Module board discontinuities?
Use a sharp crafting knife to gently scratch off the etch resist (the green stuff) then tin the traces with a little solder.

If there is a break that is too wide to bridge with just solder use a single strand of wire as a jumper. (Offcut resistor leads work great)

If you want to replace the resist after, a little clear nail polish works.

Test the continuity after with a multi-meter.

If they are high-frequency signals, it may affect performance though.
