Design PCB PIC 16f877A

I'm using Proteus as it is easy to design a circuit and easy to use. Below is the schematic of the circuit.

 UV Light Process

• To make a PCB, the design need to be print on a transparent paper before it is affixed into PCB by going thru a UV rays process which will take about 80 second to complete. 

•  PCB will added with a liquid for etching process. 

• The ferric chloride powder will the mixed with warm water. 

• Then silica will detach and remove the layer by washed with clean water. 

•  the PCB will be insert into a developer liquid that will silicon oxide from the PCB.
