I agree with Sai regarding re-sale. It's night and day with Fuji vs. Philips. You can't imagine how cheap FCM-2's are going for these days. I've got a 2000 model with 200 hours on it (basically a new machine) and over 100 feeders available for very l

I really don't think so. Most of the time copy is much better than the original. For the durabilities, Philips can't compare with the Fuji, Resale vaule, productivities. Fuji is the best. Philips has many original; CD, SACD, Plasma Display. But the J

You can try using the brand-solvent "Genesolv 2004" in conjunction with a degreaser machine(source for own machine type?). this all helps to clean off the NC flux. we used it all integrated together, to clean a satellite modular card. reason we ha

If the solder balls are next to your discretes, you should consider a homeplate design on you stencil apertures. THe only other time we have seen soler balls is due to the raw card. If the vias are not plugged by the solder mask, solder and air can g

Hello! We are using a Triadspectrum (www.triadspectrum.com) TURBOCATS I memory tester, it is good, but we have faced with problems, such as: a poor contact between memory module and test cartridge,absence of the power-on button, every time we need p

Currently in our facility we store used and discarded flux residues from the wave solder machines in 50 gallon drums. These drums are picked up and disposed of by an outside contractor. During a recent audit we were cited for not having the drums

I do know in our factory (7 years ago) we were required to ground 55Gal. drums. But only when they were on drum/barrel dollies. The fear was the nylon (plastic wheels) could cause static electricity and gorounding helped to prevet this. I never quest

Francis, The problem with shorter solder lands is you may have a problem getting good heal fillets. In the flash products I built the PCBA was inserted into a plastic shell and then we did an epoxy encapsulation using a Camalot machine. Toshiba, Sams

Francis, The potting encapsulation process was in the mfg. of flash-disk devices built on a DIP formfactor. Compact flash do not normally get potted. Ultrasonic welding or snap-togther is methods for closing the compact flash housing. The potting mat

I'm trying to get a better understanding of the cooking process of pcb's. The use of nitrogen in reflow and wave ovens. Seems to have a wide margin of acceptance as a standard gas to prevent oxidation of metals in the board. Has any one heard or us
