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

Preparing To P.C.B Board Entching

Objectives:

1. To prepare the circuit before
2. To make the P.C.B layout
3. To confirm that p.c.b solar layout
4. To make sure that p.c.b layout correct before do the etching

Procedure:

1. Here we have two choice. First, design the P.C.B by using software(Diptrace). Second, by using p.c.b layout from magazine.
2. To facilitate the design process of making p.c.b circuit layout, there are examples in the magazine was edited according to the size needed   
3. Original size and shape to the left magazine during edit on the p.c.b circuit sizes must follow to determine what was in the magazine. This is to prevent the components such as IC can not enter.
4. Width of the circuit that edit or sketch is 38 mm. while the circuit is 51mm long.
5. After the editing process is made, the circuit print on the A4 paper. Double check circuit.
6. If the circuit was not clear print, color the circuit to avoid the circuit is broken when the circuit is print on transparent
7. After this process is complete then print paper had made ​​photocopy to the transparent paper.
8. If there have a problem on the transparent paper repeat the process for the second time. 

conclusion:

After all this process is made and has resulted in a complete p.c.b layout and all according to what is required then the next process can be done. The process is the process of etching the solar power   circuit
