Plasma cleaning is used extensively to clean surfaces prior to wire bonding.

Which is it: * Wire bonds don't stick when bonded * Wire bonds fall off, or break during service

Does anybody out there have experience building electronics assemblies with DCA (Direct Chip Attach - bare die onto PCB) and wire bonding? - What Die Bonder/Dispensing Machines are recommended? - What brand conductive epoxy were used to attach die?

Hi all, Recently, we are trying to do wire bonding between a 75 * 75 um pad on a chip and substrate with 150 um height difference, but when completing wire bonding and the wire bonds on pad and substrate, the pad will get out of the chip easily

Questions are: * Is the problem 'wire bonds that don't stick' or 'wire bonds that fall or break off later'? * What materials are you working with? * What is your working time after plasma clean? * What does surface analysis tell you about surface con

Electroplated nickel and electroplated gold is the more �traditional� finish for aluminum wire bonding. That surface was an extension of gold thermosonic wire bonding that requires a thick [50 thou min] gold surface. For years fabricators recommend

Wire bonds don't stick when bonded * Check pull and shear strength. * Depending on point of failure, review parameters. * Listen during bonding, if there is a high pitch buzz, there is vibration in the system somewhere, "seek and destroy". * Get the
