To draw a plated through slot: - Use the trace tool on the board layer to draw the contour of your slot:
- Put multilayer pads at each end of the slot:
- Use the polygon tool to draw copper bands on the top and bottom layers so the slot gets completely surrounded with copper on the both top and bottom sides of your board:
- Use the polygon tool to draw rectangels on the top and bottom unMask layers so the slot is clear of solder mask to allow soldering:
