Lead-free reflow soldering techniques applying AuSn as well as SnAg electroplated bumps were chosen for the evaluation of the flip-chip-bonding process for X-ray pixel detectors. Both solders can be used in pick-and-place processes with a subsequent batch reflow suitable for high-volume production. AuSn solder was selected because of its fluxless bondability, good wettability, and self-alignment process...
As far as components with flip chip interconnects are concerned, one of the popular packaging solutions available in the market is thermally enhanced flip chip ball grid array (TEFCBGA) packages, which target mid to high performance applications. Traditional as it may be, the development of a reliable TEFCBGA package is still a very challenging task. The demands for high electrical performance with...
3D contactless technology based on capacitive coupling represents a promising solution for high-speed and low power signaling in vertically integrated chips. AC coupled interconnects do not suffer from mechanical stress, and the parasitic load is much reduced when compared to standard DC solutions, such as wire bonding and micro bumps. Communication system based on wireless interconnection scheme...
