LMZ evaluation board: card edge connector?

Other Parts Discussed in Thread: LMZ14202HEVAL

I'm using two different LMZ142xx boards in a system prototype development and need to mount/secure the boards in enclosure. The eval boards (e.g. LMZ14202HEVAL) appear to have Vin, Vout, and ground on one side of the board (in large widths of copper) in what appears to be similar to a card edge.

Questions:

(1) Would use of a card edge connector be useful here? Or would contact resistance or other issues mitigate against this use? (Current could be shared over several 'pins'.)

(2) In the alternative, what are the dimensions of this board edge (tab)- the other option would to be use a card edge connector but only as mechanical support.

Trying to avoid other option- drilling holes in boards and using stand-offs. Thanks

We put edge connectors on our boards for ease of testing. Part of the testing is done in an oven and to connect to the edge connector on the EVM, we built a female edge break out board. I would think that the edge connector would be useful for you as well. How often do you think you will remove and connect the board? If the answer is 'not too often' then this is the way to go.

Thanks for info. I guessed that is why they had edge contacts.

I would only connect/disconnect infrequently so contact should be fine.

Any suggestion on particular card edge connector to use? The board is .062" thick, correct?

We use this: 307-020-500-202 from www.edac.net/product.html

You should be right about the board thickness.
