KRIKIES! If that wasn't a sales pitch, I don't know whut was, me lad. Optimizer is good for DoE's and process characterization, but no substitute for the artform that is wave soldering. When me lads here in Purchasing get PCB's from all over the w

Daniel, We'd recommend MyData's as good low foot print, short quantity machines. They have a good level of flexibility for the price and operation. Considering what you've described, an older used TP9 would suit you. I'll caution you, though, tha

Small waves are fine, biggest problem is the little to no preheat length. This is reason that complex boards cannot be soldered without defects. They also do not handle thick PCBas very well either because of same issue. Most of these "benchtops"

Thank you to Dave and Scott!! What I'm delaing with is mass production test for small memory cards in volume! The reason I choose Non-operating temperature cycling is so that I can deal with volume. I can throw in quite a few memory cards in chambe

We have carriers that we use in wave flow solderers that are machined specifically for each board out of ESD composite. I was wondering if anyone knows about lead contamination of this material and the cleaning of composite? I know that it is a p

Hey that was me way back! Anyways, use Dow 3140 (self leveling) or Dow 3145 (peanut butter consistency) and call it a day. No out gassing/acidic properties. 3140 also contains a UV tracer for black light inspection. Any tall caps should be epoxied if

I've done some pretty scary cross-sections of chip sized coils with AgPd terminations with Pb free solder. The AgPd went into solution and there was essentially nothing left to solder to. We also had convex fillet shapes that clearly didn't meet wo

We'd be unhappy with features that are not in copper that is at the same level as the component pads, because of difficulties the fabricator would have in maintaining registration between the copper pads and the ink used for the features not in coppe

Every time to create new AOI program we must manual set at bright lighting level for each component. then this case we think the parameter of AOI setting it not concern for this problem due to the golden board that we use to confirm machine before st

DANGER WILL ROBINSON ! DANGER ! If your operators are not real careful the OEM support pins can get under the table frame and bend it. I have seen this happen more times than I would like to discuss. CP's must have the following: 1. Proper part hei
