Using a ZIF socket for testing Chips in DIL board sockets

The cheap textool and 3M clone sockets that you can get from China have rectangular pins and are impossible to fit into a turned pin socket. But if you apply a bit of force, they will push into a stamped pin socket. And then the stamped pin socket should fit in a turned pin socket.

I used 0.1" SIL turned pin male-male headers & soldered these directly to the cheap ZIF socket pins.

Push the headers into a turned pin DIP socket as a solder jig and solder header pin-zif pin from the side. You can then fit the whole lot into any socket on any project easily. I am away from home at the moment so can't post a photo of one... they aren't pretty but very functional. They get tall too but work fine while you're repgramming a PLD or regularly replacing and EPROM.

I prefer the turned pin SIL headers to the turned pins on DIP sockets because they are a smaller diameter so don't damage the springs on (crusty) old DIP sockets...
