Hi, which paper do you use for the transfer? Thanks for the instruction.

[@TeknoTrek]

I use colored shiny paper that children usually play with. Thanks for your comment!

You did not mention about the proportions of acid and chemicals that you used. Nice but incomplete.

[@TeknoTrek]

Hi there! Thanks for watching my video. You're absolutely right-I didn't go into enough detail about the proportions of acid and chemicals to use. It's crucial to handle these materials carefully, as incorrect proportions can pose health risks and potentially damage the PCB. Hydrochloric Acid and Hydrogen Peroxide Ratios The amounts of hydrochloric acid and hydrogen peroxide you'll need depend on factors such as the size of the PCB, the thickness of the copper coating, and the ambient temperature. Generally, smaller PCBs require smaller mixtures. For exact ratios, you can experiment or seek advice from experienced hobbyists. Example Ratios For starters: Try a mixture of 1 cup of hydrochloric acid and 1/5 cup of hydrogen peroxide. For faster etching: You can increase the amount of hydrogen peroxide. However, using excessive hydrogen peroxide can cause the copper to overheat and lead to undesirable results. Important Notes Safety: Hydrochloric acid and hydrogen peroxide are toxic and corrosive. Always wear gloves, goggles, and a mask, and work in a well-ventilated area. Experience: If you're new to this process, start with a small piece of PCB for your first attempts. Environment: Dispose of the used chemicals in an environmentally friendly manner according to local regulations.

Excelent tutorial!!! What pliers do you use to cut the pcb? Thanks!!!!

[@TeknoTrek]

Thank you so much for your kind words! 😊 The pliers I used to cut the PCB are actually tin snips, which are typically used for cutting sheet metal. They work really well for trimming PCBs too! Let me know if you have any other questions. 👍

@@TeknoTrek Thanks a lot!!!

[@johnhicks692]

I have used muriatic acid and hydrogen peroxide. Can't remember the proportions.

[@TeknoTrek]

Thanks for your comment! A good starting point is 1 cup of hydrochloric acid (muriatic acid) and 1/5 cup of hydrogen peroxide, but the proportions should be adjusted based on the size of the PCB. Always handle with care and use safety gear! 😊

przed laty bawiąc się w elektronika wykonywałem estetyczne plytki drukowane ,używając do maskowania FIOLETOWEGO tuszu kreslarskiego, płytka musiała być dokladnie przeszlifowana drobnym papierem ściernym i odtuszczona,najlepiej denaturatem.

[@TeknoTrek]

Dziękuję za podzielenie się swoimi doświadczeniami! Używanie fioletowego tuszu kreślarskiego brzmi jak świetny pomysł na estetyczne płytki drukowane. Dokładne szlifowanie i odtłuszczanie to naprawdę kluczowe kroki w uzyskaniu dobrego efektu. Miło słyszeć takie wskazówki od osoby z doświadczeniem! 😊

A laminator works better than an iron imo

[@TeknoTrek]

Absolutely! A laminator distributes heat more evenly, making the process more effective. Plus, being able to control the temperature is a huge advantage. With an iron, the heat doesn't always distribute evenly, which can increase the risk of mistakes.

6:20 i am nor sure, for this. No one doing this.

[@TeknoTrek]

At 6:20, you're right-it’s not something everyone does. It’s entirely optional, but I personally prefer doing it this way because it gives me more control over the process. Thanks for sharing your thoughts! 😊

[@smidjepeter]

everyone has a laser printer??

[@TeknoTrek]

Not everyone has a laser printer, and that's a great point! If you don't have one, you can use a local print shop to print your design on glossy paper. Just bring them the file, and they can help you out. Thanks for bringing this up! 😊

[@6pack1204]

I have ! They are not expensive and better and cheaper than an inkjet.
