Good day everyone, i'm struggeling to design a touch pad/button. i'm trying to design a touchpad with graphics integrated. the following happens everytime. if i'm using a pad in pcb designer, i dont get a soldermask on top. if i'm designing one with images, i'm not getting it to connect to my net/pin. is there a way to make a pad from image? if yes is there a way to put soldermask on top? of course not using solit, this will take to long for my design. my goal to achieve is: if i make a touch button. i don't want copper to be exposed(obvious reason statics). and i want to have a image inside of the pad where there is no copper nor solder mask. i did read a lot of forum post, watched tutorials. but i cant seem te find a solution. can someone give me a direction to look for? thank you

If you route a copper track into some part of the copper making up one side of the touchpad then that side of the touchpad will be connected to the track. The same thing is true with another track into the other side of the touch pad. This should not cause any DRC errors but, if you select either track going into the touchpad and press the H key, the side of the touch pad connecting to it will not light up because the image cannot be assigned a netname. Therefore any other track accidentally crossing it will not show up as a DRC error. This means you will have to be very careful with the design checking before you submit the PCB.
