FYP S2 WEEK 9

Tittle of activity :

PCB fabrication...hardware step development

Objective :

     PCB Drawing: PCB drawing is designed using Protel DXP 2005. Once the PCB layout has been correctly design, it is now prints out the layout on the A4 size transparent OHP paper. Note that, two types of printers are allowed to print the PCB layout, one is laser printer and the other is carbon type of printer such as Photostat machine. Inkjet and dot matrix type of printer will not work.

Content/procedure :

1.    PCB Cutting: Cut photo PCB size according to the film size.

2.    PCB Photo Etching: Expose the photo PCB in photo etching kit for 8-10minutes.

3.    PCB Developing: Wash the PCB using PCB developer (white powder) for 2 min.

4.    Acid Etching: Etching is a process that removes materials from such us unwanted copper from the PCB surface to achieve circuit design requirements. The etching process used in this project is called chemical etch or pattern etch. 

Result:
