Aluminum wire bonding on ENEPIG plated PCB | 9 September, 2013

Hi,

We are having issues aluminum wirebonding on ENEPIG plated PCB by a too low pull force and or having lifts (1% range).

Could any body advice how to solve this problem?

Is there a special wire bond grade required? How to best clean contaminants by the SMT vendor?

Thank you in advance

I don't know, but here is a link to a paper from the fine SMTnet Technical Library on a similar topic: http://www.smtnet.com/library/files/upload/Wire-Bonding-and-Soldering-on-Enepig.pdf

Contact the authors and ask for their advice and help.

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