| Hello Ya'll, | I've got what may be a silly question, but why does it seem so important to everybody that you have x-ray capability if you're thinking about doing BGA? | I know what most people will tell me; "Steve, that's a pretty silly qu

I have a hermetic package with 1 atm of Helium (5% vol.) and Argon (95%) inside. We have detected the helium leaks at 5*e-8 ccatm/sec. My question is what is the leaking rate of argon. Can anybody provide any insight or information to calculate the r

We are a small company that specializes in upgrading portable computers. We are now wanting to venture into Pentium upgrades which requires removal & resoldering of TCP - Tape Carrier Package CPUs. How is this done? We currently rework SMT without

I have run across reference to EIA-481 for specifications on Tape And Reel components for automatic placement and am looking for something similar that specifies standards or dimensions for IC Tubes or sticks. I am trying to make the vibatory feeder

How do these components come packaged? Bulk, Reel, Tray,.... Some of the work bench manufacturers have X-Y pick ups for manual assembly. These x-y pick ups should fit over an inspection conveyor. Sorry I am drawing a blank when it comes to manufactu

There is no doubt that we reflowed topside BGA on our wave solder machine. We run our wave pot at 450�F and that�s plenty hot enough to reflow solder on topside SMT components. When the solder balls on the BGA melt, the package is over 200�C, trust

Contact the fabricator of this part for their recommendations. There is about as many different approaches to soldering thermistors as there is thermistors. You imply that this is a SMT style package. If that is correct, it's curious that the comp
