How to make a PCB prototyping with UV soldermask - STEP by STEP

[@lhxperimental]

The quality is impressive.

[@WEGSTRCNC]

thank you very much :)

[@billgianzin710]

fuck this shit the best video on pcb making .....

[@ehsandaneshvar]

yea

[@ufohunter3688]

Absolutely the best I've ever seen. Wow.

[@indrjeetmaurya6039]

helloworld

[@loosrudi]

Excellent from start to finish. You showed more information, technique and quality in 6 minutes than I have been able to see in 6 hours elsewhere. The video quality was superior to many others too. Thank you.

[@ELECTRONOOBS]

So awesome! I'm impresed with the quality!

[@TheFandiahmad]

Wassuappp guys wllcome back 😂

[@devers6]

Did I just see what I think I saw? First, cutting the traces with absolutely no burr raised in the copper; a notorious material to machine. Then, milling the solder mask so precisely that the copper underneath appears unblemished. This is pure magic! I’m going to have to get me some of those cutters. Magnificent video!

[@developandplay]

That pcb locks at least as good as if it was produced by a professional pcb manufacturer. Maybe even better...

[@annamunoz2331]

Hi I would like to know if this works for heal welding paste? www.amazon.com/gp/aw/d/B018C71QHI/ref=mp_s_a_1_1?ie=UTF8&qid=1496107658&sr=8-1&keywords=QUANS+110V+20W+UV+Ultra+Violet+High+Power+LED&dpPl=1&dpID=51Gx6Lp91VL&ref=plSrch

[@thechriskelly12]

This would work to cure the UV solder mask as it outputs UV light if you are unable to leave it outside to cure.

[@santhoshsamuel1055]

Joop Brokking Hey it's great to see you here. I think you'll build this thing in your next project, as you selects the best project

[@jakparter9163]

hi i watched many video of making pcb but i have to say this is the best video i have seen wow i love it sooooooo much thank you

[@Rainbow_Oracle]

So in a nutshell, Step 1: Design the PCB Step 2: Mill out the traces (from a blank, copper-laminated board) Step 3: Apply solder mask (to protect the exposed traces) Step 4: mill the solder mask off the contact pads (to allow you to solder components onto their traces) step 5: Drill any necessary holes and cut out the PCB Step 6: Protect the now-exposed copper contact pads from corrosion with tinning solution PCB DONE

[@abiralr.baniyachhetri4418]

Was looking for a comment that summarizes the process... Cheers!!!

[@toufictafech2833]

what about via holes in double sided PCB

[@EdwinFairchild]

you can buy rivets on ebay and stick them in the via holes to make the connection from one side to the other that is what i have done in the past with homemade double sided boards

[@cheaterman49]

I was wondering if the tinning step took care of that, I suppose not.

[@ExarchNZ]

The tinning "sticks" to the exposed copper, so there is not any copper inside the holes only around them, so the tinning does not stay in the holes.

[@marcelobgil8204]

Muito além de uma simples placa, uma obra de arte. Meus parabéns ao cara que fez tudo isso 👏

[@БурятИванов]

То же самое я делал в 70-х годах прошлого столетия.Только вручную и резаком. )) Прогресс...

[@ellpigy]

Просто вся суть в том что ты делал, а этот чел только сверла менял )))

[@jeffcole5708]

One of the best boards I've seen, stunning work.

[@lukasadamek3980]

Thanks for the comment!

[@FernandoGoias81]

Best video of homemade PCB that I ever seen. Excellent result! The UV solder mask solution was what I was looking for. Now it's time to buy this CNC engraver. It's not expensive.

[@Andrey-rl5yj]

мой мозг от таких видео улетает в нирвану you super

[@leezhieng]

The best quality pcb milling I've seen thus far.

[@Elementronic]

Amazing!!! The creator is very compent. Congrats

[@tohcp5729]

Perfect home make with high standard method....unbelievable

[@neut1121]

i can't believe how perfect this turned out

[@dallasnyc2887]

Absolutely beautiful. The milling of the solder mask is awesome.

[@mortaldrumming]

great video. what brand of soldermask did you use?

[@MaxintRD]

Very nice video that gives a great view on how a very professional PCB can be made in small quantities and short turnaround time. Thanks!

[@ajk1278]

Tak tohle mně dostalo. Coby strojař a obdivovatel cnc, smekám. Dokonalé, nádherné, perfektní PORNO. LÍBÍ !!!

[@therestorationofdrwho1865]

I could watch this thing make boards all day.

[@jeffthom3155]

The quality of your board is amazing! Very good indeed, congratulations!

[@grassoft]

Very professional, congratulations. Thumb up.

[@ThuanDuong-pv3xu]

To WEGSTR CNC : perfect and professional : I desire to have it. !

[@MrEksol]

На это можно смотреть бесконечно. Шикарная точность и качество.

[@M6MDR]

How does the machine maintain an even depth of cut on PCB? Thx.

[@blrcnc9848]

There are other softwares for that like Autoleveller, PCB Probe and OpenCNCPilot.

[@molomono9795]

I think this machine milled it's own bedding which ensures the gantry and bedding are aligned very well. As long as you lock your pcbs down correctly it should allow you to skip auto levelling. However if you dont' want to mill a bed (which is pretty easy). For a software solution: You can autolevel in the Gcode itself (wiki.linuxcnc.org/cgi-bin/wiki.pl?PCB_Milling_And_Drilling_With_Cheap_And_Simple_Height-Probing) It looks a little odd to use but basically, the steps consist of downloading the github files and running a python script. The generated G-code does height probing before cutting, it gives perfect results every time.

[@gibo588]

[@waelmokhtar3176]

What about the double sided & Via ?

[@publiusenigma8065]

Have you come up with a solution for metal plating the through-hole/vias/drills so that top and bottom layers are connected?

[@johnw1385]

depends on what country you are in. afaik the good ways cant be done at home in usa due to drug war chemical bans

[@electronicshelpcare]

Amazing man.... using domestic items and making PCB...

[@alejandroperez5368]

Yes, everyone has a CNC milling machine under their beds

[@PrOxDES]

Отличная технология pcb. Спасибо

[@markusfuller]

Hello Lukas, I have this Wegstr machine but my old pc with parallel port died so the cnc machine is not in use now and just sits redundant on a shelf. I hear you are working on a USB version, when that is completed would it be possible to buy the USB control board only and place it into my parallel port Wegstr machine to get it runnig again but on USB?.

[@WEGSTRCNC]

Hello, more information via email....

[@markusfuller]

WEGSTR CNC Thanks I have emailed to your website :-)

[@Markitos203]

just wired the thing with an arduino and GRBL.. cheap cheap cheap

[@med6402]

that is the beautiful thing i have ever saw in pcb creation

[@LetiferTV]

now I just need a job to be able to buy that CNC machine x'D

[@freakyou123]

1. What are the dimensions of the PCB? 2. How long did it takes from start to finish it all? 3. What about the vias? Did the tin solution connect the top with bottom layer?

[@fevermusicstudio9941]

How did you generate the tool paths for the solder mask? I am using FlatCam but dont know how to invert the pads so the tool will clear them.... ?

[@lukasadamek3980]

Steps just according to the video - we used Sprint-Layout for design and Cut2D for tool paths (it is done from picture generated during designing).

[@fevermusicstudio9941]

Thanks. I just found out that Sprint-Layout has an inverted option on the gerber output which does exactly what you did in Cut2d. I ran it through FlatCam v8.5 and it works nicely!

[@thechriskelly12]

What type of cam operation did u use to engrave and remove the mask e.g pocket for holes?

[@jeromequintard7375]

Jan, how you are sure, you do not damage the very thin copper layer instead just milling the solder mask ? What is the solder mask height, is this constant ?

[@lukasadamek3980]

As you can see on the video we used the spring bit. It is just simple spring placed under the V-bit. This ensures the constant depth of the milling if there is some bump.

[@WEGSTRCNC]

You have to clamp the spindle on the right place - just below the overhang

[@instein8042]

How you prevent to damage the copper tracks when removing the solder mask with the cone tool? Presure control?

[@WEGSTRCNC]

we used the spring bit for that control

[@pargyropoulos]

Milling the solder mask seems strange to me. How did you calculated its exact thickness and how did you ensured that you milled away just the right amount of solder mask? I your milling depth was was a bit wrong you would either mill the copper pads or you would leave a thin film of solder mask that would cause problems when soldering. Please clarify.

[@StephenGachara]

Sprng tension milling technique ensures only light force enough to mill the mask and little or no damage on copper.

[@WellPCB]

great!I watched the video several times. This process made me very happy.

[@shinningraj]

I'm truly enthral by your video. i always like unique things, innovative things. thank u so much for uploading such professional quality stuff.

[@robr3015]

How do you not go through the copper when you mill the solder mask? The spring?

[@WEGSTRCNC]

yes, the spring is the key

[@tiberiumdsv2321]

I never considered using a spinning tool to remove soldermask. I've been using transparencies and acetone.Your approach is remarkably superior. My cnc machine doesn't use a set-screw for its tools, it uses a collect chuck. Do you think the spiral engraver and spring combination will still work?

[@WEGSTRCNC]

It is not so standard combination to use the spring below the bit. But it works.

[@lhxperimental]

How did you plate the holes? Also how does tinning work? Also I noticed a gold finish. So how is that made possible?

[@lukasadamek3980]

Holes done by drilling. Tinning work done with tinning liquid (10 minutes in that). There is no gold.

[@VladaNish]

How do you calibrate Z coordinate after you put the milling tool and how deep to mill PCB? I don't see any z-axis sensor. Also, how come that after milling the solder mask pads comes out white? Does your software also calibration for double sided PCB and how would that work?

[@WEGSTRCNC]

There is no sensor for z-axis. You just have to setup zero points for every axis and manage the deep of the milling in designing software. The depth depends on the material. The white/silver color is made by tinning. Our software is not calibrated for double sided PCB, you have to be handy :)

[@ChipLogicRO]

im really curious about the type of foil used when puttin on the soldermask (transparent one)

[@WEGSTRCNC]

just common plastic material + glass

[@petrlicht]

Tak to je hustěkrutopřísný :-)))) parádní prácička...

[@WEGSTRCNC]

Diky :)

[@CheloA]

Quedó muy prolija. Felicitaciones!

[@packratswhatif.3990]

Just beautiful ! I would imagine that the setup cost of the equipment is high to start off. Maybe not really meant for the hobbyist. But we can dream .....

[@incandescentefilms5861]

with that cnc you could do smd and smt pcbs? , what is the precision of that cnc in mm ?

[@lukasadamek3980]

we didn't try SMD or SMT PCBS. The precision is 0,04 mm.

[@incandescentefilms5861]

amazing, do you have the gcode of that video, i would like to test my cnc

[@lhxperimental]

Have you tried doing pads for 0.5mm pitch QFNs?

[@lukasadamek3980]

No, we didn't try that.

[@citizenjags1309]

what synphony was used in this video?? I love it.

[@mrakjunior]

Damn good! I can't even tell the difference the factory made and this one.

[@ufohunter3688]

What are the bits made of (Carbide, Diamond, HSS, etc), and how often do you have to change them since you are cutting into fiberglass?

[@WEGSTRCNC]

It depends on many factors - speed, material, milling in liquid,...and the material is carbide.

[@ufohunter3688]

Thanks for the amazing video.

[@Vladimir_Radio-Master]

Вот это уже ближе к делу. Паяльная маска это хорошо ))

[@mikrotik1z]

Excellent Tell me please, how is the mechanism of the spring-loaded of the mill? I want to make myself the same

[@WEGSTRCNC]

See our next video kzbin.info/www/bejne/raOanWltqMlmhK8

[@mikrotik1z]

I saw this video, but there it is not clear how the spring holder of the mill is arranged, which stands in the spindle I have a Chinese spindle, for the ER16 collet and I can hardly imagine the device of such holder I believe that there are a lot of nuances there, such as feed, spindle speed, angle of sharpening of the engraver, after all it is necessary to cut only the layer of the solder mask and not to touch the copper I would be grateful if you could tell everything in detail

[@chriswouse7713]

Does the milling software know that you are continuing your job and ask for a fiducial reference, when you are milling the solder mask?

[@WEGSTRCNC]

you have to setup the default point manually

[@andredefariassilva3459]

amei o projeto . onde consigo cnc dessa ???

[@themanthis837]

Very good quality video, thumbs up.

[@georgedukic9955]

that spring tool doesn't take the copper off?

[@WEGSTRCNC]

Just the solder mask

[@Nandox7]

Amazing quality... When it is milling the PCB where does the dust goes?

[@WEGSTRCNC]

The dust is cleaned by air

[@retronexusnet]

How did you know how deep to mill, after applying the solder mask to remove the mask on the pads so just the copper is visible at this point then?

[@WEGSTRCNC]

that is why we used the spring bit

[@retronexusnet]

hmmm... not sure if I completley get it because you need to have some measure of drilling depth in place, dont you?

[@WEGSTRCNC]

The depth of the drilling is about your design and generated tool paths of the workpiece. For that purpose we use e.g. Cut2D from Vectric company

[@retronexusnet]

That far I agree, but when you apply the soldermask how did you manage to get just deep enough so the copper pads are not damaged?

[@WEGSTRCNC]

As I wrote in the first comment. For that purpose we used the spring tool which manages the right depth of the track. You have to setup the right pressure controled by the length and strong of the spring.

[@just.observer4648]

yeah it looks ok, but gow long dose ir take to produce, is it realy cost effective?

[@WEGSTRCNC]

it is a good way to do the prototypes...complete procedure takes about 1 hour

[@TheSh_dow]

I have the same question, is it cheaper than using one of the German PCB prototyping websites ?

[@samubiker]

Hi, nice video! What is tinning? Witch sostance is? Thanks!

[@WEGSTRCNC]

Hello, it is tinning liquid and it is good to protect the PCB before oxydation.

[@71GA]

Which solder mask was used in this case? It is really nice and shiny.

[@WEGSTRCNC]

Just common solder mask bought on ebay.

[@71GA]

Thank you. Did you get it in a tube or was it a foil?

[@CoolKoon]

+Žiga Lausegger You can see that in the video. It was in a black plastic jar.

[@sebastiangodzina]

Look awesome! Now I want one of this CNC machines ;_;

[@sharavanigraphics.4588]

Which chemical are used for tinning

[@jcbarrales]

how did you get that transparent finishing?

[@WEGSTRCNC]

Tinning

[@xaviermarin4485]

Great job ... what kind of liquid do you use for the UV mask?

[@WEGSTRCNC]

it is just some common liquid bought on ebay

[@tubelins]

What is the transparent film that you use at 3:08 to spread the ink for the soldermask? I tried some but all of them took parts of the ink when I removed them...

[@cw752]

wow, ver good job! How does the engraving bit with the spring work?

[@gere364]

What are you using for tinning the pcb?? Do the vias been plated??

[@WEGSTRCNC]

gere364 It is common tinning liquid. The vias are not there but video with vias is in preparation..

[@fevermusicstudio9941]

Two things: the board appears to be a thicker than usual type of PCB... and second: Why did you use a spring for the solder mask clearing?

[@lukasadamek3980]

The board is not thicker (it is FR4 based material). We used spring bit to mill just the exact part of the material and it also balances the bumps.

[@WEGSTRCNC]

PCB is 1.6 mm thick

[@fevermusicstudio9941]

Thanks for the info!

[@casaicasa]

I could use any software pcb Design for genered geber file ? Or i must use a specific software, for cnc work ?

[@WEGSTRCNC]

You can use whatever software which can generate g-code

[@norbertobarajas6181]

Hi, I'd like to know what drills you used and where I can buy them. Regards.

[@WEGSTRCNC]

Hello, you can get these drills on our website www.wegstr.com. The diameter of the drill depends on your needs.

[@ferdinandobrito4376]

Can you tell us for reference how long the isolation milling process took?

[@WEGSTRCNC]

about 1 hour

[@pharoahking4275]

to save time, cant you mask first and then mill out the traces?

[@Rishi45001]

You could but your traces won't be properly masked. If you mask first and then mill, the sides of the copper traces will be exposed allowing for solder to make accidental electrical contact. Also your PCB will have a really rough finish to it...possibly even leading to accidental peel of the solder mask/copper trace. Sort of like scraping a stamp of a letter

[@pharoahking4275]

@@Rishi45001 brooo. I realised that the next day. I must have been high

[@TreaHuggs]

I am also curious as to doublesided vias. Also can you just pop in gbr files from eagle?

[@WEGSTRCNC]

Hello, the double sided PCB with all the components is in preparation. Follow our channel to get the newest videos.

[@Wingstechcorner]

Great method. I was looking for a engraver/drag method of removing resist without using UV/overlay to avoid needing to get a laser printer. Nice. Now I just need to find a 30° bit that is setup for springs for ER11 setups...

[@CarlosHernandez-sl3zv]

which CNC mark or model you used? what type of liquid you used?

[@WEGSTRCNC]

all the projec is done on WEGSTR CNC machine, see www.wegstr.com and the luquid is for specific for tinning

[@polimorph2023]

The real thing looks better than the simulated one. Nice job!

[@cheaterman49]

This is impressive, it looks like it freshly came out of my manufacturer! I didn't realize CNC's were precise enough for you to remove the solder mask without drilling through the 30µm (or so for 1oz IIRC) of copper. I'm also wondering what you used for the tinning, will that properly make your through-hole pads connect from front to back?

[@WEGSTRCNC]

As it is not double-layer PCB the back side is not connected.

[@criznach]

Very clean cuts. Which engraving bit are you using? Looks like a spiral V bit. What feed rate?

[@WEGSTRCNC]

Yes, we used the spiral bit and the V-bit....all you can see on our website wegstr.com/index.php?route=product/category&path=61. Feed rate is 170 mm/min.

[@BunkerSquirrel]

Just wanted to remind you that KZbin has a no porn policy. Outstanding video work. And what a awesome cnc machine!

[@Psychlist1972]

I really like this. But I assume the one thing you don't have a process for her (besides printing/screen) is plating the through-holes, right? I assume the through-hole components here wouldn't work without you then soldering both sides, and that vias wouldn't work at all? Tinning would just cover the copper.

[@jnevercast]

You can electroplate the vias but you'll need to drill the holes first and plate, and then mill the traces and mask.

[@glegoo6912]

[@ellpancha]

very good job, but my pc, does not have that port, only usb, will it work? how about the software?

[@lukasadamek3980]

I would recommend you to buy old PC with parallel port. Regarding the software you will need something for designin your workpiece (e.g. Cut2D, Cut3D, Aspire) and software for machine controlling (Mach3). For PCB prototyping it is Sprint-Layout.

[@thechriskelly12]

would you do a tutorial on how to create PCB tool paths and how to engrave and drill them as I have a small CNC machine and want to create something similar?

[@WEGSTRCNC]

the new video for double sided PCB is in preparation so check our channel from time to time

[@thechriskelly12]

what type of toolpath is used for engraving? I See you use pockets for holes?

[@WEGSTRCNC]

yes, pockets for holes

[@thechriskelly12]

what type of toolpath is used for engraving though?

[@WEGSTRCNC]

just simple engraving in Cut2D...sorry I don't remember exact name

[@ikbendusan]

why is there already some green stuff on the board when you apply the liquid solder mask?

[@WEGSTRCNC]

because firstly you have to put the solder mask to the holes/paths to have really nice layer of the solder mask (without the bubbles)

[@stanislavtodorov8705]

how you prevent the bit from wobbling axially when you use the spring. I mean the bit and the spring are not fully tight in the chuck so they can move up and down correct?

[@vitor900000]

double point bearing... exactly the same thing you use in a 3D printer axis... you have one bearing on each side of the axis so it cant move. like this: (::)==[]====[]==> spring: (::) bearing: [] drill bit: ====>

[@vitor900000]

@Ali idk... I search myself and couldn't find it too... What i know is what its supposed to do. Its made to protect the piece if the CNC machine accidentally applying too much feed force. While the piece will still receive more feed force the force will be divide with the spring and will be applied smuttier instead of a spike.

[@hmartirosyan]

How that PCB holds itself in 5:02?

[@WEGSTRCNC]

if you check it very carefully you can see small bridges betwen the PCB and the other part

[@tuanat510]

how did you tin the PCB? which chemistry did you use?

[@rich1051414]

AFAIK, it is tin dissolved in hydrochloric acid. The tin in solution swaps places with the copper, tinning it.

[@hernandeserick7320]

The quality is impressive. what is the last chemical used?

[@CofeeAuLait]

Wow, as an engineer I hope someday I'm able to work with a company capable of making quality, just like this.

[@nickr8613]

I am quite jealous!!!! that looks amazing. i was hoping i could get some advice. i purchased the white variant of that paint. exposed to to an led array i made of 99 uv 390nm leds bought on ebay, and left it on over night. in the morning half of the uv paint stuck to the transparency and it was not fully cured. what am i doing wrong?

[@WEGSTRCNC]

Maybe the layer is too thick or weak power of the UV radiation. We use 60W UV lamp.

[@jeanyves5380]

Hi and thank's for your video. Too easy because simple side. But your milling and drilling methods seams to be well improved and reliable. I'm beginning the tasks of "electroplating through holes" at home. With my CNC i'm just drilling holes as a first operation. I etch with the paint burning method using a laser.

[@SuperVideoOtvet]

[@aaronespino2017]

hello, how about, an excellent job, a question, what do you put on the board so that it becomes green and what function does it have?

[@jasperdavis2433]

This layer is know as Soldermask. It is thermally resistant and prevents solder from sticking to anything other than the leads. This specific solder mask is uv-cured and can be found on amazon.
