Looking for a specific connector

Dec 13, 2005 9 Replies

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

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.

or get a Molex catalog from your disti rw

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! Rich

. Take a look at

to see 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.
