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

New Materials and Technologies for Additive Manufactured Defence applications

For European Union, Albania, Armenia, Bosnia and Herzegovina, Faroe Islands, Georgia, Iceland, Israel, Moldova, Montenegro, North Macedonia, Norway, Serbia, Switzerland, Tunisia, Turkey, Ukraine

Additive manufacturing (AM) allows production of parts for various defence-industries segments with various technologies and materials. AM can, for instance, improve development processes due to shorter production times, manufacture obsolete spare parts or parts on-demand, or produce parts with integrated functions or parts of high complexity. There are several topics related to AM that can be addressed in research activities. These activities could include but not be limited to: the identification and analysis of material properties, such as (super)alloys or concrete composites, full functional 3D printed electrified structures, specialized AM-materials for advanced ammunition and missiles or AM technologies for ballistic functional structures.

- Proposals should in particular address R&T efforts in the areas of:

- Identification and analysis of new materials for AM for defence application

- Innovative AM technologies and procedures, e.g. for the production of multi-functional parts

Proposals should address R&T efforts in one or more of the following areas:

A Additive Manufactured Electronics (AME)

In order to overcome future challenges in defence electronics, the aspects of increased miniaturisation and complexity is of major importance. Furthermore, SWaP-C needs to be considered, too. In case of damage, defence electronics should be replaced as soon as possible and not depend of the availability of spare parts. Therefore, the impact of supply chain management and their impact to the independency from outer EU regions is vital. Finally, classical manufacturing of PCBs is related to significant numbers of harmful substances, like acids or galvanic fluids. This is directly related to RoHS and REACH requirements.

B Additive Manufacturing of Advanced Ammunition

For the next generation of ammunition several challenges need to be addressed, e.g. increased performance, improved reliability and safety, additional functionality, changing requirements and adequate supply. AM can be used to produce ammunition covering both, the production of the body/shell and the high-energetic material. The high degree of freedom in shape, can led to significant improvements in performance as the ammunition can be designed and adopted to several mission-specific requirements. For example, pressure profile in a barrel can be improved by the design of the energetic-material or the fragmentation of a shell can be influenced by the shape of the casing.

C Additive Manufacturing for Protection

Different groups of additive manufacturing technologies provide the opportunity to improve the protection of soldiers and equipment by advanced approaches to avoid or resist threats. Using the flexibility in terms of shape and complexity, AM parts or structures can be manufactured without the restriction of classical technological limits. Particularly for resistance it is important to absorb energy and withstand high-strain rates, where AM structures can show an improved protection quality and/or reduced weight.

D Additive Manufacturing for Lightweight Structural Parts

Lightweight structures can be achieved through a geometrical lightweight design and/or the use of lightweight material. AM offers the opportunity to address both by taking advantage of the freedom in the shape using (new) lightweight materials leading. Additionally, using AM for structural parts leads to the necessity of safe and robust processes leading to high-quality products.

Scope:

Proposals should consider the current state-of-the-art including additive manufacturing systems, materials and material properties. Additionally, the entire additive manufacturing process should be taken into account in order to evaluate and classify the planned activities within a project. Proposals are generally intended:

- To improve the understanding of the investigated AM-processes

- To further develop the manufacturing technology

- To evaluate the potential compared to other solutions

- To improve the performance of the products, processes or operations addressed by the proposal

For the previously mentioned areas, this means:

A Additive Manufactured Electronics (AME)

To increase the level of integration regarding electronics and RF-components, multiple physical functions should be integrated in multi-functional parts using AM, e.g. mechanical, thermal and especially the electric function. Due to the potential design freedom AME can merge mechanical and electrical functions in one multifunctional structure. Future designs could handle concurrent requirements regarding weight reduction, increased complexity, rapid manufacturing and reduced environmental impact. Challenging factors to get AME in use at defence level are manufacturing process maturity, definition of material properties and population technologies (e.g. soldering, multi-layering). Additionally the ability to create these functional designs is equally important. Therefore, the education of engineers and definition of design guidelines are therefore the key to implement AME successfully.

B Additive Manufacturing of Advanced Ammunition

Different types of ammunition may be investigated e.g. kinetic projectiles, shaped charges, grenades or high and hypervelocity ammunition. The specialized materials must be characterized and tested with respect to their intended use, e.g. high-density materials needed for kinetic projectiles.

To improve and adopt the behaviour of ammunition items energetic materials may be additively manufactured to affect the time-dependent energy conversion. To affect fragmentation gradients in the material properties within a shell may be investigated as well as a complex design of ammunition bodies/shells. To affect propulsion, complex shaped propellant grains may be investigated.

The quality and accuracy of the AM-process and the AM-processed materials should receive special attention.

C Additive Manufacturing for Protection

To increase protection different combinations of materials and technologies may be used at each stage of manufacturing process. Different densities, internals structures of components should be considered here, e.g. to optimize the protection quality /mass ratio. AM may be used to exclusively manufacture or just perform the modifications of the existing parts. Multimateriality and multifunctionality of the parts may be additionally implemented.

D Additive Manufacturing for Lightweight Structural Parts

Lightweight structures are to be realized addressing both aspects, an optimal distribution of the material as well as improved (weigh-specific) material properties. Therefore, complex designs are to be addressed as well as the use of new materials. Due to the typically low safety factors used for many lightweight applications, special attention should be paid to process and material quality as well as an substantial database, which should be built up for the processed materials.

AMD’s RX Vega 56 finally gets miniaturised - but can it cope under pressure?

Forget the 7nm Vega shrink, Powercolor are set to launch the AMD RX Vega 56 ‘Nano Edition’ next month, bringing small form factor Radeon power to the desktop. And this one will  be a gaming card.

A little more space in your PC case? Here are the best AMD graphics cards to fill the void.

Since AMD launched their RX Vega graphics cards, gamers with loyalties to the red camp have been wondering when either AMD, or one of their board partners, would ever make the most out of the compact PCB. Well, today’s the day, PowerColor are preparing to launch their ‘Nano Edition’ RX Vega 56 at Computex.

HBM2 memory was one of the biggest selling points for AMD’s RX Vega graphics cards, but one of the often overlooked features - largely overshadowed by their headline bandwidth capabilities - is the memory chips’ compact nature due to their implementation within the same package as the GPU.

If you look at an RX Vega PCB (printed circuit board) you’ll find it really rather sparse in comparison to a similar spec Nvidia card - aside from power delivery, they are largely bare. Sapphire already shortened the PCB with their Pulse RX Vega 56 graphics card, but this card still made the most of a full-sized GPU cooler and heatsink design to pull away all the heat generated by the toasty GPU.

Exploring the Wonders of PCB Circuit Design: Paving the Path to Technological Breakthroughs

PCB circuit design is essential to powering innovation and advancing technology in today’s ever-evolving world. The foundation of contemporary electronic devices is the printed circuit board (PCB), which is used in everything from consumer electronics to medical equipment, aircraft systems, and automotive applications. This essay goes deeply into the field of PCB circuit design, revealing its marvels and highlighting its importance in facilitating technological advances.

Knowledge of PCB Circuit Design

1. PCB Circuit Design: What Is It?

The process of developing a printed circuit board’s layout and structure is known as PCB circuit design. To assure the performance and functionality of electronic equipment, it includes the positioning of components, the routing of electrical connections, and the integration of numerous aspects. PCBs act as the structural framework connecting and supporting electronic components and acting as a conduit for the movement of electricity.

2. Designing PCB Circuits: Its Importance
