> News-Blog > Guideline for wire bonding Guideline for wire bonding Tuesday,Jun 12,2018 There are two wire bonding processes that are used, Thermosonic (T/S) Gold Ball Wire Bonding and Ultrasonic (U/S) Aluminum Wedge Wire Bonding. Approximately 90% of all IC Assembly in Semiconductor Packages is manufactured using Gold Ball Bonding process, while Aluminum Wedge Bonding is used to produce about 10% of other Wire Bonding requirements on Printed Circuit Boards (PCB), Printed Circuit Flex (PCF) and other Packages.
