I need a good chuck, new or used, for a QUAD 100 pick and place. The chuck size is 00-001XG. The one I have has worn fingers, bushings, and leaks air around the nozzle. How difficult are these to rebuild properly? I would appreciate hearing from a

HI, just my 0,00001 cents Which preheat system does your wave solder has? for instance ? - IR ? - Bottom only ? - IR + Forced Air ? (bottom) - IR + Forced Air (bottom) IR top ? PCB thickness ? Appropriate preheat is important when looking to f

Will A Few Failed Solder Joints Make Me RoHS Non Compliant?

If you are in standard specs, don't even mention it. THe RoHS thing in electronics becomes more and more annoying. I haven;t seen people taking out PCBs from their electronic devices and start to chew them. So it was ok to use gas with Lead for deca

You see, if you can optimize your product setup that will be the best. Back in the days, engineers used only standard values. For resistors for example I used to build boards having 100, 330, 470, 1k, 3.3k.....Sometimes that means you might end up wi

In order to kiss off the components with an air blow, there are two times to consider: 1. reaction time of the solenoid ( to shut off the vacuum and turn on the air ), 5-10 ms 2. time required to fill up an air hose, which leads to the nozzle. Assumi

Ian, First, I baked the parts at 125C for 48 hours and check the weight Second, I soaked the parts above 30C and 60% for 96 hours and check the weight Calculate the weight gain, suppose only moisture add to the parts during soaking, say a Third, dry

We/ve never heard of "glass wicking failure" in regards to board fab. Boat fab, yes. Look here: http://www.boatdesign.net/forums/showthread.php?t=13321 Barrel cracking appears after thermal stress during soldering, because epoxy expands in the "z"

I have done some revision work on the UFOS format. But in my research I found that the format has a bit of variation in it on my old YM6021 the component field has 6 digits and the later YM series it has 8, also does the designator comment crash your
