This is a question about complying with J-STD-001 solderability testing. Do any of you have your vendors certify that the components and PCB's that you buy from them comply with the solderabilty requirements spelled out in the -002 and -003, in lieu

Earl, As always, I am interested in what you have to say, but I am still a little vague on your application of ANSI Y14.5 as it relates to the manufacturability of an assembled printed circuit board. Are you implying that component placement coordina

We have been running a 2060 (along with a 2050) for about a year. Great machine; good follow up to the 700 series, of which we run several variants. We have a 2 shift, 5 day operation with 7 changeovers/shift. We've minimized downtime by building fee

It takes time for the moisture to penetrate into the body. I think the 5 years of ambient would be more the culprit than washing the boards. Especially since you are baking them after wash. Get a few of the ICs and put them loose on a board and put
