If you could measure and chart 3 variables in my process, what would they be? The boards that I produce are on panels that are 12up and 2x4 up. All boards are single sided paper base w/o plated thru holes. They are on scored panels that measure 7"

Good Morning everyone. Per repeated suggestions I have been reading back issues of SMT and Circuits Assembly magazines. I have just read an article concerning selective wave soldering which I understand is to be used when active SMTcomponents are a

To answer your question it was mentioned that allowing the boards to cool slightly between reflow and wash may help this case to eliminate thermal shock from immediately going into colder water straight out of the oven with no cooling. In looking at

Q1. After reflow some boards start producing bumps/bubbles which damage the internal layers causeing PCBs failed in Electrical-testing. How can I eradicate this problem from my assembling process? A1. Find a proper board supplier. Q2. If SMT compon

Do you have BEC (Board Error Correction) > on that machine, and if so, did they > give you the alignment plate for it? I don't know if we have BEC on the machine. I can't even search the 550 page manual that was finally sent to us in a pdf file

Good Morning Here are a few thoughts. When mfg large flex circuits you will need to fixture them to create a stable production environment. As such, the foot print fo the product grows. So you may require systems that can handle 20 inch width by 38 i

We do a lot of low volume prototypes and several boards that have have cut outs or fixtures that dont always reliably stop squarely at the in carrier (beveled corners). This sometimes results in a fid read error, because the fid wont be in the search
