We are currently having our board assembly house use a quick drying glue
to secure a 30AWG wire to the pcb for a modification. We are finding
the glue can cause electrical problems (not all the time) if it is
in the leads of FINE PITCH surface mount devices. This is confirmed
when the glue is removed. There is the telltale white residue on the
glue indicating the glue is applied first and the accelerater applied
second. Something I've done myself. It's my understanding that the
accelerator should applied first and the glue second. There are no
controlled impedence issues and comparativley low frequency of
1 to 32 MHz digital signals.
1. Has anyone had electrical problems with glue in the leads of
fine pitch devices?
2. Can the glue be conductive for at least fine pitch devices?
I've seen this glue used tons of times without this effect.
Thanks in advance.
