Plated vs non-plated

What exactly is the difference between PTH's and non-PTH's? PTH seems
to be standard spec in pcb manufacturing.

You couldn't Google that basic question?

One hole is plated, the other isn't. Obviously.

Of course PTH is the standard spec, because that is what most people want
and need.
There are also reasons you want some holes to be specified as non-PTH, but
that's another question.

It is less standard with punched boards.

Punched boards? Which boards are punched - very high volume consumer
appliance on phenolic?

Yes, and also some relatively high volume commercial and consumer
boards using epoxy-glass.

An historical note: There was a period, in the late '60s, if memory
serves, that the military was banning the use of plated through holes
(holes with plating to make electrical contact between pads on more
than one layer). The reason was that the PTH technology was not
advanced enough to provide reliable connections. During that period,
manufacturers had to place wires or electrical components through the
holes, and make solder connections on both sides. This was viable, of
course, only for 2 layer boards. Today, of course, the military
allows PTHs.

And inserting those pins that used to connect one side to another was real
b**ch. I've done loads of single sided stuff though. Audio often doesn't need
any more unlesss you're miniaturising.

You bet, although one quote we once had using CEM material actually used CNC
drilling simply because that's what they were set up to use. They actually came
in cheaper than punched phenolic. This is thousands though, not tens or hundreds
of thousands.

I didn't know anything other than paper-phenolic took to being punched. I
imagine the tool would wear out a lot faster.

probably still less wear than drilling that number of holes.

You'd have to do an economic analysis. Never seen any punched FR4 though. It
would be quicker of course, that could be an incentive.
