Safety Instructions
Solutions used in etching are CorrosiveEveryone must wear gloves and goggles when
working with such chemicalsWe will not be using in this classIs not recommended for use at home

What to Etch?
Need to design a circuit schematicWires will be the
copper that is not etched

Patterning PCB Boards
STEP 1: Print schematic on magazine paper with a laser printer(Suggestion)
Print on Laser printable Transparency
STEP 2: Clean PCB board with a wire mesh pad and rinse with water

Patterning PCB Boards
STEP 3: Iron the board 1 min and then on the design onto the PCB board for ~1 minute
(Suggestion) Iron for up to five minutes Or press for a minute or two

Patterning PCB Boards
STEP 4: Place the PCB into water and gently remove the magazine paper
(Suggestion) Print on Laser printable
Transparency using water to take off magazine paper is not needed. The print is transferred directly to the PCB Board.

Etching PCB Boards
STEP 5: Use a black permanent marker to lay out any tracks that need protection
STEP 6: Send to a lab and have the boards chemically etched.

Why Chemically Etch the Copper?
Able to form electrical connections between circuit componentsNo external wiresContinuous connections
