| Be consistant on: | 1 Keeping the coating material thinned. | 2 Using the same dipping motion on each board. Amen on thinning the coating, and you might also be concerned about the curing mechanism for the coating. Moisture-cured and 2 component

Various solder metal supplies sell pre-forms as loose individual shapes, usually donuts. The loose performs then are placed on the connector leads. If you have any volume at all, you would want to look at a �shake table� that would vibrate a batch of

arzucom, have you considered using trays to handle your boards in process and your handbuilds. This method is fast becoming the industry standard method for a large variety of reasons, specifically ESD as when the boards are in the tray your people

No, no. It's koscher to have thermal planes. You just need to: * Work with your fabricator to keep the layup balanced. * Relieve the plane so that it doesn't cause assembly problems. While probably not directly for your part, it gives a starting p

In short this guys are not well updated on the new technology of SPI. True, 3D IN LINE SPI is no longer a slow machine. Try checking some brand like Cyberoptics,Synapse imaging,SEIMENS,KOHYOUNG and many others...they can match the speed os some mount

Jim: I have limited knowledge, but here's what I know: 1. Yes, it's a standard process. In today's SMTNet, it's rarely mentioned, and few people reply to postings. 2. Nope. It's a "specialty" piece of equipment for most CEM's. Depending on you
