Hello,

Hoping for some help, we have Hesse BJ820 wirebond machine and after changing to new spool of wire the wire snaps after first bond. Anyone have any idea ? Wire is in date and no change in machine setup, just change spool of wire.

Where is the break occurring?

What kind of wire are you using?

What type of bonds are you making?
