I assuming that you already have checked the fuses? Also, check all the power: +5V, +12V, +-24V, etc. We had to change our PSU once, after a major power-drop due to a thunderstorm. But you should be ok if you can pinpoint what type of voltage you are

SMTNetters, I have a product coming down the pipeline that we'd like to make pure double sided reflow, it'll be RoHS product, and the hope is... we'll be able to solder the thru-hole stuff by screen printing solder paste and reflow soldering. Anybo

What year is your machine and what year is your Electric Drawing? My machine is 1989 and so is my drawing. I do not have a SIP-1750 drawing. The IP went through several changes during its production so your machine may not match mine. The CON I/F

Design rule for vias

It's worse than just using the test equipment manufacturer guidelines. Along with that, you have to deal with each of the test fixture fabricators' preferences as well. What this boils down to is a negotiation with the test engineering group as to w
