Great!
1 of 1 found this helpful Works great. The heat transfer is very good. Something you can't achieve with a regular copper clad board. I am using this with 104 Cree XT-E LEDs which will then be mounted to a 20" long heat sink.
At first when I tested the aluminum copper clad board I thought it was a phony board with copper plated directly on the aluminum because I was getting a short circuit (no resistance) between the copper and aluminum. The edges are cut which connects both metals around the edges. Even when sanding all around the board it's almost impossible to prevent the both metals from touching because the plastic separation barrier in between is thin. But after etching (Make a circuit that has a etched outer edge all around) there was no contact anymore between copper and aluminum.
The aluminum back needs to be masked when etching or the aluminum will get eaten up faster than the copper. I made that mistake and the aluminum outer edges of the board got eaten up leaving the thin but hard plastic separation barrier showing. It was nice to actually see the plastic (or resin) separation barrier and see it's thickness. It's thin but not like saran wrap, it's actually very stiff and thick enough. It has good thermal properties that prevent it from melting. It also didn't melt or create a short between the copper and aluminum when I used a hot air gun to heat the bottom of the board in order to reflow the solder for the surface mount LED's.
