I've been soldering on a molex 70 pin .5mm pitch connectors to pcbs with the trusty fry pan.
I've got the application of the paste down to a fine art now and dont get many bridges.
Still, I need to check that all is OK before I load the rest of the board, picaxe, V reg, R's caps etc. I have been going around with the MM but its slow going.
I've heard of bed of nail test jigs. I am familiar with gold plated spring probes that I could use as the contact points.
The way I see it Id draw up a pcb that would have probes mounted on it that would correspond with the 28X1 DIP pads , R pads etc when the board to be tested would be lowered onto the bed of nails.
The board to be tested has 2.4mm holes in it for mounting bolts. I figure I could have some rod machined to this size and mount it on the test jig so the board to be tested would slide down the rod on two points so it would correctly align with the jig underneath it.
Then if there were bridges in the molex connector Id have an arrangement where LEDs would light that would indicate which pins on the connector were shorted together.
Am I on the right track?
