Etch a Circuit Board

How to Etch a Circuit Board(1)

Have you ever wanted to make a circuit board at home? Now you can, for use in all types of homemade electronic components

Steps

Design

1.Have a procedure in mind before attempting the task that is to be accomplished, and a good design is always needed.

2.Draw the circuit schematic on either graph paper or a simulation programs such as MultiSim or Eagle CAD. The schematic should contain a detailed description of all parts, as well as easy to follow connections, keep in mind that a basic form of the schematic will be drawn on the circuit board. For help drawing schematics, please visit: Open Circuit Design

3.If a simulation program is being used, test the circuit thoroughly in the simulated environment. If no simulation program is used, it is necessary to assemble one or more prototypes of the circuit on a breadboard. Breadboards are very easy to use, and allow one to view the results of a circuit in real time without the need for solder or creating permanent etches. For help with breadboards, please visit: Iguana Labs

4.Make sure the circuit functions on the breadboard, or in the simulation software.

Etching

A non-metallic basin that is deep enough to submerge the circuit board • Various beakers/containers for mixing

Goggles

Vinyl or Latex gloves

A device used to agitate the circuit board (a stick)

Hydrochloric Acid (Muriatic Acid)

Hydrogen Peroxide

Ethanol

Acetone
