People have made good comments. Additional points are: * Your bridging is probably being caused by one or more of the following: [1] printing too much paste, [2] smearing the paste during placement or subsequent handling, or [3] paste slump during t

Hi everybody, This is a simple posting to initiate a discussion on different ways to troubleshoot, improve, and control the Stencil Printing Process SPP in SMT manufacturing. There are many SPC, ANOVA and other analysis techniques that provide insi

We've all been soldering Pb free parts for a couple decades. All your surface mount capacitors have probably had a Sn finish for years. Whenever one of our parts with a SnPb finish converts for Pb free we have the manufacturing site do a small buil

You are correct that hand soldering ceramic capacitors often causes them to crack. They do not take thermal shock well. You might be able to reduce the amount of cracking by following the rework repair guidelines discussed in the fine SMTnet Archiv
