We have been wave soldering mini-melfs for many years. Main problem for us has been excess and bridging joints but few skips. To overcome our problem we provide a minimum of 0.5mm clearance around each component, not great use of real-estate but prov

It depends how you value things. I know lots of companies just look at equipment costs, but if you include development time, you may find it very expensive: and it may not work anyway. Generally you can by a tru AOI Sanning system for about �35K and

The new format doesn't bother me. It seems less cluttered. The adverts do seem huge, but the old forum always had that white space on the right side. Maybe we gave up that white space to get bigger ads. It does seem faster. I wish they had retai

We use AOI in-line on most our SMT lines, and still getting them for the rest our lines. It has cut down on Inspection Time considerablly, justifing the cost. They do take a trained technician to program and that is a little time consuming, but worth

We have had a problem with some resistors on some conformally-coated boards which, after a few months in the field, started going bad -- a real worst-case situation. The resistors would increase in value dramatically and sometimes develop diode-like

Wow! Nope, wouldn't wanna see it and hope I never do. Our 7.4 RS quake (that lasted for 45 seconds!) August of 1999 in Istanbul happened at 3AM and the plant was closed. We ran production that day starting at 7:30AM. Only 2 people failed to show up

We've got some products at the sample run stage that we are using hand soldering to assemble and the results are terrible, especially in the reliability of the product. I found this one company that has a machine that places the part AND laser solde

Thank you Dr. Abell for yr response. I am not sure if I have understood yr Point # 3 clearly. Are you suggesting that CBT run on Corporate Intranet (where Bandwidth, Accessibility etc.is under control) is the real answer in the current situation ? If

Only used adhesives once and it was a disaster. I don�t rearly have much experience but the real problem is everyone wants to compare adhesive with solder and they will not give the same results. There is a good book on adhesive check out my book re

Yes if we are going to be lead free than lead will have to go. There are alternative plating finishes, Shipley have been doing a lot of work in this area. Also have a look at the NPL web site. Some people say that new crieria is necessary but I thin
