2. Tools A computer software that supports PCB formation Etching acid A single/double sided blank PCB A drill Tin alloy Welding iron All the above can be purchased from RAM and El Nekheali (Down town) An iron Glossy paper Lazerjet printer

3. 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
