What is PCB etching tank?

Etch Tanks A self-contained triple process unit with built-in DEVELOP / SPRAY WASH / BUBBLE ETCH functions providing a convenient bench standing system. Connections are provided at the rear for drain and cold water requirements.

What is a etching tank used for?

The Printed Circuit Board Etching Tank, created in November 1993, aids in the creation of homemade circuit boards by enhancing and speeding up the etching process. The system is comprised of an acrylic tank, aquarium heating element with thermostat, and aquarium air pump.

Which solution is used for etching of PCB?

Currently used for print circuit board etching of solvents are iron (Ferric Chloride), cupric chloride (Cupric Chloride), alkaline ammonia (Alkaline Ammonia), sulfuric acid hydrogen peroxide (Sulfuric Acid + Hydrogen Peroxide) etching fluid, ammonium persulfate, sulfuric acid – chromic acid etching solution.

How do I make an etching solution?

Mix two-parts of diluted hydrogen peroxide with one-part muriatic acid. There you are, done! The hydrogen peroxide acts as an oxidizer allowing the acid to eat away the copper. Place your board to be etched in your new solution and watch it go!

How to make your own circuit board?

Take a printout of circuit board layout Take a print out of your PCB layout using a laser printer and the A4 photo paper/glossy paper.

Cut the Copper Plate for the Circuit Board Cut the copper board according to the size of the layout using a hacksaw or a cutter.

Transfer the PCB Print onto the Copper Plate Method 1: Iron on Glossy Paper Method (For Complex Circuits) Transfer the printed image (taken from a laser printer) from

Iron the Circuit from the Paper onto the PCB Plate After printing on glossy paper,we iron it image side down to the copper side,then heat up

Etch the Plate You need to be really careful while performing this step. First,put on rubber or plastic gloves.

Cleaning,Disposal,and the Final Touches for the Circuit Board

What is a printed circuit?

Definition of printed circuit. : a circuit for electronic apparatus made by depositing conductive material in continuous paths from terminal to terminal on an insulating surface.

What is a circuit board?

A circuit board is a piece of insulation that is threaded with conductive wires and similar components. When a power supply introduces an electrical charge to the board, it is distributed along these wires to different components in a variety of ways.
