> 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.

Nickel corrosion in ENIG and ENEPIG is occasionally reported; when encountered at assembly it manifests as soldering failures in ENIG and wire bond lifts in ENEPIG. Although not common, it can be highly disruptive, resulting in missed deliver schedules, supply chain disruption, failure analysis investigations, and liability - all very costly.

As a surface finish for PCBs, Electroless Nickel/Electroless Palladium/Immersion Gold (ENEPIG) was selected over Electroless Nickel/Immersion Gold (ENIG) for CMOS image sensor applications with both surface mount technology (SMT) and gold ball bonding processes in mind based on the research available on-line. Challenges in the wire bonding process on ENEPIG with regards to bondability and other plating related issues are summarized.
