PCB mounting holes #139

Closed charlespax closed 9 years ago

The PCB standoffs on the enclosure now have a shoulder to secure the PCB more firmly (https://github.com/PaxInstruments/t400-enclosure/issues/64). This requires enlarging the PCB mounting holes. The keepout area on the PCB is the same, so this should not require any change to the layout or routing.

@starno What are the new dimensions of the PCB mounting hole?

starno commented 9 years ago

4.5mm diameter in the same location

Current mounting holes are 5.08mm diameter. Is that OK?

That screenshot shows a 2.54 mm hole. I don't understand.

Sorry, I made misunderstand on the value. here is the corrected drill size image

Looks good. When we manufacture the PCB we'll have to make sure the holes are not plated, which would reduce their diameter. Closing issue.
