Nice, but couldn't you just have bought some?

Nothing that was just right. The hole sizes were wrong for these pins, or there was no room for a label. These will boot ARM processors an/or FPGAs. They'll plug into sockets so customers can field upgrade code. You can't get these flash chips as DIP parts any more.

We ordered one breakaway panel of these, about 380 little boards. Our purchasing lady always writes "solder sample required" on PCB po's, so they did it... a whole second sheet for free.

That is nice, and useful too.

If none fit then you had to. You could buy die and have a packager put them into DIP but that only makes sense when its tens of thousands.

Had a similar experience. Ordered 50 or so proto boards for a client and they already panelized for later, for production. I think we got two sheets of 40 each, with 30 on the 2nd sheet crossed out with a thick Sharpie. I bet that'll come off with denatured alcohol :-)

I think I beat you to it. No funny skewed traces, either ;-)

(bad photo- shiny baggies) Good for SOT23, 89, 223, DPAK, SO- up to 16, and a few TQFP44's just in case.

They are elegantly contoured, I'll have you know.

These guys have some cool adapters

but their SO8 to DIP one didn't quite work for me this time.

I was toying with the same idea, and for the same reason. DIP8's seem to be going extinct. And SOIC8 and MSOP8's seem to be interchangeably out of stock.

Well, try not to dislocate your shoulder patting yourself on the back!

I was doing that crap 30 years ago - actually, 30 years ago, you could walk into an electronics geek shop, and pick one up off the shelf!

But, hey! Congratulations for not being senile yet! ;-D

Well, I once did a six-up by hand. Double-sided! ;-)

Well, I didn't do the board layout. Only the schematic.

John

You mean you didn't use the autorouting?

Big money to be made at $2.95 a pop. Look, they're out of stock! You can move in on their territory!

No component Values?
