Gary, Here goes for what it is worth. We store all of our SM reels in the SM area in proper trolleys (Mossmann-Tebbs types). They are stored by part number, which sets them into Capacitors by value and size. Resistors the same and so on with induc

Luckily for me, if the part were soldered and on the board prior to any processing, I will still be able to build it. I am currently experimenting with screen printing a high temp paste, hand inserting the part (even Chad hasn't come up with an econ

WE are using press fit connnectors on a range of boards, one of which is posing me a few process questions . The Machine is a fully automatic machine. The problem is intermittent and I can't seem to put a finger on it. An array of connectors ( consi

Adam, The most common cause for this problem is a variation in the plating thickness of the through holes, particularly if they are Sn/Pb solder levelled PCB's. Most pressfit connectors require a fairly tight control on the diameter of the holes to

We have seen this problem several times. It always goes back to pad solderability, very seldom does it have anything to do with ball size. If there is no evidence of wetting on that pad, but all of the other pads did solder, you need to ask yourself

John Ooooo, leave it to me to miss THOSE customers!!! Darn, as you can see from my response, I was thinking ... well let's just leave it at that. YESSS, let's use as much capacity of the heavily loaded part of the shop and not use available capac

I don't get the no-lead thing, but it's good marketing so, whose to fight it? Yano? If I didn't get the no-lead thing, I'm double clueless about bromine. That is until I read a recent (8/00) article in PCFAB magazine. I away thought of bromine as

John, I hope your figures or numbers are part of your SPC process. Our management loves this stuff. I think the production line, world class or not would reflect the attitude of the people working on it(keep that between you and me) management does
