hey if you want a cheaper source of uv, a small 75wat (i believe) mercury vapor lamp has more than enough uv to work for several boards at the same time, aslo they last quite a while. last time I checked small UV bulbs in the fluorescent tube style they were 12$ or more each. so with the 5 or 6 you have there thats a lot of $. buyt one Mercury lamp ~$20 maby less, I know for certain they come in 125W for about that price. less space less fragile long lasting cheaper. try it
@demnlordd666 I got those tubes for cheap (the price has now even dropped to $4 each!), but for larger PCBs I would probably use a mercury lamp. Thanks for the tip.
Great video. Certainly answered some of my questions. Looks like a lot of work, but I guess it's all worth it when the result is a nice, professional looking board that you can start populating with components. Cheers!
Your UV tubes are incredibly weak though... are those disco lights? Interesting that this actually works. You can even put a CCD-Sensor into the open light, doing so with my cam would not just blind me to pain but the sensor as well.
@linuxgeek81 What's blinding you is the visible part of the mercury emissivity spectrum. These lights are indeed actually decorative lights with a layer that indeed absorbs most the visible spectrum (which we don't need here anyways). However, this makes the tubes get warm quickly, which is quite helpful, especially in the winter. On camera they seem even weaker because there is a rather thick piece of glass in front of the sensor that absorbs UV light.
One of the best pcb-making tutorials I've seen on Youtube! Liked especially the Dynamask solder resist part, since it's quite rare on home made pcb's and therefore can't find good tutorials how to use it.
I am going to try out this product from Octamex as a result of this video. If it works out you have my greatest gratitude. I sure wish my results look as good as yours.
I see that Photo resist was already present on the copper board, I've never seen something like that before. what is it called? Fantastic video by the way.
@somud1 well, it's pcb base material with photoresist already applied. in the store where I buy it, it's on the shelf next to the bare copper boards. There is a blue protective film (painted black on the inside) on it to protect the photoresist. you need to remove that before using them.
@DarkAvatar1313 I guess - without all the videoing, handling the camera and lighting and doing parts again because I messed them up - it would be like 2 to 3 hours, not including making the layout of course, though including the one hour wait time for etching. However, I got all the stuff (especially safety gear and a fume hood) for etching with hydrochloric acid and hydrogen peroxide, which is what I'll try next to reduce etching time to a few minutes without the need for external heating.
@DelxSus check the video description for a link to the site where I bought the solder mask sheets. The sheets are called "Dynamask" and the shop where I bought them is called "octamex" and is located in germany.
I used what it said on the label. That's 10g/l for the NaOH and 200g/l for the Na2S2O8. The proprtion for the Na2CO3 doesn't seem to be critical but I try to get something about 10g/l there, too.
you have a vga connector on that pcb :)

Where can I get the dry film solder mask.
Didn't found any vendor Dynamask... ?
Would you please post a link where can I by the solder mask film ??

@Noah1989 In this video no actual technical UV-tubes are used, they are not harmful but not suitable for this kind of application either.
