Objective
Content in first draft that detail, especially on summary of project, problems statement, and block diagram.

Content/Procedure

Problem Statment

The idea come when seen how the PCB board has been make. The problem statement come from the copper platting process that need stable pH value for getting good quality of PCB board. To control the value one machine has been used. This  machine control the chemical pH value in the mixer container. But this machine need an operator or technician to supervise because it is not fully automatic system.  From this problem we have decide to develop an automatic system to upgrading the current system. For example Controller main function is to make sure that the ph level constant on ph 7. if the value is less than ph 7 it will be add formalin to raise up the value to ph 5 and if the value more then 7 it will insert  Natrium Hydroxide  to stabilize the ph.

Objective

The aim of this project is to identify the most cost effective neutralization process which meets several criteria for water with a specific chemical composition. The objectives to reach the aim are as follows;

•          To study about the ph control system
•          To create a suitable system to control the pH value of the copper plate which offer a greater control system than the old PID controller.
•           To replace the PID control circuit with a new application of controller such as a basic stamp and ARDUINO. This is to expand the knowledge about a new controller in application for chemical industry especially in pH control.
•           To design an automatic pH controller system. This is a close loop system that will operate automatically according to the feedback received when the system is running.
