How dangerous are the fumes from a reflow oven?

Flux fume is not for breathing, that is why every oven must have exhaust system. If you have some problem with health you need doctors help, don't waste time for answer which don't help you.

Stencil nano coating worn out

Electronics Forum | Fri Jan 10 10:37:34 EST 2020 | dontfeedphils

What sort of nano coating? The coatings that aren't snake oil tend to have a color to it. The other ones are typically wipe on and seem like a waste of time to me.

It's seeming more and more like I'll have to toss it in the trash, which is a bummer, but none of the typical e-waste guys want it since it contains no copper.

Yes those verifiers seem like a good idea but they really don't work correctly. You would be better off verifying with a meter during reel changes than wasting your life on that thing. I concur that single mount will show the value.

Totally agree with Evtimov. Let the SPI be the judge, as long as your getting good prints, your stencil is fine. I had a colleague cut the mesh on one side of a stencil and it still printed fine. This was proof to management that measuring tension w

Stencils with two PCB layouts

I worked at a place that routinely put up to six images on one stencil. Having two stencils for small boards seems so wasteful to me. Unless you are running them on two lines.

Thanks Wolfgang / Charles Have tried method suggested by Wolfgang on one product, and seem to be a bit over (perhaps density calculation was a bit out). Also, the volume of paste deposited must be less than the voume of the apetures on the stencil b

Absolutely Mike Lets take that one step further and say that almost anything that you use to clean up with will from then on be considered hazardous waste. Wiping rags/pads, the previously mentioned vacuum bags/filters, the piece of cardboard that yo

Thank you much folks! I've printed out these messages and will be acting on it with management. Interesting that I don't get hazardous waste manifests from the dross recycler but I do with my CLS chemicals for the washers (hummm....). I might ad
