Step 8Preparing the Interface Connector
Our goal is to use the removed switch's contact pads to put in a 3x2 connector that will allow easy access to the module.
In the picture below you can see that all the holes are drilled and all the trace cuts have been made. If you look at the removed switch's pads you can see that 6 have been selected and the outer 4 of the six enlarged. This is because the switches pad to pad spacing is not the same as the connector. I used an #50 drill to enlarge these holes and you can see that I destroyed the pads. I should have used a smaller drill. If you can retain some portion of the pads, the soldering work is much easier.
