P.C.B Board Itching For The Solar System

Objective: 

1. Preparing to construct the circuit by using P.C.B board
2. To make the arrangement of component before make a soldering

Procedure:

1. Photocopy the PCB layout (In Previous Report) in to  sheet using laser printer    
2. Attach the paper on the P.C.B board. The P.C.B. board avoid exposure to light.
3. Put transparent paper sheet and the photo-etch board into a UV exposure unit for 60 second.
4. Wash the developing using ferric chloride. Let the P.C.B in the acid and shake it till the circuit clear from copper that not needed on a board.
5. Transfer the PCB in to etching tank and do the operation for 4 minutes.
6. After finish on etching tank, scrub the P.C.B board using sand paper
7. Make sure the connection of PCB is in right continuity. 

Result and analysis:

• All the process of producing the PCB is done step by step
• To make sure circuit connected do the testing to circuit by using multimeter

Conclusion:

The method are used in this PCB process are essential so that no important steps are skipped. Skipping any of these may cause failure to the outcome of the project. The steps are done is to helped us troubleshoot the hardware and software if any complications should arise
