remove varnish mask on a part of a track

sdecorme over 6 years ago

Hi,

I would like to know if there is a solution to remove the varnish mask on a part of a track on circuit studio ?

I have not enough place to make the track at the right size so I need to solder a wire on the track.

Thanks

I've followed this tuto How do I create a custom pad shape? I copy the bottom layer and I change it to bottom solder . It seems to works.

Would you not be better adding a surface mount pad rather than just removing the solder mask?

Yes, you did it the correct way. Draw your shape such as a rectangle or copy the shape from another layer on the solder mask layer (top or bottom) to open up a window on the solder mask. Be sure not to draw on the paste mask layer or it would result in putting solder paste when they assemble.

To be proper, you should make the solder mask window opening slightly larger (0.05mm to 0.1mm) than the copper you are exposing to allow for alignment of the solder mask application. In your case, it may not matter much if they are the same size.
