DIP headers / plugs that actually fit into DIP sockets witho

I need to fabricate adaptors for PLC packages and discrete parts to
fit standard DIP sockets. Unfortunately, I have not yet been able to
find suitable headers to use as pins for these adaptors.

The headers I've thus been able to find are based on strips of molex
type pins, and the pins are much "fatter" than true DIP device pins.
This usually bends the connectors in the socket so far out of shape
that they can never again make solid contact with the pins of a real
IC.

Does anybody know if there are avaiable DIP headers whose pins are
closer in dimension to that of real IC pins? If not, can you suggest
a workaround using more common parts? (I've already tried using IC
sockets, but the pins are much thinner and weaker and don't securely
plug into place, not to mention that there's no place on top to solder
wires and components).

I recall seeing DIP plugs for ribbon cable with teeth and a pressure
fitting cap. These should be suitable, as they were made to plug into
a standard DIP socket. I could simply discard the cap and solder
directly to the teeth. Alas, I cannot seem to find them in any
catalogue. I don't even know what to properly call them.

Thanks for any advice!

I sell http://www.voti.nl/shop/p/DB-QPIN20.html, AFAIK these are quite
normal pin strips

If not, can you suggest
a workaround using more common parts? (I've already tried using IC

Use round-pin (machined) IC sokets instead of the cheap (single/dual
wipe) version.

Hi!

I make replacement PCBs for custom ICs on arcade game boards, like this one:

http://www.leopardcats.com/gatearray/gatearray.htm

and I use turned pin headers on that board:

http://www.leopardcats.com/gatearray/gaunder.jpg

They make an excellent contact to weak sockets, and don't ruin them, you
can easily put a DIP back in after that board has been in and out dozens
of times. The set of pins that plug into the socket are smaller than the
pins on the top side that solder to the other board.

The only down side to those is that they can be expensive, about 80p
(US$1.50) for a strip of 20 pins in the norm, unless you buy them in
large quantities.

Yours, Mark.

They are the best ( if expensive ...)

Commonly known as DIL IDC header plugs. Not so commonly used these
days but still available..

Several uk suppliers have them
