Arnoud, savez-vous ce qui ?
A lot is said both from Steve and from myself, but I begin to doubt we made
things clear for you. Why not simply do this (we use it):
ask the board supplier to do test bondings (tell them what wire, size,
wedge/ball etc you use) and send to you for evaluation. Could it be simpler?
Most board makers have collegues nearby with bonders, some have themselves.
Just that
Inge
