IC Pin-width Pin Headers

I often find myself making and buying boards to fit into IC
soctets. Usually these use pin headers, but the standard pin
width is too thick to fit into machined pin IC sockets, tends
to damage the other (cheap) IC sockets, and can be unreliable
in ZIF sockets.

Pin width doesn't seem to be a commonly varied specification of
pin headers. Does anyone know where I could buy pin header
strips with IC socket compatible pins?

Nothing? I've got some solderable plugs that fit in a DIP16 socket,
suitable for wiring resistors between pins. Can you still get them?

Picture coming.

Yes! Thanks. Not cheap, but now that I know what I'm looking for I
can shop around.

This looks to be the product I was after:

And with a little more hunting around that site, I found the pin

They're just the normal pin header stips that I said didn't work
at the start of the thread. Great for sockets designed to accept
pin headers, not for those designed to accept ICs.

The ones Aries Electronics make have smaller pins in a slightly
rectangular shape, like DIP IC pins. Unfortunately the type I'm
looking for seem to be tricky to get, and not cheap enough to
use as flippantly as I was envisaging (especially with postage
- come on Mouser, $24 to send a few pin headers to Aus?).

I believe that these might be what you're looking for:

Phil designed the pins for his OSHChip project, but everyone kept asking
him about the pins, so he made them a product too.

You're missing the point. I want to plug into sockets where I can
also plug in ICs.

In the case that inspired the post, I discovered that I had been
delivered the wrong chip (long story) for a project I was building
on a PCB. Because there was going to be a 1week+ wait to get the
right chip, I decided to substitute another chip with functionality
similar enough for testing. But of course the replacement chip had
a completely different pin-out, so I dug out the DIP plugs (which I
pictured earlier), thanked the stars that they were also DIP16, and
wired the substitute chip up to match the used pins of the original
chip.

So I sat back and thought "that worked great, but what if the chip
had a different pin count? If I had strips of IC socket compatible
pins, I could do that for any size of chip I wanted. I could even
replace the pin headers on all my chip adapters so that they work
better in IC sockets and my breadboards." But it was not the first
time I had thought such things, and I knew that my attempts to
find pin headers with narrower pins had failed completely in the
past, so I ended up starting this thread.

They look interesting, but I'm looking for something where the pins
are self-supporting like a pin header, so that wires can be connected
directly to them, as well as circuit boards.

It did lead me to this review though:
http://blog.tynemouthsoftware.co.uk/2017/02/flip-pins-review.html

Which noted that I might be looking for "pin strips", which it turns
out, unlike pin headers, do come in a small range of different pin
diameters (and spacings). More hunting and I found that the 350 series
made by this mob:
http://www.precidip.com/

They have small enough pins (0.4mm), and the right spacing. However I
havent put the time into finding a good supplier yet. RS have these
from the 850 series:
https://au.rs-online.com/web/p/pcb-pin-socket-strips/7020168/

They'd work if I cut off every second pin. The price is right, and
I getting pretty sick of searching for these (the bloody things all
look the same in the pictures), so unless I get more energy or
suggestions, I might just go with those.

I think that it is you that is missing the point, ICs plug into these
sockets just fine.

Using these gives a much more flexible solution than actual IC sockets,
you can use them to make any IC compatible layout or any layout that you
wish, instead of using IC headers you just use proto board with pin strips.

Nice picture, but I just tested this with a few chips and it doesn't
seem to work. Sure, the pins go in, but the fit is far too loose to
be reliable in the long term. Furthermore, checking with a multimeter,
I found that some pins would only make contact when I actively pressed
down on them while taking the measurement.

Trimming away the top of the sockets with side cutters may prevent
the latter problem, but the fit is still too loose, and the hole gets
messed up by the cutting, needing then to be fixed up with a small
screwdriver.

On top of that the additional height would have made them inappropriate
for the case I described because the PCB has board-mounted LEDs and the
chip would sit too high to mount the board in a case, even with the
correct chip inserted.

This type of socket strip strip is designed for ICs, and I've used them
a few times before:
https://www.jaycar.com.au/machined-pin-ic-socket-strips-32-way/p/PI6470

But of course standard pin headers don't fit in them. Dual wipe types
accept both, but after being attacked by a pin header, they don't grip
normal IC pins much better than your pin header sockets.

My earlier response doesn't seem to have materialised on my server but
the IC pins don't reach deep enough and are too narrow to make proper
contact as per that diagram.

time I had thought such things, and I knew that my attempts to
find pin headers with narrower pins had failed completely in the
past, so I ended up starting this thread.

I think that it is you that is missing the point, ICs plug into these
sockets just fine.

Using these gives a much more flexible solution than actual IC
sockets, you can use them to make any IC compatible layout or any
layout that you wish, instead of using IC headers you just use proto
board with pin strips.

My earlier response doesn't seem to have materialised on my server but
the IC pins don't reach deep enough and are too narrow to make proper
contact as per that diagram.


It works for me.

And with a little more hunting around that site, I found the pin

I use these to make plug in daughter boards.

They're just the normal pin header stips that I said didn't work
at the start of the thread. Great for sockets designed to accept
pin headers, not for those designed to accept ICs.

so you use these

http://www.altronics.com.au/p/p5390-oupiin-40-pin-header-socket/

cut to length, very useful to plug in ESP8266, ESP32, or Arduino nano
boards too.

You're missing the point. I want to plug into sockets where I can
also plug in ICs.

In the case that inspired the post, I discovered that I had been
delivered the wrong chip (long story) for a project I was building
on a PCB. Because there was going to be a 1week+ wait to get the
right chip, I decided to substitute another chip with functionality
similar enough for testing. But of course the replacement chip had
a completely different pin-out, so I dug out the DIP plugs (which I
pictured earlier), thanked the stars that they were also DIP16, and
wired the substitute chip up to match the used pins of the original
chip.

So I sat back and thought "that worked great, but what if the chip
had a different pin count? If I had strips of IC socket compatible
pins, I could do that for any size of chip I wanted. I could even
replace the pin headers on all my chip adapters so that they work
better in IC sockets and my breadboards." But it was not the first
time I had thought such things, and I knew that my attempts to
find pin headers with narrower pins had failed completely in the
past, so I ended up starting this thread.

I just tried it again with new strips and the iC's are loose. I can't
see how that could work reliably. How deep are yours?

I tried trimming down the end of one of mine, and even with the plastic
right at the end of the metal contacts the fit is still loose. There's
even a bit of wiggle room with one chip (the pin widths do seem to vary
slightly between ICs).

Even if there are some available with contacts close enough together
to work with ICs, I expect they'd get bent back the first time a pin
header was inserted, just like the dual-wipe type IC sockets do.

I often find myself making and buying boards to fit into IC
soctets. Usually these use pin headers, but the standard pin
width is too thick to fit into machined pin IC sockets, tends
to damage the other (cheap) IC sockets, and can be unreliable
in ZIF sockets.

Pin width doesn't seem to be a commonly varied specification of
pin headers. Does anyone know where I could buy pin header
strips with IC socket compatible pins?

get machined pin headers
