimide PCB

When you know the factual distinctions between polyimide PCB and FR4, you will be able to pick the perfect printed circuit board for your desired jobs.

FR4 circuit boards are made of epoxy glass resin and laminated copper. So, it is rigid and not as flexible as the polyimide material. Also, polyimide is lightweight and more durable. Besides, polyimide also has better chemical and heat resistance compared to the FR4.

Last but not least, polyimide boards are more expensive the FR4. But its durability and widespread usage balance the overpricing to a greater extent.

The following table will help you understand the differences better between the FR4 PCB and polyimide PCBs-

Polyimide PCB with its great flexibility and extreme resistance to heat and chemicals is preferred in the aerospace industry. In fact, it has changed the aerospace industry quite brilliantly.

Who makes the best Polyimide PCB?

Many companies build polyimide PCBs and serve them in the market. But, not all of them are reliable. Hence, you must pick the right polyimide circuit board manufacturer for your works.

An ideal polyimide manufacturer will work with the highest-quality polymer plastics for the best flexibility and thermal resistance of the boards. Also, it should be able to offer you different types of polyimide circuit boards so you can easily get the right circuit boards.

Hitech Circuits can be a reliable source in this regard. Hitech Circuits with 15+ years of experience in manufacturing different types of PCBs will offer you tailored offers and the highest-quality PCBs. We manufacture both polyimide and FR4 circuit boards.

The Essentials of PCB Assembly: A Comprehensive Guide

Printed Circuit Boards (PCBs) are the backbone of modern electronic devices. They connect and support various electronic components, facilitating the flow of electrical currents and signals. PCB assembly is the process of integrating these components onto the board to create a functional electronic device. This blog will explore the intricacies of PCB assembly, its stages, and its significance in the electronics industry.

Understanding PCB Assembly

PCB assembly (PCBA) is a multi-step process that involves mounting electronic components onto a PCB. The assembly process can be broadly divided into two categories: Surface Mount Technology (SMT) and Through-Hole Technology (THT). SMT involves placing components directly onto the surface of the PCB, while THT requires inserting component leads through holes in the PCB and soldering them in place.

Key Stages of PCB Assembly

Solder Paste Application: The process begins with applying solder paste to the PCB. This is typically done using a stencil to ensure that the paste is applied only to the areas where components will be placed. The solder paste consists of tiny solder balls suspended in flux, which helps the solder adhere to the board.

Component Placement: Once the solder paste is applied, the next step is to place the electronic components onto the PCB. In modern manufacturing, this is often done using automated machines known as pick-and-place machines. These machines accurately place components onto the board based on the design files.

Reflow Soldering: After the components are placed, the board is passed through a reflow oven. The oven heats the solder paste, causing it to melt and form solid solder joints, which securely attach the components to the PCB. Once the board exits the oven, the solder cools and solidifies, forming a strong mechanical and electrical bond.

Inspection and Quality Control: Quality control is crucial in PCB assembly to ensure the reliability and functionality of the finished product. Inspections can be performed manually or using automated optical inspection (AOI) systems. These systems check for various defects, such as solder bridging, missing components, and misalignments.

Through-Hole Component Insertion: For boards that require through-hole components, the insertion process can be manual or automated. The leads of the components are inserted through the holes and soldered in place, usually using wave soldering or selective soldering techniques.

Functional Testing: After assembly, the PCB undergoes functional testing to verify that it operates as intended. This testing can include electrical tests, in-circuit tests (ICT), and functional tests. Any issues detected during testing are addressed and corrected.

The Importance of PCB Assembly

PCB assembly is a critical phase in the electronics manufacturing process. The quality and precision of the assembly directly impact the performance and reliability of the final product. Here are some reasons why PCB assembly is essential:

Miniaturization: Modern electronic devices are becoming increasingly compact. PCB assembly techniques, especially SMT, enable the placement of small, densely packed components, allowing for the miniaturization of electronic devices.

Cost-Effectiveness: Automated PCB assembly reduces labor costs and increases production speed. High-volume manufacturing benefits from economies of scale, making electronic products more affordable for consumers.

Reliability: Proper PCB assembly ensures robust connections and reduces the risk of component failure. High-quality assembly processes result in reliable and durable electronic devices.

Innovation: Advancements in PCB assembly technology drive innovation in the electronics industry. New assembly methods and materials contribute to the development of cutting-edge electronic products.
