Store between 16°C and 27°C (60°F and 80°F) in dry area. Store in plastic container. Do NOT store in metal containers.
For best results, follow the procedure below. If further directions for etching or making a printed circuit board (PCB), consult
the photo fabrication process guide available free from your dealer.
1. Fully immerse copper board in solution.
2. Agitate until etching action is complete.
To speed up etching
Warm the ferric chloride solution between 35°C to 55°C (95°F to 131°F).
ATTENTION! Do NOT heat ferric chloride solution above 55°C (131°F).
NOTE: Dilution is not recommended.
