PCB Rack
thingiverse
This rack, designed for use in etching circuit boards, enables efficient etching of multiple boards while utilizing a bubbler for increased speed. Crafted to accommodate three aquarium stones, it can be customized according to board length. To safely etch with Ammonium Persulphate, place the circuit board on the edge in designated slots, connect an air pump, fill the tank with the etchant, and initiate air flow. Ammonium Persulphate offers a safer alternative to Ferric Chloride, maintaining low toxicity and ease of disposal; simply mix it as a powder with water for consistent results without staining.
