Hello,

Has anyone experienced bleed-out of conductive adhesives after dispensing?

We have seen resin from the conductive adhesive contaminate areas around the pad. The contamination spreads to nearby areas and makes it very difficult to wire bond onto. On a different substrate, the same adhesive yields much less or no bleed-out.

What are the reasons behind this behaviour? What can one do about it??
