Place a label and etch that instead of the PCB. Too many variances in solder mask

What type of material is your solder mask?

Scalpel, audio book or a podcast. if you have a micro bead blaster that would be faster

First, splitting hairs on parlance. * Conformal Coating. A thin electrically nonconductive protective coating that conforms to the configuration of the covered assembly to provide environmental and mechanical protection. * Solder Mask. Coating mate

Hello Mike You'll have to be a bit more specific. Do you mean permanent solder mask like the normally green material or a temporary mask like the peelable/washable material? John Thorup

We now put soldermask on copper and then immersion nickel/gold plate our fine line boards. One of our vendors says this causes skipped plating in small via holes and wants to nickel/gold plate the whole board, including via holes, and then apply sold

One thing that will also cause this is very slight stencil mis-alignment. Sometimes the paste will have a tendency to hang up in the apertures if you are over hanging just a little on the solder mask. Some solder mask are very slick and will not pull

Hi, Thanks for the ideas. With the solder mask curing problems, can you normally wipe off the white residue, as we can do this on our boards with our fingers. It's almost like the surface of the board has a "wet dried up" look to it, and it's a smok

Russ, I tried to get a screen for glue but the design engineer who laid this board out made up his own rules. The 0402 pads are to close for a proper dot size.....per the stencil house. That is why I am going the solder mask route. I would rather
