Last weekend another CPFer came over to the shop and we made some fixtures/jigs to hold Luxeon emmiters to the top circuit board of a sandwich module. The fixture will hold the emmiter in the center of the board, and apply pressure to make sure it is in good thermal contact with the top board.

You can find the picture of it (fixture-01.jpg) here.

You can see the two pieces to the left and right, and one put together with a sandwich module in place. The whole thing is heavy enough to stay put when you solder the emmiter's leads to the board.

Very nice! /ubbthreads/images/graemlins/thumbsup.gif Would be great if you could make a jig for the O-sink/Hotlips C/D too. /ubbthreads/images/graemlins/rolleye11.gif

I had thought of that too. Prehaps next time.

This is a great idea. I was thinking...

Would this work with a non-threaded fixture as well? The top sleeve could slide down over the post and the weight of it would supply enough force to hold the emitter down until the epoxy set up. This could simplify the manufacturing process by eliminating the threading.

It looks like the top fixture fits around the plastic sides of the emitter. It may not fit the Luxeon K2 coming out (this summer??).

This is just some food for thought. This is a great idea and I'm sure it could save many hours of frustration due to non-centered emitters. Cheers,

Paul

Awesome tool from the sagacious mind!! From the pictures, high temp from soldering will be dissipated at the LED. Interested in buying one if you will make extra.

Yes it could. Dat2zip has already sugjested doing it that way. I have re-drawn the plans, so IF I make any more, that's how they will be.
