I, too, have finished qualifying the Amtech paste for a dispensing application. We will be experimenting with the component soldering/stencil printing next. The stuff has proven to provide the best of both the no-clean/low solids and water washable

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

Thank you Pavel for your interesting. Speaking on tact time ( machine speed per Board ), our Universal machines are too quick thank DEK machine, that's why I am thinking to add another machine in Glue process. FYI, we are working on Satellite receive

This solution is not as complicated as you might have thought. T-conveyor connected machines are widely used for applications requiring high material deposition throughput. This solution is made of: 1. Two independent screen printers 2. Two line loa

ECD, KIC, or any mfgr. of thermal profiling devices will charge a premium for "simple stuff". For example, ECD charges a grand for their "flux-o-meter", which is just a PCB with a hole pattern, a pallet, and pH-sensitive paper. You can easily ma

Has your board house reviewed the PCB layer stack? Make sure that the layers are balanced in copper weight, etc? Have you tried pre-baking the boards? We just had an issue with some boards warping that have never warped before for us. It happened
