Ei guys! Natutunan ko to noong lecture forum namin sa school tungkol sa paggawa ng PCB (yung mahahabang boards na ginagamit na kinakabitan ng ICU's). Although brief lang sya I guess eto rin yung steps.

Materials:

Ferric Chloride (etching solution)
Copper sheet

Steps:

1. print the PE pattern you want and paste it into the copper sheet
2. mask the part you wish to create
3. put it in the container with the etching solution
4. in minutes (unknown) matutunaw na yung unmasked parts
5. get it and wash in in cold water to remove the solution
6. There you go!
