pick-and-place thru-hole parts?...

[John Larkin]

I\'m imagining a board with about 100 small relays. The relays would
have ordinary pins poking out the bottom of the can.

We could hand place them and then use our selective solder machine. I
wonder if a good pick-and-place machine can load thru-hole parts onto
a board.

And I wonder if a PCB could have tapered, funnel-shaped plated holes
on top, to guide the pins down. I once did a board with countersunk
plated holes.

If there\'s a spot for the sucker to lift the relay I don\'t see why not.

If the pick and place can do a 0.4mm BGA there no reason it can\'t put
0.6mm pins in 1mm holes.

If there\'s an issue with the feed tray having the relays crooked, you
might need to use the camera or nudge them a bit before picking them up.

Usually they drill a stack of panels in one operation, with dummy sheets
of some sort of melamine faced mdf or something on top and on the bottom
of the stack. If the holes are tapered, they will have to do one panel
at a time. That will cost more. As would special tapered drills that
they would need.

Two types of through-hole pick & place machine visible in this art film
from circa 1980:

Did they send them all to China?

(I believe the cars under construction in the second half of the clip
are final round of 2nd generation Chevy Camaro)

If the holes are countersunk and the relays are large enough you could
prolly program a small industrial robot to do it, just keep it fed with
a tray of relays like ice cubes.

This one is 15k which is maybe competitive with used general-purpose
through-hole pick n place machines, but there are probably cheaper options:

Lot smaller than a pick-n-place machine, too

We have a new Yamaha p+p, super precise. Just thought I\'d ask for
opinions.

as long as the holes aren\'t super tight and the pins aren\'t too long and floppy, I don\' see why not
through hole used to be automated too

can\'t get the relay in SMD?

The available, multi-sourced ones are the 10x20 mm 1formC with pins.

I actually want about 25 formB and 75 formA, but 1formc would do for
all the 100 relays on the board.

This will be a cable tester, a box one can insert in a cable to
simulate opens and shorts and snoop signals.
