Tools

• A computer software that supports PCB formation• Etching acid• A single/double sided blank PCB• A drill• Tin alloy• Welding ironAll the above can be purchased from RAM and El Nekheali

(Down town)• An iron• Glossy paper• Lazerjet printer

Procedure• Draw the schematic• Convert to PCB view• Print the PCB on a Glossy paper • Put the Glossy paper on the PCB facing it and tape it with non

melting tape• Iron it for 2 min• Remove the Glossy• Drill for halls• Etch in an acid until no metal is left except under the printed circuit• Expose the metal left by scratching the lines• Weld the components on the PCB
