Looking for a specific connector

[James Morrison]

Hello all,

I have a 1x6 0.1"-pitch connector that I use to program a Microchip PIC.
I am now going to production so I'd like to not populate the actual
connector. Does anyone know of a connector that would mate into this
footprint and then somehow be engaged to expand to make a good
connection. Then it could be easily disengaged to contract and allow
extraction after programming is done.

I could use a standard 0.1"-pitch male connector but this doesn't make a
great connection and you have to hold the connector against the side to
make a good connection--and some times that doesn't work well.

It seems like a good idea but I have no idea what to search for. I
tried a bit but came up with nothing.

Thank you very much. Merry Christmas.

James.

google "bed of nails"
eg

hope that wraps well
you have a jig with spring loaded connectors that connect to pcb
holes.

Although I haven't seen full clamps manufactured for this kind of thing,
pogo pins such as those found at www.idinet.com can give you spring-loaded
contacts that break through oxidation and center beautifully in holes
originally designed for 25 mil square post (for instance).

Vendors such as AQL Manufacturing Co. (9755 SW Commerce Circle Wilsonville,
OR 97070 - local to our company) can supply pins and pin assemblies. They
make many of the test fixtures for our test engineers, I understand.

Martin,

Thanks for the idea. That is a possibility. Given I'll need a test jig
of some sort this could work.

In my mind, I was looking for something to go onto the end of a cable
(like a connector).

Cheers,

James.

Martin,

In my mind, I was looking for something to go onto the end of a cable
(like a connector).

Some years ago, there were "low insertion force" and "zero-insertion force"
connectors, that they'd use in stuff like EPROM programmers. There also
used to be a thing called a "DIP plug" that got crimped onto the end of
a piece of ribbon cable, which you'd then plug into an IC socket.

I probably wouldn't want to populate a board with a ZIF socket if it was
only for one-time use. If you can't afford the time to plug in an ordinary
IDC plug, then a bed-of-nails is probably your best bet. You could take a
look at AMP MODU, if they still make such things.

Good Luck!

something that should work for you.

I use a simple 8-pin IC test clip for PIC ICSP. Epoxy and hard-wire a 1x6
header to the clip. One additional bonus is not having to route the
programming lines. It works fine provided you have clearance for the clip.
