Another possibility for eliminating need for donor SLT cards when making substitute cards

SMT SPRING CONTACTS MIGHT ALLOW ME TO MAKE PCBS WITH INTEGRAL SOCKETS

I found some gold plated spring contacts that are .098" wide and solder onto a PCB pad. They can be set side by side to form the 12 connections on each side of an SLT connector. Their height above the PCB will create a .257" width between the two sides of the card. Since the SLT backplane (board) pins are spaced at .25", this should give a decent fit with adequate quality connection. 

I ordered some and will experiment to see how they work with real SLT boards. This is easier than having wires running from PCB pads to a standalone connector which must be anchored somehow to the PCB (see earlier post).
