That you can get good solder flow when hand soldering seems to indicate that the temperature of your solder pot is too low. Still, I'm uneasy that you see gold on the pads after passing the board across the solder pot. Gold is so thin with ENIG. So

Hello: We have used our Phillips Topaz on a number of volume jobs and been very pleased. A while ago it became apparent that the vision LED's were growing dimmer as evidenced by having to adjust light intensities upward for various components in so

Checksum will work if all your doing is analog/passive testing. Checksum systems do not have digital test capability. I would recommend a Teradyne z18xx system. We use 8 of them in our plant and have been for years. Used, these systems range from

Looks like you have a carbon black process that isn't quite plating to completion, pin prick size holes have remained in the plating. When dipped in an etchant (ie any acid or H2O) the holes grow and they leak carbon. This may be more of a problem th

Hi, I have a QUAD 4C mk2. I taught pickups and places from HHT. If I test them individually (RUN STEP PICK/PLACE etc...) before building the sequence, everything runs ok. After the sequence was built, everything goes wrong. Every PICK or PLACE ends i
