Gary: According to what I was try to say, you have read me correctly. NOW ... I would not pay much attention to my 100�C delta T babbling. It is in our work instruction for setting-up the wave, but no one pays attention to it. And I, nor anyone e

I belive I once saw a picture of a Delta-T. It was in a very old Popular Science magazine. Some yahoo from Ohio wanted to put wings on his ol' tin lizzy. He also had some elaborate plans to convert his flat head V-8 to run off corn likker. I say chuc

It has been our experience that the problem you have discribed was not solder process related. We had two such instances in the past and both were component related. The first case involved a PLCC28 that failed test. Reflowing the solder seemed to co

Brian, The SRT FPD-W is an older unit that has been successful for a long time. We have used it at BEST with good results. The SRT FPD-W is a very good machine for the uses you mentioned except possibly for the BGAs. I have seen some used for BGA

Bill, Are you recommending the heat range of 95-100F (35-38C)to clean stencils with the Smart Sonic using the 440-RT SMT Detergent? The reason I am asking is were are looking at potentially the Model 2003 to clean our paste stencils and our adhesive
