- How to use UV curable Solder mask paint ?
Materials Needed:
1. UV Curable solder mask paint .
2. Thin plastic sheet.
3. UV light source -sun light or UV light.
4. PCB solder mask layer photoplots / printed on transparent sheet eg. OHP sheet. Dark area will be wash away. ie, exposed area become hard.
5. A piece of glass sheet.
6. Gasoline or nail polish remover for cleaning unexposed paint.
How to apply:
1. Make sure the pre-etched PCB is clean and dry.
2. Apply 2-3 drop of the paint on the PCB. We need to make a thin lair coating.So the paint quantity depends on your PCB size.
3. Cover the paint with thin transparent plastic film.
4. Spread the paint on the PCB with the transparent plastic film.Use squeezer to get rid of the bubble.
5. Place and align the artwork over the PCB.
6. Put a piece of glass sheet on top of it. This will help to press it together.
7. Expose under UV light or sunlight. This will take 1min to 30 min depends on your UV light source and thickness of paint.
8. Once exposed, peel off the thin plastic sheet and clean the PCB with Acetone or any other oil base solvent.
9. After cleaning expose it under UV light for a few minutes.
10.Now your board is ready for soldering.

I've just made my first PCB with a solder mask and this video was very helpfull! Thank you :)
Good job
Very cool, and easy-to-follow. And the music is great.
Sweet! Would love to try this
even though there isn't a voice over the music isn't bad its nice and soft.
spread the paint by putting a pane of glass over it and your mask will look 10x better.
Thank you so much for putting effort on this.
The PCB is really beautiful, I have to say perfect JOB bro...
It was so easy to learn this one.
Thank you for sharing this video.
This music rips! I love it
thanks for this tutorial, it worked well for me
Perfect! Thanks a lot! 😁👍🏼
Perfect homemade PCP. THX :D
Grieta tutorial, thanks for share! What step is first uv mask or drilling?
thanks,its really simple
nice ! gotta try it !
Your soldermask is beautiful and you should feel beautiful.
I like the background music :P
With yours it is very good result.....i have notice that you strangle to cover all the pcb area with such a little solder mask. I did that without success because i put too much on it. How you can tell is enough ?
Beautiful.
awesome!
Nice video.
Very good Thank you very much
What did you use to wipe down the uncured paint with?
Good work
beautiful
but you make the pcb with the dry film, you canot use the dry film for the solder resist also?
Is this uv curable stuff the same used for silk screen printing?
What do you use glue for bonding photomasks?
Can one use this for etching too?
Can I use permanent marker for the pads to cover it
Thanks.
Parabéns!
Nice video thank u..bro r u from India?
Keep it up
Thanks
thanks
any simpel way to do this?. we use spray fo this
boa tarde amigo imprimir papel transparente impressora tinta ou laser ??
Good video. Pls how can I print the photoplot.
Why not just use the etch photoresist and laminate it on?
Nice

I've successfully performed this technique about 25 times in the last year, but spreading the solder mask underneath the film is still really awkward, slow, and inconsistent. Do you have any tips to make the spreading easier?
By the way, thanks for uploading this. It's been a great help to the students at my university.
I will give the silk screen print cloth a try. A local second hand store here has stacks and stacks of silk screen printing screens still in their frames. You suggestion is a great idea!
What kind of transparent film do you use? Of all the times I've tried the paint dries to film and liquid paint stays on pcb pads.
i dilute the paste with alcohol and use a airbrush.. You get a much thinner coating which will allow you to see the traces much better (which is MY preference) and it will dry faster as well...
I'm using an UV light, how long should I expose the paint? I've heard people talking about 40 minutes but I think that might be too much.
many pcb manufactory use our xjh brand expose machine,just about 10 minutes.
Very cool music! Who's playing?
+Jonas Karud i liked the music too
Yeah me too... :D
I love it too! It's both relaxing and exciting and fun!
Really cool, it reminds me soundtracks of the old Amiga's games.
I need this song in my life, who plays it? I keep coming back to this video just for the song.
Same
salut
je cherche un méthode et comment fabrique le perchlorure de faire pour développer l'un circuit Electronique
the music is cool ohhh there was also a video,i did not noticed it :P
It looks like you go straight to exposing the mask after applying it. Do you need to let it dry before exposing?
Hi, the UV exposure is the reason that the mask actually dries, so you don't need to let it dry before exposing.
Some masks need pre-drying at 90°C, but the one he used does not need that
Nice tutorial, but that just seems like way too much hassle to go through for a single PCB after you're done etching. I think I'll stick with solderable lacquer.
ONE QUESTION PLSS !! IS NECESSARY TRANSPARENT SHEET FOR BLACK PADS ON TOP?? or I should use normal paper BOND? PLSSS .- Need help ! time ( 4:10 ) is necessary transparent????
it's used to block the sunlight or UV rays, so u might get away by putting a black colored paper to the pads.
This music.. woah.
how is the solder mask printed on the transparent sheet ? what sheet is that ?
You could use a sheet of transparency film, like the kind our teachers used before the internet was a thing (not sarcasm, just a statement of truth). They still sell those online and at Staples, Office Max, even at Walmart. I do not know if inkjets can be used for this technique as they use an ink, which may be compromised when exposed to the mask chemical (I honestly do not know), or if laser printers are used exclusively because toner is a thermoset plastic, which is very durable and depending on settings and quality of the toner, it is impermeable.
from where you got the the paint?
can i use any kind of paint?
Raj Wadia probably eBay, but don't use any kind of paint
You know you can get a nozzle for your syringe and use a little brush right?
Gotta admit that looks really good though
How would you remove the soldermask in the vias?
the vias are part of the "Mask" or "Stop" Layer in whatever EDA you are using, which is used to generate the image for the clear film (transparencies work great)
Hi, I have little troubles with this soldermask.
On big areas where there is no copper(exposed fr4) that soldermask peels of, why?
I use the laser printer method, use high gloss paper, then soak board in very warm water. the paper will fall away. then etch your board. work better than this method
+bill kabatoff Better even than your Mom \o/
+Nerin18 what is the purpose of your comment. What does my mother have to do with mother boards.
+Arek R. I had the same problem, you just need to expose it more. And try to peel it from the side that has more copper on
Thanks
Ive tried this way...but the paint got sticked to the transparent sheet...is b3cause the paint its not dry yet?
+Francirius did you find the answer to this issue? I've had similar problems, where it seems to prefer sticking to the plastic sheet rather than the copper.
+andy parry recently i change the type of transparent film and it worked better...i think its a thing of find the right one. Greetings
👍🏻👍🏻👍🏻👍🏻👍🏻👏👏👏👏👏👏
where I can get UV Curable Solder mask ?, thanks.
ebay

+Jared Elliott Thanks!!!
you can now buy soldermask film all you do is put it on top of your pcb and run through a standard laminator, and expose the positive image easier than using this method
dessie b but there arent't many shops wherr you can buy the resist.
No. There realy is a UV solder mask film:

I just came for the music.
WTF Through the fabric organza would have been better !!!
Credo... esperava mais.
Dont use glue to layer the two OH-papers. just use tape like wtf.
Adhesive solder mask film is FAR easier than this.
No es cosa, mejor encargar a las grandes empresas dedicadas, te sale mucho mas barato y no hay color nunca mejor dicho
Fake he showed ordered pcb. Home made3
Ok. That was excruciating to watch.
Small drops around the center - Really!!?
Why not a large(er) pool in the middle and work it outwards!!? That way you eliminate air pockets and is easier (As in takes less time, especially on-camera!) to work with.
Use some type of jig and/or fixture to hold the PCB while you're working it so your fingers doesn't depress the area you JUST worked over! This was done several times over.
thanks
