Flip chip solder ball void
Web2 days ago · Most suitable for Ball Grid Array, Multi-Chip Module, Chip On board Flip Chip and CSP. The Solder Ball industry can be broken down into several segments, Lead Solder Ball and Lead Free Solder Ball. WebAn essential process for flip chip packaging is wafer bumping. Wafer bumping is an advanced packaging technique where ‘bumps’ or ‘balls’ made of solder are formed on the wafers before being diced into individual chips. ASE has invested significantly in the research and development as well as in equipment for wafer bumping.
