Pretty much standard Frerric Cloride. It worked fine. Delivery was quick and price was reasonable. For all the pcb’s I make. This bottle will last a very long time.
This is THE BEST chemical to eat away exposed copper on copper clad board to make a pcd. you can draw you traces with a Sharpy, or, even better, you can buy LASER printer transparencyies, print a mirror image of your board, then place the transparency on the copper and iron it on good so all the tiner transfers. Anywhere covered is protected, weather you use permenant marker, toner, petrollium jelly, KY jelly... Well, im not sure about the last product for PCB, but its good to have on hand. LOL
J'ai utilisé le produit sur des plaques de laiton avec du vinyle pour protéger le motif. Ça très bien fonctionné. Prendre en note que la réactivité du produit dépend de la température ambiante. La gravure sera plus rapide durant les jours chauds.
