pcba cleaning

It depends on the flux type. If it's water soluble, it should be cleaned soon after reflow because OA flux remains active after reflow. If it's rosin or no-clean (low-residue), then the only concern is the longer wait time, the more difficult it will

Appreciate the input from everyone. The PCB is .062" thick. As a CM we are at the mercy of our customer at this point although (hopefully) they are receptive to advice on the next build. Titanium strips could be an option, I also thought there might

As has already been mentioned, black residue is usually either from dross or just a dirty pot, pump, baffles, etc.. I also saw that maaaany years ago in a system that used a flawed oil intermix "feature" but hopefully those systems are long gone.

Paste drying on stencil

Electronics Forum | Fri Feb 07 20:41:52 EST 2020 | orbitcoms

I am finding if I have to stop the pick and place machine during production very often (mostly due to feeders not pulling the tape cover back), I get paste drying in the apertures of the stencil. To avoid this I am thinking of pasting all the boards

Why gold plating on PCB?

Electronics Forum | Fri Feb 28 01:36:43 EST 2020 | crystal12

&gt; What is the use of gold plated boards? <BR> <BR> With the increasing integration of IC, the more IC the more dense. The vertical tin spray process is difficult to flatten the pads, which brings difficulty to the SMT mounting, and
