IMPORTANT! Don't forget to: 1) paint it with a protective lacquer after soldering, or 2) coat it with some alcohol-dissolved colophony/resin before soldering, which doubles as flux, or 3) tin all traces with solder. Otherwise the bare, exposed copper traces will oxidize with time, their resistance will increase and it may cause a lot of weird issues due to voltage drops.
I had a thought. Would it make sense to drill the vias before etching? That way you might avoid liftoff of copper if your second side is a small copper ring after etching. Also, it would ensure that your print is 100% aligned. Also, instead of visual alignment, the via holes could be made to be alignment holes as well, so no eyeballing the print through light would be needed..
Very nice, if you were added uv mask, it would look professional, also can i do the same thing, just instead of using toner transfer method, im gonna use uv film?
Hi Electro Retro! Nice job teaching us how to make double-sided PCBs using this technique. Could you share the type/brand of solder flux you used, please? Seems very neat in contrast with the ones I have been using.
Nice. How much time in the etch bath? You showed 3 or 4 clips. How long did it take? And where can i get a drill and bits like you have with the proper size bits? I think you has .3mm bits?
The etching process typically requires a duration of approximately 15 to 20 minutes in my experience. However, it should be noted that when reusing ferric chloride, the etching time may progressively lengthen. Enhancing the agitation of the container during etching can assist in reducing the overall etching time. The drill bits were purchased from a nearby electronics store. Alternatively, one can acquire them through online platforms. The specific drill bit showcased in the video has a diameter of 0.5mm. www.amazon.com/Pieces-Polymer-Jewelry-0-1-1mm-Random/dp/B084T4PB1K/ref=mp_s_a_1_4?crid=1OOARF9JKZFN1&keywords=Pcb+drill+bits&qid=1688453567&sprefix=pcb+drill+bit%2Caps%2C393&sr=8-4
Do you flip the board when etching? I only did one-sided-pcbs until now and Iam wondering if I have to change my etching methode for double sided pcbs?

@@ElectroRetro oh one more thing is glossy paper got two type , one is glossy art paper and one is glossy photo paper, i have the one of glossy photo paper , this work too right? if yes then i no need to buy another 🤔
@@ElectroRetro recently i tried making a pcb at home I used a manual drill same as you for each hole it took around 10mins so how much time is it taking for you per hole. If it's quicker than me any suggestions would be really helpful
Previously I used a hand drill, it would take less than 1 minute to drill a single hole using a hand drill. Now a days I'm using a small dc motor with mini chuck.
Good morning, first of all, I would like to say that the tutorial with double-sided PCB was great. Could you put a link to the paper you used, as in the video it seems that the side where the laser printing goes is the shiny side? And if this paper is adhesive? Sorry for so many questions but after so many mistakes making PCB printing, watching your video was a salvation at the end of the tunnel. Thank you very much in advance.

Please never use any type of scrubber to clean pcb. You will get super clean pcb by 1. Clean it with soft sponge and dish wash liquid (to remove oil and dirt films) 2. After drying with clean cloth, " use plasto pencil eraser " and rub the copper clad You will get it super cleaned. 3. Never touch copper side again with bare hand. Try and reply me.
@ElectroRetro absolutely !! You will get very pure copper exposed. I tried it. Will result in better toner adhesion I used white plasto eraser (used to correct pencil )

Yes this video is what my doctor prescribed. A different kind of therapy lol.
This has got to be the easiest way I have seen yet.
very innovative, the copper wires as vias

One of the best toner transfer PCB's I have seen! What paper is used in this video? Maybe photo print paper?
Iam using 130gsm photo print paper. Thank you.
Do you flip the board when etching? I only did one-sided-pcbs until now and Iam wondering if I have to change my etching methode for double sided pcbs?
flipping the board is good to evenly etch the board.
@@ElectroRetro thank You
is very nice, can tell me about the width of traces that be used, thanks.
0.400mm

Does normal printer is okay? We dont a printer so i need to go to printing shop
No, need laser printer.
Beautiful! I'm curious what this circuit was for?
It's a USB to TTL converter.
Smd design in SMD side changed in sample PCB 😢. It need to print with mirror????
Top layer need mirror print.
@@ElectroRetro thank you so much 😊. Tomorrow I'll try it
@San_DIY 👍
If you need metalized holes ?

how about join 2 pcb.??
i`m not see on video
Buy yourself an electric jigsaw and a metal saw, it will be much easier to cut textolite. Even better than on a minicircular saw.
Is it okay to print the circuit design on inkjet printer?
No, Inkjet wouldn't work. Must use laser printer.
where is the file to cut rought edges? i cant see the link..

Sir,can we use zero pcb board for doing with double sided soldering
Yes
prefet & amazing. well done 👌👌👌👏👏👏
Please I'm a new student
What app can I use to do this
And I'm in Nigeria, where can I get the copper plate
You can use easy eda for circuit design.
Quality work👍
Thank you
Is it necessary to mirror the top layer?
Yes
can i download the schematic eagle sir?
That pcb is for demo. Its not perfect. It has some errors.
@@ElectroRetro but we still want to try, please send the link of PCB
How much time is it taking to you too make wholes for the entire pcb
It depends on the size of the pcb
@@ElectroRetro recently i tried making a pcb at home I used a manual drill same as you for each hole it took around 10mins so how much time is it taking for you per hole. If it's quicker than me any suggestions would be really helpful
10 min is too long. It won't take that long. You should replace your drill bit or you can use a mini rotary tool.
@@ElectroRetro oh how long is taking for you drill a single hole? And what drill are u using
Previously I used a hand drill, it would take less than 1 minute to drill a single hole using a hand drill. Now a days I'm using a small dc motor with mini chuck.

" use plasto pencil eraser " and rub the copper clad

Thanks for the tip. I will definitely give it a try. One doubt, does this method remove oxidation on the copper surface?
@ElectroRetro absolutely !!
You will get very pure copper exposed.

Will result in better toner adhesion
I used white plasto eraser (used to correct pencil )
Thank you so much. I tried it. I got very good result.
