Dumb question time: PCB vias

[Jim]

There are small spacer like tubes that can be placed through the vias
linking both sides.

What are these items called?

I'd call them circuit board pins. But most of the ones sold these days seem
to be solid rather than hollow (tubes).

You mean " placed through _holes_ " to create a pseudo double-sided pcb.
I think that idea went out about 30+ yrs ago. You can always solder the
component leads on both sides to get the same antique effect though.

p.s. a true *via* does actually conduct from one side to the other.

OTOH did you want a 'terminal relief' type things to attach wires to PCBs
?

Maybe he means a ferrule ?

I've seen them called eyelets. Germans call them "Durchkontaktier-Nieten" or
"Rohrnieten". Something like "tubestaples". The smallest ones I saw so far
are 0.8mm.

I've seen them used a long time ago to make a double-sided board without through
plating ( but a real genuine 'via' IS through plated anyway ).

Their other use is to form a strain relief for attaching wires to a pcb.

I bought a Multicore product years ago: it was a heavily tin plated
length of solder about 1mm O.D. ( with other diameters available)and
was scored around the length every few mm so you could snap of a bit,
insert it into a hole and using the special tools ream it into the hole
and then desolder it to leave a tin lined through hole.

The tools were too expensive to but so I used a pair of long nose
pliers with the ends heated and bent 90 degrees so the tips touched
together after grinding smooth. This let me squash the tin/solder piece
in the hole so it expanded and locked in tight before desoldering it.

I bought it from Farnell over ten years ago and I don't know if
it's still made these days.

Or a 'via' ? !!

Thanks for the responses.
