Hi Pete, The boards are HASL. The frequency is random. The solder balls are randomly deposited along the path of the select wave, not always along the component bodies. We are very careful regarding handling. There could have been contamination on s

We are getting broken traces in PCBAs, any idea why. In addition, only few of the boards show this problem, hence I don't think it is an issue with the board manufacturer. thanks, SS

I personaly use the SMT6000 and STM8000 from OK industries for small quantiy and prototype boards. The board does need to be removed from the conveyer but these machines work well for the volume I do.

Has anybody expierianced solderability issues on electroless nickel boards that do not have gold immersion? We recently tried to process boards of this type, and I may as well have been trying to reflow on plastic. Any ideas?

Here's the bet. I'll bet the size [ie, length, width, thickness, etc] of the boards remain the same. It's the size of the copper features on the board that is changing. Right? Right?

What are the industry standards for eutectic solder-paste in conjunction with the life span of solder-paste. What is the recommended duration of solder-paste on a printed circuit board. Example: You print a board, how long can it sit before runnin

Peter, QC-calc: Verifying vision accuracy of your printer with calibration stencil and hundreds of repeats. If your boards are large and specially if you have finepitch parts on them you will find usefully to use QC-calc to measure board stretch/sh

Is there a steadfast rule of thumb for a good solder joint on an Enig Gold board. I come across this number 217C when discussing BGA profiles. Is this a published number? I sure could use a reference. Anybody feedback is appreciated.
