For soldered areas, we like to keep gold thickness substantially below the maximum you propose. Search the fine SMTnet Archives for our discussions on the topic of acceptable levels of gold with solder connections. Let�s fix this �no one seems be s

5uin. Your nickel thickness is fine. Although if you wanted to trade costs, consider giving-up nickel to 150uin thickness, while increasing the gold thickness. Gold over electroless nickel creates brittle joints because of phosphorous in the nicke

Finer pitch: Wedge bonding can be designed and manufactured to very small dimensions, down to 50 mm pitch. Processing speed: Machine rotational movements make the overall speed of the wedge bonding process less than thermosonic ball bonding. Alumin

I have been reading a good deal about IMC (purple plague in particular) in gold wire/aluminum pad wire bonds. My company uses ultrasonic wedge bonding, and for the most part all of our bonding is gold/gold, however we have one particulr part that has
