Week 2

Title: Soldering the PCB board

Objective: To ensure the all component are connected in to the PCB board

Content/Procedure:

This week I continued on PCB development circuit by soldering the component after the PCB done the etching process. Here I encounter some problem on the board where it happen capacitor polarity which wrong install then re-install back in correct connection.

Result & Analysis:

Week 1

Title: Simulation circuit into the software designer

Objective: To simulate the  LDR circuit on the software engineering

Content/Procedure:

From this time, I already make the circuit development with etching the PCB of LDR controller. The duration for development took almost 2 week to make it complete PCB board with appropriate design on the board. Here I enclosed the simulation LDR circuit using proteus and rough PCB design progress in Protel 99 PCB Design

Result & Analysis:

Schematic diagram of LDR using proteus

The Bottom PCB design

This is the etching layout printed into the PCB board using laser print to print the layout and using acid. When the plate is immersed in acid, the bare metal, exposed by the lines of the drawing, is eroded.

Conclusion:

The circuits of PCB layout well simulate
