Kurt: Lots of choices, not many of them good, yano. 1 So LPI has taken over the market pretty nearly 100%, but it won't "tent" reliably, because it is not very viscous when applied and drops into the hole. So then, tenting/plugging with LPI is bad

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

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
