Yeah, many people use those for this application and I even have some,
both DIP and SIP, but the thickness of the pins on the ones I've been
able to find is more than an IC leg and they don't fit well into
machined pin sockets; are yours thin enough?
I feel they are. And, they fit into machine pin sockets.
I've used them in commercial products for 15 years, and no complaints,
even after folks reverted back to non machine pin ICs.
I don't think one has to be exactly as thin as an IC pin (they make IC
pins just thick enough to handle the force of pushing into a socket, no
more :-), but rather no larger than the expected width a leaf socket
expects.
And I don't use the component carriers as is; I extract the pins while
watching a baseball game or some other mindless distraction and then
insert them from the top through the pcb, trimming off the forks after
soldering. Admittedly, I wouldn't want to do 100 pcbs in one sitting
that way...
Yeah, I can see that as viable for very small batches, but I get ROM
adapters and such assembled in batches of 100 or 200 at a time. The
cost to handle it that way would be prohibitive to the hobbyist nature.
I do agree the regular square pins available at most electronics
connector houses are too wide, they spread the leaf socket out too
much. As has been noted, the cheaper Arduino male-female headers you
can buy on eBay work great as well. They are about .1mm thicker than
the IC pin thickness.
