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
