Hi Jon, Flip Chip is chosen as an interconnect approach when one needs improved performance (high pin count, high frequency, noise reduction or improved heat dissipation.Another driver is size...Flip Chip greatly reduces the area and therefore is cho

Do you bond with Al or gold wire? What happens if the Ni is over 150 microinches? Thickness of nickel is one those things that we have not been consistent with. The industry seems to pretty much universally call for 100-200 microinches. Our old board

Is your IMC purple? [The sure way to tell if you have the 'purple plague'.] Where does the failure occur? * At pad / wire bond * Up wire from the bond Tell us about the aluminum pad. * What is the plating specification? Is that what you actually r

Well, I can't speak for them falling off later on, as that's not when I see them, and they are passing their wire pull tests after bonding. What I am seeing is electrical opens during testing, and these opens coincide with the Au/Al bonded points. Th

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

Hello All, I am PhD student at polytechnique Montreal. We have a CQFP44 packages and Dies of 51um pad pitch (22nm FDSOI tech) that I need to bond myself at the university using ASM Eagle Xtreme gold wire bonder in the university. we need to perform b
