Alpha Solder Wire Enables Long-Term Reliability and Reduced Costs


Reading time ( words)

Alpha Assembly Solutions has introduced a low-temperature solid solder wire that demonstrates long-term reliability while enabling the use of less expensive PCB materials.

The ALPHA Sn42 Bi57.6 Ag0.4 is a lead-free solid solder wire primarily used for rework operations and touch up soldering of low temperature based electronic assemblies. Compatible with all commonly used lead-free surface finishes, this low temperature solution is ideal for soldering sensitive components or connectors. It is available in various wire diameters (min: 0.6mm) and is more versatile than SnBiAg alloy solid solder sticks.

"The ability to use low temp compatible components and low Tg PCBs leads to a reduction of waste and scrap that can lead to a significant savings in material costs," said Bernice Chung, Global Product Manager for Solid Solder Wire at Alpha Assembly Solutions, a part of the MacDermid Performance Solutions Group of Businesses. "The SnBiAg alloy allows us to reduce exposure to thermal excursion during assembly, thereby eliminating the need for a wave soldering process which both increases long-term reliability and reduces energy costs."

This new soldering material from Alpha eliminates the need for additional reliability testing of solder joints reworked with an alternative alloy.

Evaluation of Stencil Technology for Miniaturization

12/22/2017 | Neeta Agarwal, et al.*
SMT stencil printing technology continually evolves to keep pace with device miniaturization technologies. Printed circuit board assemblers have numerous new technology options to choose from, and need to determine the most effective ones to produce the highest quality and most reliable solder interconnections.

Solder Printing Process Inputs Impacting Distribution of Paste Volume

12/14/2017 | Marco Lajoie and Alain Breton, C-MAC Microelectronics
The volume of solder deposition, like any process, has variations that may be characterized by a statistical distribution curve, whether normal or non-normal. As complexity, density, cost and reliability requirements increase, there may be value in narrowing the distribution curve. It is common sense that less variation serves the interest of quality of the more complex and dense circuit boards.
