WEEK 13
TITLE OF ACTIVITY : Prepare and make touch-up the projects.
OBJECTIVE : To make the last steps before meeting with counsel for the explanation.
METHODS :
- Decorating a bit on the project.
- Checking the circuit assembly.
- remove materials that are no longer needed.
RESULT :
- Everything was going well.
ANALYSIS :
- This is the final touch. So we must be prepared in advance to check what should be.
CONCLUSION :
- Circuit ultimately we choose not pose a problem as the previous circuit.
WEEK 12
TITLE OF PROJECT : Buying additional tools to make projects and installations.
OBJECTIVES : For the final step of making the installation and show the adviser.
METHODS :
- We go to Jalan Pasar Pudu to get the tools needed. In planning we want to buy some tools such as cooling fans, motors and also buy PCB stand.
RESULT :
- Once we get what is planned, we continue to make the installation as to save time.
ANALYSIS :
- material we buy is to complement the output and while fans are additive to cool certain components.
CONCLUSION :
- The materials we need are very important.
- We need to quickly set it up as advisers would like to see the work of the project.
WEEK 11
TITLE OF PROJECT : Soldering the component on PCB.
OBJECTIVES : Soldering is the process of soldering components to circuit attached to the PCB.
METHODS :
- The equipment required is solder, solder paste, soldering iron & stand.
- Eye soldering iron should be cleaned before use.
- Enter the component on the right.
- Heat up the soldering iron and solder to the component.
- Cut away excess components using cutter.
RESULT :
- All materials can be prepared and caused the job step can be made smoothly.
ANALYSIS :
- After the steps before this work is completed, the next process was done by performing a soldering components. Replacement parts must be correct before soldering to unforeseen happens.
CONCLUSION :
- Making soldering should be careful because it can cause burns on yourself and also can damage components if negligent.
- It should be efficient to do so soldering is not a problem.

WEEK 10
TITLE OF ACTIVITY : Iron on PCB.
OBJECTIVE : To produce the PCB circuit and allow the next step to be done.
METHODS :
- Prepare : Clothes iron, metal polish solvent and photocopy or software image of circuit image.
- Photocopy the circuit image onto the non-glossy side of a sheet of Iron-On-PCB. the print out must be mirror of the original image.
-Clean copper boards with metal polish solvent
-Place the Sheet face down on the copper clad material and iron it with an iron set halfway between two and three. continue until the copper is hot and the image has gone dark all over.
After cooling the film is peeled away to leave the image. Etching is by the normal method with ferric chloride or ammonium persulfate in a tray or bubble etch tank. And after etching and drying, remove the resist with thinner solvent. the blue resist is removed away leaving the copper circuit tracks.
RESULT :
- Do need to follow the rules because it may just not be as missed a method prescribed. With the instructions provided, then it can be done well.
Analysis :
-Lots to do during the process did work Iron-On-PCB. After obtaining the appropriate schematic concept of the project , list types of components to be used . Make sure the components purchased to work properly , especially components that are expensive, difficult or major components found in the circuit . Then need to use computer software such as Proteus , Eagle , PCB Wizard and so on. This process involves the use of chemicals. need to comply with security measures , rules of use and disposal of chemicals. Etching process is done to remove the copper layer ( copper layer) that is not required on the PCB using liquid etchant . Chemical ferric chloride ( FeCl3) is used to produce a highly corrosive liquid etchant . be careful when handling these chemicals . The duration of this process depends on the solution concentration , solution temperature and the size of the PCB is produced. Once everything is finished , the PCB need to rinse.
CONCLUSION :
- Advantages of this technique to produce large quantities of PCBs for Transparency requires only one mold.
- Must comply with all instructions, manuals and process work carefully to avoid mistakes and loss of PCB damaged or poor quality.
WEEK 9
TITLE OF ACTIVITY : Making the circuit in PCB software.
OBJECTIVE : To make the move early work before soldering and Iron-on-paper.
METHODS :
- We use Eagle Software for drawing circuit.
- We talked with other colleagues to improve the situation and appropriate to the component.
RESULT :
- From the discussions that we have obtained in making the circuit is very good.
ANALYSIS :
- Too much can we get the software and the software we chose Eagle because it can we understand.
CONCLUSION :
- Computer software can save time and produce PCB production higher quality compared to manual methods.
- We need to get the software and learn the application as each different software methods of use and features.

WEEK 8
TITLE OF ACTIVITY : Looking for a new project circuit and the same concept.
OBJECTIVE : For drawing sketches of new projects.
METHODS :
- We find the concept of project in the magazines, the Internet and the resources in the college library.
-
RESULTS :
- The results we have obtained from the Internet where it is very easy to understand but with the output section. At the front of the output in the diagram below we have changed a few changes.
- This layout was similar to the theme of our project where input is 12V dc and 230V ac output is about. with reference we sketch a little change on the output and is still in draft. Output is the output was only in 24watt.
CONCLUSION :
-We had to buy new components.
- Doing work such as making the current study and make a new sketch in the software.

TITLE OF ACTIVITY : Construct the component.
OBJECTIVE : To see the function.
METHODS :
- Make installation of components in bread board.
- Make a test current into the circuit.
RESULTS :
- Our attempts failed because no combustible components and can not be used again.
ANALYSIS :
- We were able to identify the actual causes burns and some components can not be used again, but we make the assumption that the initial problem occurred starting from the input.
CONCLUSION :
- Current plans call for the existing circuit can not be worn again and plan to use the concept of the other circuits.
