Re: F.cu connections to pins soldered on B.Cu
|
Greetings, As enciclopedic information (I was never do it before), I know that the process involve the activation of the PCB and then the copper deposition by electrolysis. regarding your question I found this instructable that I neither do it yet too.

One of the proprietary breakouts is the Arduino Pro Mini - the brains of the operation - which has a footprint like this
Assume I have a two-layer PCB:? most of the pins of the Pro Mini are connected to traces on B.Cu but some must connect to traces on F.Cu.? As illustrated, this footprint is just a collection of standard pads.? How do they connect through the fibreglass of the board?
I guess this is a silly question to those of you in the know, but it has me stumped.? I cannot find anything on the Net or in any literature which explains this mystery.? I hope one or more of you can help.
Thanks
