Doug, Have you tried running the boards at an angle to the wave of between 15 - 30 degree's ? I've done this on a few boards to eliminate short's and I believe it will work on your problem very sucessfully. Best thing to do is get your wave solder c

| I am building a board with T1/34 LED's in a 10X10 array there are 12 arrays in a panel. The LED's are body to body in the array, .1 spaced. The LEDS have been autoinserted on a Universal RAD III, so they are cut and clinched. The trouble I am havin

Define "expired" though... 1 week? 6 weeks? 1 month? 6 months? Unrefrigerated life is generally 30 days. If paste has been stored refrigerated at manufacturer recommended temperatures, what would you guys do, like say, if you owned your own shop

You weren�t clear but I assume the problem is not widely distributed and affects only a few parts on each board. Do this trick: * Cut a ~1� piece of fairly serious wire, like 18 or 12 AWG. * Strip the insulation. * Gear-up with gloves, glasses, and

Boca, Dave Sorry, but I cannot let this go. I'll go along with you that, at the time that the Montreal Protocol was initially signed (September 1987), there was no scientific proof that CFCs etc. were causing ozone depletion. There was, however, ve
