OSP adhesion

Electronics Forum | Tue Nov 10 13:31:00 EST 2009 | chris0595

When applying the ECCOBOND E3503-1 thermal adhesive to attach a HB-LED to the slug area of a MCPCB, should the OSP coating on the slug area first be removed? I have heard that OSP coatings have poor adhesion properties so I'm wondering how to do this
