connecting non-permanant wires to a PCB

Hey all!
Is there a best way to connect wires non-permanently to a PCB? I have my circuit on one but I might want to remove the 14 LCD wires which I haven't connected yet. Any way besides terminal blocks (too large) and pin headers(hard to find from here, besides I can't drive yet)?

    I use header pins on the board. I keep a supply of single and dual in line pins. I cut them to needed length. I've found surplus computer cables that have dual in-line connectors from 10 pins, on up. These cables can often be utilized by only plugging in part of the pins, for example, plugging a 40 pin cable into a 16 pin header.

    These components- the header pins and connectors can be orderd by mail. Allelectronics.com might have what you need. You might be able to scavage them from old computers.

    any sort of Cannon-type connector....or, if you have the space, go with an old db25 parallel port connector.· IT's got enough pins but is kinda bulky!

    Hello,

    ·· Our Parallel LCD Display uses a ribbon cable, connected to a dual-row socket.· This mates to a 14-pin Dual-Row Header on the board.· Easy, and often used in the industry.· You can see an example at the following web page.

    Since, you said you can't find pin-headers where you are, it is kinda hard to come up with anything.

    Dual-row Header sockets are a bit dicey when they are inserted onto a DIY board. And, they require those pin headers or a plug.
    The 0.1" spacing with two rows is very tight for soldering wires to move about the board.

    There are three things you can do.

    1. Use some kind of single in-line format that allows you to make your own cable.

    2. Get a DIP to ribbon cable for the board. You can either solder it into the board as intended or use it as a plug into a DIP.
    I guess you want the plug-in option. It won't hold as tightly as a Dual-row Header, but it will be a lot easier to solder in and around the board.

    3. Start salvaging from old Personal Computers. There are lots of ribbon cables and various sockets in them and their cards. If you can find a cable and it's plug- take both.

    DIP?
    You mean a chip socket??

    i recently discovered these two items at digikey
    3M1020-ND female socket
    H1816-ND header

    they are a 20 pin (2X10) header/socket pair that i use in my designs. the pins are 2mm by 2mm apart which makes the components small. the female socket fits nicely onto the edge of a pcb if you want to vertically mount pcb cards onto a motherboard pcb.

    in any case you could push small gauge (20awg methinks) solid conductor into the holes of the socket and they fit snug.
