Can someone please tell me where I might find detailed information on the processing of a double-sided flex circuitry design. I am looking for specifics such as methods of fixturing,printing,placing and reflowing.Things to keep in mind when processin

Shawn: You're correct most solder preform manufactures don't want to sell preforms without skinning you alive for tooling charges!!! Considering alternatives, can you print or dispense paste? It would be mucho cheaper. We've talked about using pa

Try tinning pads with a high pH water soluble flux like Kester 2331-ZX or Alpha Metals 3355-HB is what we use. It will remove the contamination quick;y without having to scrape with a blade. If you have a large number of bare boards you can run them
