How can I handle missing solder mask opening on PCB footprint?

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?

You can use a burnishing pen, scratch brush, or fiberglass pen. It looks like an eraser pen but has fiberglass brush bristles come out. It’s much more precise, gentle, and safe than a knife, dremel, or sandpaper. Just pretend it’s an eraser. Normally used to scrape away oxidiation and rust.

Is there a surface-mount component I can put on a pad, that simply has another pad on top that I can solder something on to?

We found that edge-mounting a TO-Can package to a PCB will really save a lot on manufacturing. Echter, it comes with fairly long through-hole pins that are taking up too much space to reach the pads. Any suggestion?

How to handle feedline of bluetooth PCB connected to a 2.4GHz chip antenna?

I’m making a 4 layer PCB prototype that uses a bluetooth mcu connected to a 2.4GHz chip antenna. I’m thinking about what to do with the feedline, whether it should be buried on one of the middle layers, or left on the top layer. To get a 50 ohm line, should I choose top layer with 13-mil width or buried miccrostrip with 7-mild width?
