Eric: I�ll pass on the uV and ammonia, also. Thoughts are: 1 You�re correct that the temperature/humidity mix can be a big driver to latex peelable solder mask cure time, but don�t overlook material thickness. Dispensers put material in a very th

We have been experiencing intermittent problems with the solder masking bubbling up from the bottom side of the board, after wave soldering. Our board fabricator claims that none of his other customers are experiencing this problem, and that it is pr

Mike, I don't feel that I am putting too much emphasis on the EPA certification. If it wasn't for the EPA, I would still be using freon in my old degreaser and would not have needed to change chemistries 3 times in 5 years. Why fight the EPA if th

Mydata vs Siplace

Electronics Forum | Fri Apr 26 08:38:14 EDT 2002 | ian

We have had Mydata for eight years and Siplace for six. We have found that the Siemens is much more accurate and faster than the Mydata (about four times quicker). Although the Mydata is more friendly regarding the software, if the upfront preparator
