There are some common reason for capacitor cracking on my web page if you want to have a look. The document can be downloaded for your reference. | Earl, et al, | Boy things get old and cold around here fast. I promised more detail on my capactior

I have used one (actually 2) of these machines. The upside is you can point to the print-out and tell your customers that you do test for cleanliness, and you pass. The reality of this test is that it tests for exactly 1 type of contamination. The

Most white papers, like this one http://members.ipc.org/ipclogin/ipcmembers/IPC/Route/0706/0706techpaper.pdf, have written that lead contamination in a lead-free solder joint leads to all sorts of reliability problems. Consensus is that, if the cont

We are trying to establish requirements and process controls for completed, cleaned SMT assemblies. We have problems with our high impedance circuits (100 meg ohms) being affected by residue. Some boards require additional cleaning cycles to remove

I'd love to get to the point that I could discuss the impact of flux on dross formation. Until then, I fight with proper solder pot temperature, maintaining enough pump speed, and solder contaminants.

OK. Point taken, lets keep this simple then, how about just the issue of under cured solder resist? Any body else encountered such issues. Just feedback, 'cause its something that just seems to have been highlighted to me. Thanks.

It might be easier to answer what we haven�t seen. In today�s economy everyone is looking for a deal. Just remember "there is no sex in the Champaign Room"
