I am looking for a barcode machine/printer which will print barcode directly on printed circuit boards with non transferable white ink. This has to be done before PCB assembly. Any help will be appreciated. Please reply directly to my E-mail. S

OK Sergey, looks like no one wants to take this on. I will give it a shot and maybe others will add their 2 cents. The answer depends on what you want to inspect. X-ray inspection is based on the X-ray absorption properties of the materials in th

Comments are: * A good looking solder ball does not necessarily mean that you have a good solder connection between the ball and the pad. We've all seen a bright and shiney solder ball on the floor, but that doesn't mean there's a good metalurgical

Hello Glenn, thanks a lot for your response. The company I work for is launching LEDs production this year. We'll need to do a number of the environmental tests in our quality control laboratory. So the application for SAM and Xray systems is inspect

X-ray is probably more useful in the grand scheme of things. SAM will, like Glenn said, pick up delams in components especially at internal interfaces. X-ray will only pick up a defect like this if it's perpendicular to the delam, very difficult.

Dear Park Kyung Sam, your problem can be solved asking to your PCB supplier to cover all the via holes with solder mask before the HAL. Usually this is possible and doesn't produce extra cost. Vincenzo Longobardo vinlong@tin.it
