Nice job, I see most people just have cheap labor countries do it for them. I liked to do it myself, gives me one more skill and practical experience in making something. One great points in making it yourself is if has a fault, you find it fast. Where as you send it out, you don't see it till 2 weeks later!

[@yuppiehi]

LOL! A number of people are not fans of 8-bit music. Good video!

[@StefanNoack]

@dukat03: In the etching process, the photoresist gets destroyed by the UV light, and the exposed surface can be etched. However, the green solder mask gets hardened by UV light, the parts that were not exposed can therefore be dissolved. That's why they are opposite.

[@adracamas]

You people need to lay off. He's not mass producing or anything. Looks like a serious hobbyist. Nice work. Interesting music. Reminds me of '80s arcade games.

[@StefanNoack]

There are a lot of comments about the part where I check alignment of the layout regarding UV light. I am not looking directly into it. I put a white sheet of paper on top that converts the UV light into blue visible light. Also, the magnifying lens is only used because the camera I used did not have enough zoom. Nevertheless, these lamps are available to buy for decorative purposes, they do not produce UVB or UVC. I would not recommend staring into them for prolonged periods, though. Just use common sense and/or sunglasses.

[@pcbsolutionsdotcom]

Nice step by step directions. Looks like it would be fun for home projects.

[@104d_3rr0r_vince]

The music is awesome.

[@demnlordd666]

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

[@molorjul]

Excelent. Great job. I wish I have all your tools to create such a professional finish.

[@paulgalesko2761]

You are the king of the laminator.

[@miguelmartinez8665]

It is an excellent video very professional. Using some type of personal protection? Have you experienced any symptoms of dizziness, sore ears after using this material? I used it twice and I have experienced some of these symptoms for several days. Thank you.

[@daveburrows9876]

Is all that pricey equipment necessary? Could an iron fill in for the laminator? I remember hearing sunlight has UV light, too. Think I could borrow a little of that rather than the UV lamp?

[@stanvirg]

excellent video I bought some of this resist you exposed for 50 seconds with black light I have the MG Chemicals exposure kit which they recommend 5-8 minutes exposure for the'er presensitized boards how long should I expose solder mask for thanks

[@MegaKbyrne]

How far away from the bulbs is your glass in developement stage? I am building a wood box with four bulbs, regular bulbs but I may buy four black light bulbs if they are better.

[@mphRagnarok]

buddy you're looking at UV light straight, and somewhat magnified with a lens... you're gonna get cataracts in no time

[@anatoliynikolov8771]

I think as I did many times PCBs, that using this method it is not possible to mark as showed almost ready board the solder points and perforation for non smd elements (7th minute and 22 second)

[@zoltant.4915]

Oh yes, it is possible! Just use some kind of marking on the PCB (crosshair, +, X) anything you can use to align the board and the transparency. I'm using this technique since I quit using the pencil to draw PCBs.

[@Racius19]

Hello, I try to make some PCB using this dry film mask, but I simply do not understand, how can I laminate it without getting air trapped under the mask ?

[@pat60606]

...you can get small amounts on ebay...10ml to 100ml amounts in small tubes!! I got it before, works quite good!! Just search for Solder Mask!

[@jordanzish]

Is that a Maxtor HDD? Don't know why but I recognized the layout of the board from my old fried hard drive lol

[@SparkyLen]

Dumb question - is the film tolerant of natural lighting, or do you have to do the work in darkroom/safelight conditions?

[@user-zm5hk4cr3g]

Really nice. I have tried photoresist after toner transfer an it is awesome! I use negative film photoresist

[@HeartOfGermany]

Is it possible, to get a single PCB (2 Layers) for under 20€ or 25$ with about 7*4 inches? I don't need solder resist on it, also. No silk screening needed. Only a Double sided PCB. Is that somehow possible for cheap prices? Most manufactures start at 100€ because of the set-up costs.

[@dukat03]

You used the same toner method for the solder mask but this time covered where you want cut out, so how does the part you masked get dissolved ?

[@bibekchitrakar]

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 ??

[@MESSTOO]

WOW, REALLY PROFESSIONAL. A PERFECT PCB.

[@MottyRuttner]

right on! Adobe Master Collection CS5.5 Keygen..what type of electronics are you into?

[@kanishka5prasad]

whats the software that ur using to print the pcb to the transparent ! ? and im so confused about printing only the pads ! ? please explain me how you print only the pads !

[@somud1]

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.

[@despedes]

Hi, great video! Could you name some of these PCB fabs that you are using now? Thanks a lot.

[@bastiannonq197]

sodium carbonate So2Ca3 what is the mixture?

[@skeezixcodejedi]

I liked the music; good choices ;) The text parts of the video (top right) came through all garbled for me (flash player under linux, several years after video was put up to youtube) so guessing here; but what occurred during the soft brush application in the solder resist layer? ie: only the right pads came through withotu resist.. how is that? how did the actual traces not come through without solder resist? were you careful to only brush on the pad areas or something? (that can't make sense.) How accurate is home etching? I've only done it for very wide traces and low pin count.. never a surface mount part. ie: Can QFP64 or QFP100 be home etched, or far too fine and risky for that? With SMT theres not so much drilling needed, so it could be okay.. but I just doubt its possible to pull off without error? (I have a little drill press, and doing 200 or more drill points for the .1" through hole is really really annoying.. time to make a CNC drill/mill :)

[@StefanNoack]

Hi, the solder resist is exposed using a different set of masks than the traces. The solder resist uses a photopositive process: the parts that are hit by UV light get hardened. The mask covers only the pads so the resist can be dissolved there using sodium carbonate because it was not hardened by UV light. Be sure to give the hardening process some time to complete (c. 30 minutes) after exposing. However, professional PCB prototyping prices have dropped a lot since I made this video. I can even source prototypes from here in Germany that cost only twice as much as the materials required for a manual process, not including the time. And these are double sided, which is a real pain (yet possible) to do yourself. The Chinese are even cheaper (they manufacture PCBs down at about the same price as raw copper clad from my local electronics store!), but shipping time sucks, also supporting the local economy is a good idea I think.

[@skeezixcodejedi]

I've used elecrow a little; the regualr special of .. 10pcbs, 10x10cm max, for $13USD seems pretty insanely inexpensive; mind you, if you're in a rush and all excited, adding $20 for DHS delivery is nice.. otherwise you'll be waiting 5 weeks. Still, worst case.. $35 for 10 is $3.50/pcb and 10cm square copper clad in my area is a cople of bucks each, so thats hard to compete with; if you wait the full 3-6 weeks delivery, their prices are cheaper than the copper clad! I definately agree it is nice to keep $$ in the local economy, but we have our limits. As I'm relatively new to the electronics industry (I'm a veteran software developer, only been doing electroncis about a year now) I've been stocking up on gear from around the world; osciliscope for 40% the price of local; edge connectors and resistors/caps/etc, just 10% of the local price (and sometimes of dubious quality), and so on.. for gtting started, you just have to pick up a lot of stuff from Thailand, Honk Kong, etc, and then you can perhaps start to be choosey :/ At least general hardware (dremel/rotary tool, glue guns, multimeters, power supplies etc, ) are usually available locally for relatively good prices, everywhere.

[@damithsenarath1]

yer it s very good and how can i by that paper other one

[@MrDomyboy]

does anyone know of a supplier for black solder mask?

[@dizzuking]

very professional my friend

[@SuzanneKowalski]

that part from 7:16 to 7:26 - i don't really understand what makes the shiny metal soldering spots to appear and why aren't all the circuit lines shiny... could somebody explain?

[@SuzanneKowalski]

oh nevermind, the answer is at 6:14. :D

[@ntwede]

Elmer I was wondering the same thing. It didn't say anything about using a mask to mark those spots.

[@AirForce194]

C:/Users/ntwede.exe I wondered that too until I went back to check it

[@l1t7l3ph0o7]

after you expose to uv light the unexposed spots are removed through chemical process in the developing solution. which in turn exposes the soldering points. the circuit lines may not all be skinny, because of the electrical needs of the trace, it's part of his particular board

[@TheMrTape]

How many gigabytes should the harddrive used for covering the PCB have for this to work properly?

[@krishnasgowda9214]

I hav solder mask ink how to apply on board any idea?

[@kanishka5prasad]

should the pcbs have to positive photo coated !! i tried this method but no luck ! i cant get the print transferred !! and i have a home made 24 W UV lamp !! and my developer is Naoh !! i did as in the tutorial but no luck ! any suggestions please thank you

[@Penfold8]

Very professional looking! Great job!

[@ssssszszsssss]

nice work, however, these film masks are expensive. I wish there is an easy and cheap solution out there. I have tried using a cheap UV solder mask paint which i bought from ebay for like $3, but it didn't workout. spreading such thick paint evenly on the pcb is not an easy task.

[@princeaeromodelos]

Hello please can indicate where can I buy this dry film for solder mask, thank you.

[@unrealillusion87]

Sieht sehr gut aus! Wo beziehst du das Lötstop Resist?

[@Fuamaster101]

Great music.. Can you give me a title?

[@ColzaMania]

Can I use the solutions multiple time ?

[@dario76xx]

I get the same result, but the tin does not stick to the pads and the mask comes away with the heat of the soldering iron. waste of money

[@turkuas23626]

what is the power of uv lamps? and can i use photoresistive film to make pcb board not solder mask?

[@ivan868]

Transparencies for printing your layout - which brand of the paper, you amateur dude???? And which printer - laser, ink???

[@kanishka5prasad]

whats this lamp called ?

[@DarkAvatar1313]

How many hours (including waiting times) does it take you to complete a pcb from the beginning?

[@QSQCaito]

Really good! Would you mind telling me where do you buy the solder mask?

[@victorius2006]

2:52 You dont need to expose the board to UV light again... Only clean it with acetone and wash it with water then ;-)

[@shadowphobe]

The documentation from Dow Corning says post-develop cure with UV light, then thermal. If you read the official documentation for this Dynamask there are many recommended steps that most videos on KZbin are skipping. (like moisture bake-out before applying film). All of them contribute to stronger adhesion.

[@rajitharavindra4457]

woow .. fantastik. how to make with duble side printed bord ( phone circuit bord ) you know .. with i,m tell me. thanks

[@filisoft]

Excellent, I really like how you're working :)

[@igrewold2383]

What is that machine?

[@skilit007]

Very helpful info here. Thanks for sharing this video with us.

[@ixamraxi]

Very nice video, quite helpful.

[@sanity599]

It took you all day and a couple of hundred dollars in chems and equpiment. Is it worth it? Yes you did make a very good looking couple of boards but wouldn't it be cheaper to just send it out? I am looking at making my own boards and it doesn't look atht cost effective.

[@angelcs1jma]

8 bit music?, nice video!

[@Genesixs]

Muchas gracias por el video. Muy bueno. Saludos.

[@serafincastilla]

wow! 20€ for a 7*4" PCB?... this is crazy. In Colombia a double layer PCB of that size will cost 12 or 15USD including solder resist. No one in Colombia will pay 100€ for a PCB NEVER. Unfortunately the express cost to Germany or USA will cost you more than you save

[@stizandelasage]

i like this method

[@dukat03]

What do i need to dip it in NaHO for ?

[@pat60606]

...jees, how much work is that??? You could just use the paint on stuff, that screen printed on, then exposed to UV light...like all the places in china use to make boards!! Those dry film masks are so expensive and time consuming and im sure the amount of work involved would do your head in!!

[@MrPeacefullman]

Which etchant do you use? Thanks

[@StefanNoack]

In this video, it was Sodium Persulfate, but HCl + H2O2 works much better.

[@SamGib]

NICE

[@MottyRuttner]

keygen?

[@TheAlstani]

Nice work!

[@MegaKbyrne]

After your brd is finished can it be put into a solution of liquid tin? Is liquid tin necessary with solder mask? Kevin

[@StefanNoack]

Liquid tin works very well. I'd put it on before applying solder mask, though. It helps if you plan on storing the board for some time before soldering. The liquid tin solution itself does not stay usable for very long once it has been mixed, so it only makes sense if you are making more than a few boards at once.

[@MegaKbyrne]

Thank you for the help. Nice video also.

[@rou162]

you have a vga connector on that pcb :)

[@didaloca]

I hope I wont sound like an armchair keyboard warrior here, but isn't looking into UV lamps pretty bad for your eyes? Cataracts etc...

[@vadimzhikharev1243]

And what for a film?

[@mau2002]

where do i find "dynamask"

[@daskasspatzle2396]

Nice work, nice music :-)

[@klexn]

Love the 8bit music..LOL

[@truhlikfredy]

like your choice of music :)

[@BurkenProductions]

It's all great, but you shouldn't have the UV light on while looking down on it. It's harmful for the eyes

[@jazsm5385]

Thanks for uploading

[@DanFrederiksen]

kinky. but I just order finished boards from some of the cheap producers. sure it takes a couple of weeks but is just nicer and cheaper

[@EngrAbdulWahabKhan]

GREAT GREAT VIDEO

[@DiyguitarpedalsAu]

I feel like i should be watching the c64 load screen :)

[@Supervisor000]

8-bit music rulez!!!

[@vambreace]

good work!. cool music!!!.

Very nice :)

[@Dantakurai]

FINALLY There's a Video Were it Shows a DIFFERENT Circuit Board Color then Yellow, God Those Yellow Tutorials PISSED ME OFF ! I've Been Trying to Find a Black and Blue (Black is Dark Blue)Tutorial Everywhere But Can't Find it,I'ed be Glad to Subscribe to you IF you show me How to Make a Black and Blue Tutorial... PLEASE... Just in Case you Don't Know What I'am Talking About, The one at 0:13 looks the Best!

[@DigitalWorldBG]

Thank you for video!

[@mckma382]

Great work, though you are are much more patient man than me.

sehr cool, gutes Video!

[@nicoverduin4745]

Of gewoon spiritus :)

[@RCTutz]

can't you just put it outside in the sun? I don't have a UV light :$

[@sebibv15]

Nice:)

[@jonhdoe1395]

+1 just for the chiptune

[@milek021]

Like final look, "professional", but as I see your pcb is not so "precise", traces and smd pads don't have that "sharp", clean edges as they should have with UV exposure method ( best seen at 07:58) ?!

[@rethnagireeshwar7199]

excellent :)

[@djbanki23]

I though in the Core team or razor 1911 hahaha.

[@yenaurapourtoulmonde]

Please focus your cam!!! It's all fuzzy... :((

[@StefanNoack]

I know, sorry. That camera could not get the close-up shots into focus, that's why I'm using the lens to show the details. I got a much better camera now.
