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

Consider buying a taping machine. At the last contract mfg. I worked I bought a used V-Tek TM30 manual taping machine. It was a tremendous asset. Start saving your embossed tape and reels now so you will build up a stock. Hopefully your placement mac

The previous entry is a very good point. After dealing with quad/tyco I have such a horrible taste in my mouth from thier lack of professionalism and dishonesty, that I wouldn't buy a tyco product if they paid me to take it. If I were a betting man,
