Ken,

Two quick solutions come to mind.  You must remember these are "quick and dirty" solutions for the inventory on hand.  To really make these two boards perform best will require some modifications to the bare boards.

Simple solution 1 - If there is available space drill holes to accept a tie-wrap.

Simple solution 2 - If there is no space to drill, what about self adhesive "wall mounts" on each board and then a tie-wrap connecting them together.

A less simple solution would be to use some of the board-to-board supports like Richco DLCBS-6-01 or Richco SP-6-1.  This will require holes in both boards.

Just one man's opinion.

Phil

Subject: [TN] How to secure daughter card...with not lock-in type
connector


Technetters,
I have a problem: A small daughter card (2" x 3") is mounted on a mother
board. Daughter card has a mating connector (without locking mechanism)
along the one of long edge. Other edge of the daughter card is fastened
using stand-off and screws to mother board.

As this connector is not a lock-in type, any twist to the board can make
connector popping out so slightly that it fails during the test.
Fastening at one end is not enough and the vendor does  not make
connector with lock-in mechanism. Hence, looking for ideas as how to
secure the daughter card without going through respinning of the fabs.
May be one of you might have faced the similar problem. The gap between
daughter card and mother board is about 0.375".

re,
Ken Patel
