Hi Sam, I have a feeling that what you're trying to communicate is that your DPAK's are skewing off the pad during reflow. This is caused by a thermal "mismatch" where the solder paste on one side of the DPAK becomes molten before the other, then th

Electronic digital methods of determining unsoldered leads/pins Unsoldered lead or pins in a PCB or any other electronic components leads to open circuits or faulty electrical connections thus the device does not operate. Typical inspection method

SWAG does make a good point. The tool he is talking about is located on setup page 1 in the vision box and is labeled FP Mode (Fine Pitch) mode. BY default the setting is "0" this means that once the machine is put into auto mode the camera or visio

The answer is CyberOptics. Buy Viscom SPI and you are already buying "CyberOptics Inside". Koh Young is far too expensive these days for comparable systems and Parmi is still an "Up and Comer" with a short track history leaving most of the long ter

You are correct about KY having the lions share of 3D AOI in the industry. They were 2-3 years ahead of everyone else to entry, but the gap is closing quickly as the overall capability of KY does not justify their higher price. On the SPI front, Cyb

Hi, New to this forum. I am an engineer assigned to resolve a quality issue on our production line. It seems that we have been getting small droplets of flux on our boards after the reflow process. Occasionally, they land on a board to board conne

It's well documented in higher power semiconductors where thermal interface materials are used, such as SIL pads, thermal grease etc. There are a couple of papers on the effects of voiding on MOSFET performance, but I haven't got around to reading
