Earl, et al, Boy things get old and cold around here fast. I promised more detail on my capactior problem and I thought I could drop something completely different in the same message and tell a tale of solder balls. First the caps. We still have

We roll ours up, fingers and all, and soak them for about an hour in a solution of water and DOMINATE (heavy duty degreaser) you can order from Grainger. They come out looking brand new every time!

a more general solution is have you done some cleanning in the vaccumm for the nozzles? change the filters or filter?

Insure your rinses are only 25 to 30-seconds each. Also there are options for cleaning solutions from Kyzen that are safer on AL and do not require dosing of any additional inhibitors.

Hi, I curently have an interesting challenge. But I don't have all the knowledge to solve it. One of our boards is used in RF applications. We noticed that the No-Clean flux residue makes interferences in the RF signal. Removing the flux residue so

Just my opinion but it look's like your doing a great job. i would try another paste. I'm somewhat lucky that we get to use OA's. If your stuck using the no-cleans they are so tempermental. (The nitrogen is making up for the poor paste) Your de-wetti

This is a question regarding soldermask between pins of fine pitch devices. The majority of our production designs end up with at least 2-3 mils of copper thickness on the external layers due to blind vias, wrap plating requirements, etc. Our curre

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
