I actually wrote a program that looked just like the CSM66/84 system. I wrote it so we could train our staff offline without having to interrupt production. It did everything just like the real program (including the initial RAM load.) You would use

Alot of QM's and QE's are typically failed Engineers who lack common sense. They don't understand that measuring in DPMO's (versus DPU's) "normalizes" your data for Printed Circuit Board Assemblies (PCBA's) so that if you have 10 defects on a PCBA t

Ewwww metal mini stencils? Try http://www.circuitmedic.com/products/stencils.shtml We use their flextac stencils all the time and they work perfect. You can get a couple uses out of each of them if youre careful too. Just line it up under a scope and

I just purchased some PACE ST-25 systems for basic soldering and they work great. It was a deal at $155 each and they heat up FAST! Tips are around $6 each so the whole system is affordable. A step up for rework jobs would be the Metcal MX systems.

Thanks for your reply! Have you tested the torque meter yourself? I have asked our supplyer if they had any but the answer I got was that they should check with Fuji, and that semes to be a slow process... We do mouthly mainteness on our highspeed fe

"Although some lead-free pastes performed adequately and newer pastes work better than earlier formulations, this detailed experiment confirmed that tin/lead solder pastes wet back to PCB pads better than lead-free solder pastes. Therefore, a more ac

I use a Liberty Bandit brand hot air rework station and have placed 676 ball BGA's with very few problems. All of our products are now RoHs. They have good product support and easy to use directions. I think this unit runs about 15,000 or so. Good lu

Hi Brand new here and I really need some help on a problem with a Philips CSM84V. We have programs loaded and they worked fine awhile ago. When we hit run now, the conveyor starts running without the board being present (says "transporting pcb" not w
