pcb edge clips

Autosplice or NAS/Interplex used to sell them on bandoliers.

Looks like Autosplice ran into patent issues - but they have a solder ball smd offering.

I don't know who sells them, but similar pins are used with LCD displays. You might check with some of those companies. Pacific, AND, Varitronix...

I've seen something like that used on LCD glass.

I might've seen EMI shield clips like that. Give Laird a look. Natch, you won't have high pin density or anything... this would be more for power.

That looks like useful stuff, but all the surface mount clips are half a mil minimum order quantity.

why not just use the pads? sorta like a QFN package

or castellated vias if you want to make it a bit easier to hand solder

SMT LED packages (TMB, for Transfer Molded Board) are small PCBs sliced right through the PTHes. Of course the thermal gradients during cool-down would cause residual stress with a larger daughterboard, and something easier to clean under would be nice.

castellated vias seems quite common for RF modules and some BGAs are basically a chip on a PCB

We've done that before, like in this adapter:

but for obscure reasons I'd like to lift the baby board up a bit.

these look interesting

Thanks for the links.

Digi International is trying to cash in on your idea.

"Digi SMTplus form factor (patent pending)"

If they are trying to patent the sliced pads, they can't, because we sold our boards about a decade ago. And we didn't even invent the idea.

I have about half a reel of TMB-packaged 1206 LEDs from about 1999, so it' even older than that.

Would castellated half-vias (vias that are half-cut-off at the edge of the board) work for you?

As I mentioned a few posts up, we have done that. But in this case I really want to lift the baby board a bit above the main board.
