The bottle contains 100ml of reagent grade high quality Ferric Chloride (FeCl3) liquid solution prepared at 40% (w/v) ratio as per the PCB etchant standard.

Steps:

1. Immerse the copper board in the ferric chloride solution. Agitate the solution gently to ensure even etching. This process can take anywhere from 10 to 30 minutes
