Dear members, I am promoting mecseal finish for doubleside SMD jobs to our customers. One customer pointed out the following problem. Two mounting holes(pth) is taped during wawesoldering and subsequently brackets are fixed.He needs to ground the bracket and nut should make electrical contact with land surrounding the fixingholes.Since the fixing holes are covered with tape and subsequently tape is removed meseal is not removed in that part.This will lead to no electrical contact between the nut and the hole including land surrounding Any suggestion to over come this problem please.May be some design alternative to overcome this problem Since OSP enteck etc. are in existence for quitesometime I think someone might have this problem and overcome also. Thanks in advance for any response R.Srinivasan Engineering mgr Likom PCB SDN BHD Malacca Malaysia E-mail:[log in to unmask]
