Aw Dave - you guys are so fashionable, are the dark green and red combos seasonal? caramel brown like a Pale Ale? I once heard that the green was chosen because it gives the best color contrast for white silk screens. As for color reflecting or abs

Basically, what is the main issue which requires you to use black fiducials? Stencil mark recognition issues? Solder printer machines have ability to adjust the brightness or contrast.

Hi Guys,recently i am facing an issue. Refer to the attached photo. This PCB is high RF speed, gold immersion single layer. After reflow, my solder seems to have black stains on it. I tried with SAC305 paste water soluble and no-clean, both results a

Am looking for a dispensable water soluble solder mask or peelable solder mask that can be dispensed and be run through a reflow oven with no swelling or degradation. Any leads on any materials or manufacturers to contact?
