One thing that you do not want to do is run a 240V oven at 220V. One place I worked a few lifetimes ago had an oven that had five top zones and only two on the ends on the bottom. It was something like 440V but supplied with 408V. It took a long long

The problem you create by soldering from solder destination side (presuming you have already soldered from other side) is that you will trap air in PTH so you have virtually no continuous solder in PTH from one side to other. This will not meet IPC-A

I agree that Moonman is a pretentious wannabe in the industry. His site has no relevant information, the only humur in there is a picture of his fat finger pushing a button. Myself and my collegues here thought of making a "fake" consulting company

That link doesn't work for me. From the more you explain - it does sound like an issue I've had in the past on a few different builds. In the end we traced it to a fault with the paste (they were having mixing issues in the chemistry) but they as y

Hello Michel...this might be a bit of a battle finding the low thermal EMF material that you are looking for. The first one that comes to my mind is Bismuth Selenium Telluride, with either a nickel or cobalt doping agent. Silver went away from this

Well, another alternative is to use a water washable flux. If you insist on staying with a NC flux, use one that is probable. We prefer to probe solder, rather than copper.

We've only seen it done by accident, and the result was a lot of white flux residue. You do need to make sure you get it all off, and to do so most likely means using a saponifier like sara suggested.

YIKES! Using a micowave to warm a tube of paste has "evil" written all over it.
