I believe you need some sort of "flat top" for this connector. I have ordered special "tops" for connectors we have placed in the past, the top is simply removed before any item is plugged into it. This also protects the connector after the board i

Does it have to be made out of plastic? Wouldn't some stock aluminum plate with milled out pockets work just as well? Would the aluminum offer the same, better, or worse ESD protection?

I have recently encountered a new pcb design with a very high density of components on either side of the pcb. One of the suggested "fixes" is to use the smt pads as vias i.e. the via will be drilled thorough the centre of the smt pad. My concern i

KA, Joshua makes a good point. A wave solder fixture will allow you to process your double-sided boards without having to add the epoxy step. The one time fixed cost of a fixture is quickly offset by the time that you save by not gluing your SMT.

I have a need to send some Engineers to intro SMT classes. I have found two avenues: 1)ACI (which is to high level!) 2)Cookson CPS which is more in line with intro to SMT process. Are there other that are on re-occurring timelines?

Can anyone tell me what parts on the pwb should be protected by the conformal coating, and what parts can be free of the coating (such as the areas without components, traces, brides lands)? we were follow MIL standard 2000 and IPC-A-610 class 3. Tha

Has anyone taken any classes in SMT assembly that can highly recommend? We are looking for a class to send an engineer where there would be hands-on time on a printer, pick and place, oven profiling etc,,,, BWET

I would like to ask you for help. We use mixed technology and we need to protect SMT components in double Wave. Currently we use the carrier for protection of this component. In this case this procces is not possible to use it due to gap between SMT
