Johanson Dielectrics receives a lot of requests from our customers to help them with cracking issues. One customer had cracking at a rate of 16% on 1206 size high voltage capacitors during their process. The top picture of Figure 3 shows a clear mechanical crack with a 45 degree angle at the termination solder pad interface. Repopulating the same board with PolyTerm® capacitors showed no cracking failures. The bottom picture of Figure 3 shows how PolyTerm® Capacitors solved these problems. No cracking was exhibited on any of the PolyTerm® capacitors during the customer assembly process.
