Hi All I want to carry out some stress measurements on pcb's to analyse the weakest areas at various assembly and test processes. I can use the latest technology in software to model the situations, but I'd much rather use a quicker method. What I had in mind was some kind of spray adhesive/lacquer which has brittle properties, thus under stress will crack and be visible under scopes or UV light. Can anyone help out with the name of supplier of this type of material and has anyone conducted similar tests. Thanks in advance Ian ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
