That's a fantastic idea! I'll definitely give it a try next time. Thank you so much!

Iam using 130gsm photo print paper. Thank you.

Thank you

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

It's a USB to TTL converter.

I Am using glossy non adhesive paper. Here is the link to a similar paper amzn.to/44jJb95

Thanks ​@@ElectroRetro

Thanks for watching

flipping the board is good to evenly etch the board.

@@ElectroRetro thank You

0.2mm

Yes

Yes

Thanks

No, Inkjet wouldn't work. Must use laser printer.

👍🏼

Top layer need mirror print.

​@@ElectroRetro thank you so much 😊. Tomorrow I'll try it

@San_DIY 👍

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.

👍🏼

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

Laser printer

@@ElectroRetro Dear Sr,Can use brother hl 1110 mono laser printer?

Yes

👍🏼

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. I tried it. 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.
