Flip chip solder ball void
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. WebThe solder balls can be placed manually or by automated equipment, and are held in place with a tacky flux. A coined solder ball is a solder ball subject to coining, i.e., flattening to a shape resembling that of a coin, to increase contact reliability. The ball grid array, chip-scale package, and flip chip packages generally use solder balls.

WebSolder bumps (3% Sn, 97% Pb) on the die surface are joined with solder pads (60% Sn, 40% Pb) on the organic substrate in a reflow furnace. These joints form the electrical/ mechanical connection between the FC die and the OLGA package. An epoxy underfill fills the gap between die and the substrate.
