Chain Wire Bonding of a RF SOE Package Using a Gold Ball BonderDownload the Paper!
RF-SOE power transistors are traditionally wire bonded using gold wedge bonders to create strings of loops with each loop in the chain having specific length and height requirements.
A ball bond technology (chain bonding) to create a ball-loop-stitch-loop-stitch-loop-stitch … is demonstrated as a more cost effective alternative to these traditional wedge bond solutions.
Initial chain bonding using a ball bonder produced comparable performance as a wedge bonded solution, but used more prevalent ball bonding technology to reduce interconnect cost of ownership.
