BEST Inc. Publishes Optimizing BGA Rework Techniques to Ensure Quality Tech Paper

Estimated reading time: 1 minute

BEST Inc., a leader in electronic component and PCB services, is pleased to announce they have published a tech paper describing techniques for reworking BGA components to ensure quality during the printed circuit board rework process.

This technical paper encompasses critically important information about the BGA rework process and is entitled “Optimizing BGA Rework: Addressing Challenges, Implementing Techniques, and Ensuring Quality Control.” 

Topics covered within this publication include common BGA rework methods, equipment and skill requirements, typical BGA challenges, adjacent device damage, large BGA packages, underfilled BGAs, component and PCB warpage, fine pitch micro BGA device warpage, mirrored BGAs, package-on-package, BGA reballing, inspection of BGA rework, visual inspection, X-ray imaging, as well as dye and pry testing.

BGA rework is often regarded as a necessary, yet an inherently challenging aspect of electronic manufacturing. Since it is rarely planned during the initial design phase, rework procedures frequently involve overcoming a variety of obstacles that were not anticipated. Successfully navigating these challenges depends heavily on operator experience, the use of advanced equipment, and sometimes thinking creatively to develop effective problem-solving strategies. The process is further complicated by factors such as underfilled components, warpage, and the proximity of neighboring devices, all of which require careful consideration and strategic approaches during rework.
