Making a Double Sided PCB with Plated Vias

This is just a collection of short clips outlining (almost) every step that it took to create a double sided PCB with plated through-holes for my UAV project.

I’m using the toner transfer method in this video which didn’t turn out too well because my laser printer doesn’t print dark enough over large copper areas. That is why there is some etching away on the copper ground areas. I should have used photoresist but it’s a pain to set up. Also, the alignment technique that I’m using doesn’t work perfectly and I actually scrapped the first board I made because the alignment was too far off.

Please turn on annotations. They will show all the steps.

  • If you’re using the acid etching process, you require to do the subsequent safe practices:
  • Always keep your acid in a safe cool place. Use glass containers.
  • Tag your acid and keep it somewhere out of the reach of children.
  • Tend not to discard your used acid in your home pipes. Preferably instead keep it and after you have some volume of used acid, move it to your recycling center/risky waste disposal establishment.
  • Apply safety gloves and air masks whenever working on acid etchants.
  • Be incredibly cautious when mixing and stirring the acid. Avoid using metal objects and you should never put the container on the edge of the desk.
  • When irradiating your PCB with Ultra violet, take an utter care to not have a direct visual touching the UV generating part of the insulator/chamber, or maybe employ unique anti-UV safeguard glasses. In the event that you must examine your PCB in the process, better stop the machine just prior to open it.
  • You need to wear safety goggles when employing the etching method and really do not look directly over the container of the chemical.
