Hello I am new to creating PCB’s, and I was wondering about how Fritzing handles PTH holes. I want all my holes to connect both layers, so they need to be PTH holes.
Do the gerber files automatically generate the PTH holes? I’m sure how to correctly decipher the drill.txt file. How can I make sure that all the holes are plated?
Thanks!
The production board houses all do through hole plated by default as far as I know. You may be able to specify non-plated through but the default is plated through. The drill.txt file specifies which holes are plated through (all in this example) like this:
; NON-PLATED HOLES START AT T1
; THROUGH (PLATED) HOLES START AT T100
M48

because both sets of holes are t10x (as opposed to Tx), the 2nd line applies and the holes are plated through. Two holes are 0.038in and the other 2 are 0.048in.
