Subject: [Homebrew_PCBs] Drilling PCBs

From: Robert Hedan <robert.hedan@...>

Alan,

I can't do those tricks 'cause I design my boards so that they can be
outsourced in the future. I want to design my board as it will be done in
'production', so if there are design anomalies I should detect them during
my DIY prototyping.

If I use unorthodox techniques of wrapping wires around the edge of PCBs and
such, that will not mimic 'exactly' how the production board will react.
I've switched to SMDs, I find them better, but they are not for everyone.
Those with bad eyes, shaky hands or serious sneezing problems won't be able
to use them.

I'm also considering through-hole plating. There are times when having my
'future magic CNC machine' punch eyelets into a PCB would make my life so
much easier. I think I would be happy with a manual system of placing the
eyelets and having the CNC pressure-stamp it into place. I am not doing
mass production, as long as the CNC can 'step through' the via positions and
let me press a STAMP button after I've placed an eyelet, I'd be extremely
happy.

Robert
