Construct circuit board

Week 7

Title of the project:  Construct circuit board

Objective: Etching process

Content/Procedure:

1)    Print the design on transparent paper/stick paper 

2)    Stick the design on PCB board

         3) Etching process

                   4) After etching process

Analysis:

First step of etching is stick the design at PCB board and it should paste all of the carbon because it the way of current flow between component. Next, by using etching liquid the process is to erodible the cooper layer until left only copper line at circuit. Then, clean up circuit layer until look shiny and start process of drill a hole of pin component.

Conclusion:

Etching process is important to make sure all connection will connect between components. So, after this process it should be testing to check the connection of circuit in good condition.
