I find 100 feeder slots of 16 mm width quite sufficient. If there are two feeder tables, each table is ~ 36� wide. Even slow machines can travel that distance in less then 1.5 seconds. If I further assume, that an optimized set up may save 30-40 % o

I was recently approached by a leading industry consultancy group and was asked, ..."if there have been any major advances or developments in the field of electronics production, what are they?" It got me to thinking, we've certainly witnessed some

Ah, the old contour wave. I don't really know how to adjust those to get correct backflow to reduce your solder volume. I need to ask why you are worried about this. Do you have a QC requirement in excess of IPC class3 wich allows for this joint t

We've had a few problems with printing a flex-rigid PWB, and I'm hoping some of you could throw some opinions/suggestions my way. Our PWB is about 8" x 11" divided into two parts (side A & B) by 2 wide flex cables. Each of these flex cables is ab

We believe your problem is caused by the mismatch in CTE of the material ised in your BGA. In fact, this "potato chipping" [where the corners curl-up] is present in all BGA. The issue is the matter of degree. [Mismatching CTE is how old thermostats

If you want to be able to put down every type of part, and fast, you better look at buying two machines. You did not say how much speed you need but in-line spindle machines rely on gang picks to be able to come anywhere close to rated speed. I have

Yes we do place "big and heavy" SMT DC/DC:s on most of our board's. Please tell us what brand it is or at least what the package look like?!? For instance we place a different numbers of "heavy" DC/DC converters (40x20mm & 45x25mm) that has the pick-

I think the main cause of this condition is #3 because both #1 and #2 never change from board to board, these are identical boards with identical BGA revisions. These BGA's (as stated before) are about 3 years old.. I don't believe they are lead free

Thanks! Well, the procedure in the book says to first calibrate the mech aligner with the beam sensor, but that exceeds the X travel. I guess you can just eyeball it off the nozzles and then use trial and error. While poking around on the machine
