One of our instruments has a high impedance front-end. We: * Passed functional test in the environmentally controlled shop. * Failed test, on the same unit, while carrying it to burn-in chambers in an uncontrolled part of the plant. Solder flux resi

Lead forming can provide retention during wave soldering. There is the simple offset method, the dimple and compound forms. All of these are outlined in IPC-AJ-820A. It would probably require automated lead forming equipment using special dies. GPD m

Hi FengAng, Sorry about the misunderstanding - last time I was out there all of the front end SMT equipment was very good, but the final assembly of the phones into cases was being undertaken by hand, whereas in Europe we were seeing a lot of automa

Try the IPC-254x CAMX standards (webstds.ipc.org, no www prefix!). They define a set of generic and process-specific XML messages for equipment to send out all sorts of process-related events. I know there are standardized messages for print, dispens
