Alpha Launches Ultra-Low Voiding Solder Paste for Vacuum Solder Reflow
December 12, 2018 | Alpha Assembly SolutionsEstimated reading time: Less than a minute
Alpha Assembly Solutions has recently introduced ALPHA OM-355, designed specifically for vacuum soldering applications.
“Inline vacuum soldering capabilities are becoming more common as power density increases on BGAs and as BTC component packages require effective heat dissipation through void reduction”, said Paul Salerno, global portfolio manager for SMT Solutions at Alpha Assembly Solutions. “This solder paste has an activator system that is optimized for the vacuum soldering reflow process to control the rate of volatilization and reduction in surface tension which allows voids to escape under reducing atmosphere. This promotes ultra-low voiding below 5% without the post-reflow defects commonly associated with vacuum soldering.”
Part of Alpha’s Void Reduction Solutions, ALPHA OM-355 is compatible with SAC305, Innolot and MAXREL Plus alloys.The ALPHA OM-355 MAXREL Plus solder paste is intended for final assemblies in automotive, defense, aerospace, telecommunications, or any device requiring power management and high reliability.

Fresh PCB Concepts: Assembly Challenges with Micro Components and Standard Solder Mask Practices
06/26/2025 | Team NCAB -- Column: Fresh PCB ConceptsMicro components have redefined what is possible in PCB design. With package sizes like 01005 and 0201 becoming more common in high-density layouts, designers are now expected to pack more performance into smaller spaces than ever before. While these advancements support miniaturization and functionality, they introduce new assembly challenges, particularly with traditional solder mask and legend application processes.
Knocking Down the Bone Pile: Tin Whisker Mitigation in Aerospace Applications, Part 3
06/25/2025 | Nash Bell -- Column: Knocking Down the Bone PileTin whiskers are slender, hair-like metallic growths that can develop on the surface of tin-plated electronic components. Typically measuring a few micrometers in diameter and growing several millimeters in length, they form through an electrochemical process influenced by environmental factors such as temperature variations, mechanical or compressive stress, and the aging of solder alloys.
