It's amazing how many parts Castle uses that we also use at work. We have a lot of problems with the Tant. caps shorting out. Next the Electrolytics will start pooching out.

We have a switching power supply that is made by another manufacturer and after 6 months to 2 years they fail. They are all low ESR. Jamicon and Hermei are the ones we have the most problems with, and switched to Nicholsen(sp) and stopped having problems. There are 3 470 uf 1 1000 uf and a 2200 uf that always fail at the same time. Although we still have a bunch still come in for repair that used the old caps before we found the problem. In the last 2 years we have yet to have a repaired board come back (with a problem), at least I don't consider a blown fuse with the spare right on the board a problem since it fuses the output of the power supply itself, so if it's blown it's another card and it's usually a Tant. cap or one of the other surface mount caps that are shorted.
