Alucorex face plates

Finally, I did a first test run. Exposure was done with 400 nm LEDs. Basically, once completed the exposure unit will look similar to this one:

So far I did just one of the three strip boards with 24 LEDs on it. I was too lazy
I ended up with a 20 min exposure at a distance of about 20 cm, though 10-15 min should be fine too.
All in all I'm pretty pleased with the result.
The white dots is some dust I didn't clean off before doing the picture.
Cool thing is that once etched you can wipe the surface with acetone or whatever you want. The black colour will never get off.
I'll probably give it a try to see how it looks with a thin clear coat.

Does Alucorex have a plastic core and is pretty thick?
Does it deform when you tighten down on it?

Nope, it's just plain aluminium anodized on both sides. It comes in 0.5 to 3 mm. Unfortunately, it's a bit hard to get if you don't want to buy a 500x1000 mm plate directly at Bungard. Reichelt in Germany sells a 480x490 mm 1 mm thick plate in black. This is what I'm gonna use.
Considering that you can make 7 plates from it 40 € isn't really expensive.
