J. Dumont, Did the problem start right after cleaning? If so, the temp sensor may have been damaged during cleaning. Jerry

Hi Greg, I'm with you on that one - yes, as engineers we should be able to come back at sales people who claim their products walk on water, but you do seem to have had an excessively unfair kicking recently.

Or do as we do and use Sharpie pens and document clock numbers right on to the board/panel. But as for the stamps I have used them at a previous place and they seemed to work good but only thing is I can't seem to remember where they got them from.

Colored paint pens by Abbeon are inexpensive and cannot be removed with things such as flux-off. They have a ton of colors and all it takes is half a second to touch each board. Remember, this will NOT eliminate or solve your defect problems(like m

We have used small hi temp labes, that are placed on our panels, boards before reflow. Each operator has a roll of labels with an assigned number. 4 operators, label 1, 2, 3 and 4. It worked well for us.

I was looking to see how others are handling conformal coating PCBs containing BGAs. We have looked at underfills, but none meet the reworkability we need.

I have seen the solder shoot out at least 4"-6" from both the leading and trailing edge when this happens. If the open pockets are real deep you may want to use a turbulent/chip wave for soldering, sometimes this leaves bridges however.

I'm looking to automate my PCB labeling. Anyone have any insight (especially first-hand users) into this type of system?

Mike, I have a used Computype machine that pulls labels from a printer and installs them on the pcb. I can send you pictures and copies of the specs from the manual if you like. Best regards, Clark

I have used the rectangle shapes and round shapes with no noticible difference. The idea is to design the pads to accept the same solder volume per component. Components over two size pads will favor the higher solder volume side during reflow.
