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.
SolderKing’s Successful Approach to Modern Soldering Needs
06/18/2025 | Nolan Johnson, I-Connect007Chris Ward, co-founder of the family-owned SolderKing, discusses his company's rapid growth and recent recognition with the King’s Award for Enterprise. Chris shares how SolderKing has achieved these award-winning levels of service in such a short timeframe. Their secret? Being flexible in a changing market, technical prowess, and strong customer support.
Preventing Surface Prep Defects and Ensuring Reliability
06/10/2025 | Marcy LaRont, PCB007 MagazineIn printed circuit board (PCB) fabrication, surface preparation is a critical process that ensures strong adhesion, reliable plating, and long-term product performance. Without proper surface treatment, manufacturers may encounter defects such as delamination, poor solder mask adhesion, and plating failures. This article examines key surface preparation techniques, common defects resulting from improper processes, and real-world case studies that illustrate best practices.
Breaking Silos with Intelligence: Connectivity of Component-level Data Across the SMT Line
06/09/2025 | Dr. Eyal Weiss, CybordAs the complexity and demands of electronics manufacturing continue to rise, the smart factory is no longer a distant vision; it has become a necessity. While machine connectivity and line-level data integration have gained traction in recent years, one of the most overlooked opportunities lies in the component itself. Specifically, in the data captured just milliseconds before a component is placed onto the PCB, which often goes unexamined and is permanently lost once reflow begins.
