WEEK 8



Title of activity: Design PCB board for charge controller circuit 


After the conformation on the circuit I start to design the circuit by using Dip trace software for the main circuit and for LCD circuit. After design I go to the printing shop to print the circuit layout to the transparent paper, after that I attach and stick the circuit layout on the transparent paper to the PCB board. Then I use iron to make the ink from the transparent paper stick to the PCB board.

After the ink properly sticks to the PCB board I need to check if any broken connection of the line circuit layout and need to repair by using marker. After satisfied with the connection I start to etching the PCB board. After etching I need to check the connection again to make sure no broken line and no connection are connect each other. After several of etching that satisfied me I start drill the hole by using driller to put the component on the circuit.
