Directions

Immerse copper board in solution and agitate until etching action is completed. Ferric Chloride can etch up to a maximum of 100g of copper per liter of solution (.33 square meters or 3.5 square feet of 1 oz copper clad board). Etching process can be sped up by heating the solution to a temperature no higher than 55°C (135°F). If you require further directions for etching or making a printed circuit board, consult the positive photofabrication process guide available free from your dealer.
