During temperature cycling we have determined that the conformal coating wicking underneath our BGAs has caused fractures in our solder balls. One proposed solution is to run an RTV dam around the parameter of the BGA to prevent the CC from wicking u

In general, if the process has been consistent for a period of time, then one should look at any new variables in the process. Therefore...the supposition that there's a bad lot of components is a very good one. Did Yageo offer any possible explana

. Although it may not be seen at this time, the ceramic will fracture when exposed to heat cycles. Solder paste, Tin/Lead or Lead-Free. Lead-Free is more brittle and the stress relief will be absorbed by the component causing it to crack
