Week 6 : The Layout and Etching


The layout had been drew using Pad to pad software for design the circuit  and print out on the plastic sheet size A4. Then, that plastic will be iron  on PCB board so that the ink will be melt onto it surface.



The circuit then will be etching using etchant which is an acid, then unwanted part will be varnish away and leave only the wanted one.
