Well the profiler IS out for calibration so I can't use it. However, what piqued my curiosity is your statement concerning uneven heating. On the product we were running we had several non-liquidous solderjoints where as the rest of the joints looke

Hi, we use Vitronics Delta 6622 solder wave.I try to adjust high of backplate, but I don't know whether the adjustment is correctly.Now, when the frame enter in the main wave, solder flow in the same direction as PCB.But when the frame go above main

Creating a sound tin nickel intermetalic takes a bit more energy than other finishes (such as copper or tin). You can achieve wetting, but not have a viable intermetalic. You should cross section some intact boards from that process and see what th

Reading the original post.. Floyd, do you remember the old overhead projectors back before we had the new fancy video projectors? Just get a clear sheet of that plastic and print your outline on that. Put that sheet over the stencil and presto, you

A PCBA contains a couple of parts that are not sealed and can't be water washed. We hand solder these with no-clean after everything else is water washed. The designer says the no-clean residue must be completely removed so that it will not affect

AJ, You can use 0402 feeders to place the 0201 parts. I would suggest getting the feeders you are going to use calibrated before trying to run the parts. Also, another good idea is to get some 0.4mm tape leaf covers for the feeders. They will h

I have been searching for a compatible high temp chain oil other than Tribol 1421/SG due to cost cutting, which is what electrovert is recommending. I was wondering if anybody can tell me beside Tribol 1421/SG. What other brand out there that is come

The german machines use the same basic procedure as the Compact Systems CS-400E but (to my knowledge) no cut and clinch. Can you give any information about manual visual inspection after stuffing boards with such machine. If stuffing boards without

I agree that wave soldering is probably your best method. Of course if you can, tin the wires in a solder pot before insertion into the board. The solder that would be there will probably facilitate wetting a bit better. If you absolutely have to

The flux dries out and the paste sticks in the stencil apertures. As the flux dries it also causes the solder to oxidize. Hahaha ! I remember adding flux to paste back in the day to loosen it up. Do not do it ! I have been told by reputable industry
