Here's a question for you to mull over. I've got a PCB that is 4 millimeters thick, that's about 160thou of USA money if you like it that way. The question is IPC reg's for hole fill say it should be a min of 75% hole fill and 50% on ground planes. A

Dave, We haven't head issues with the material on Pcb's. The issue is now that the coating is coming off the solder builds up on the fingers. Front side brushes keep the front clean, but the back are a issue. The fingers have a "teflone"? type of c

We've talked about assembling on flex previously. Search the fine SMTnet Archives for background. Issues that come to mind [which is very risky, given that this Saturday morning and last night was at Jimbo's] are: * Use carriers that can flow thoug

Silly question, but, are TR blades 'exactly' the same size as MPM's and seat themselves in the holders just like MPM's? Also, different types of steel are harder (less flexable) than others. Are TR's the same? If harder (due to steel strength or coat

When I do a patent search, I find that most of the patents related to our business come out of Japan. I wonder, if in this country, government and business do enough to encourage employees and reward their ideas. For entrepreneurs a patent is quite

Does the machine come with manuals, training? - do you get a feeder setup jig with the sale, is there any spares to go with it, do you have any contacts for spares, what sort of maintenance is required - how often etc. did the previous owner do the m

On our last thing like that [5X5, 32, er 28?], we printed bumps on the QFN, but you can't do that, so there's no sense in tormenting you. Ideas that come to mind are: * Search around SMTnet for a paper by Chrys Shea on controlling dispense shots as

One thing to bear in mind when bar coding, make sure that the reel taken off and the new reel being put on is bar coded. What I have seen previously is that operators bar code the same reel twice, for them it is easier, but does will not always catc
