Hi Everyone.
I've normally been using pre-sensitised PCBs that you expose to UV and then put in developer. However I've decided to try and use the Laser printer=>transfer=>etch method using Hydrochloric Acid and Hydrogen Peroxide.
I have plenty of peroxide, and bought hydrochloric acid today, the smallest amount I could buy was 5L.
For protection, I wore jeans and a long sleeve shirt, rubber gloves, and safety goggles that have a foam sealing ring around the eyes.
I opened the bottle of acid, and it started fuming immediately, a thick white mist came out. This was unexpected and I immediately sealed the container.
Is the acid perhaps too strong or something? The fuming scares me, has anyone else had a similar experience and gone through with the etching process?
