As I understand, you are wire bond gold wire to gold pad, where the substrate has good bond strength, but the die does not. If bond quality is good, and then drops off rapidly, then it's probably something to do with contamination within the system

You didn�t identify the type of tape you use, but Kapton or similar tape is not an effective method for attaching thermocouples. Search the fine SMTnet Archives for alternatives and comparison of methods. Two methods for mechanically attaching ther

Did the tray changer use to work on this machine? was it ever disabled and uncoupled from the machine? If you have an old data disk or backup disk of the machine try restoring to that. There is also a jumper inside the wiring harness to include the

We're not familiar with the AUG5 from Taiyo. [It doesn't show on their US site.] Is it liquid photoimageable? Printed solder masks are more likely to bleed. But you wouldn't have any solderability with bleed. Your plating seems acceptable [if th
