I am looking for a specification required for printing 01005 size chip. Does anybody know the solder paste deposition accuracy and alignment accuracy required for printing 01005 chip? And currently which machine can print 01005? If somebody knows

jagman, take a hard look at a capacitor under the high mag microscope before you start assembling it.. I remembering seeing cracks even before the assembly. apparently all chip capacitors have crack at the intersection between the capacitor head and

Our company is assembly flip chip on flex, we have new design of flip chip which die temperature will increase until 145 degree C after test run the end product, however the Tg,glass transition temperature is 148. Will this case causing any reliabil

For chip components it is very hard to identify specially the capacitors. You could get sample of each chip manufacture and compare the color. This is very labor intensive task. I suggest to sort by value ( capacitance, resistance) than by manufac

2 waves is correct. While running the glass test panel over the chip wave (1st wave) you can see gaps due to the turbulance. What I did find was the gap of the chip wave was not closing up enough so I adjusted this which made it better. What is the p

We noticed unsufficient soldering on some 0805 chips located between pins from a plastic bloc connector . All chips are soldered with 45� angle. Flux quantity , preheating , contact time and PCB quality was checked. Do you know any international stan

I just got done analyzing an old piece of gear with relabeled parts. We had a schematic of the boards, with no info other than the OEM's part numbers and the way the chips were interconnected. It took me no more than 15 minutes with a couple databo
