Interesting! Several years back I had a through hole machine which was purchased through a broker. I needed a replacment part and the machine manual have a part number which I found out as superseded by a new part number. Upon calling the QEM technic

Hello Sean, We are currently using a Pin in Paste process to mount some through hole relays. This particular board has 72 relays per. We have cut the stencil to overprint the hole. By putting a small amount of solder in the hole to flux the lead, th

HELLO, Do anybody know if is existing an empirical rule that can show me how many amps can carry a plated through hole with a diameter of x.xx millimeters? Is there a formula depending on X.XX value that could help me to make such calculations? How

There are a variety of options without knowing what kind of components are on the bottom side (C's and R's 0805 or 0603 or 0402) you are talking about consider the following Option 1 If bottom side has only Caps, resistors and/or Soic's then... Top s
