WEEK 14 (2)

TITLE OF ACTIVITY : Industry day's

OBJECTIVE : Presentation of the project and tested by the assessor.

METHODS :

- Prepared and completed all equipment.
- Last observed on the project and take print posters.



RESULT :
- Final plan is to review the project and prepare to be judged by lecturers evaluator.

ANALYSIS :
- At first we examine the input and output readings to the project, there is no problem. Then we examine the perspectives and we found the crack. We repair cracks using liquid glue. Once finished, we examine the contents of the grammar in the poster. Once everything is finished we make final preparations to bring the materials necessary for the Industry's day.

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 :

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 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.

PCB COMPONENT BEFORE PRINT OUT

PCB CIRCUIT

ANALYSIS :
- 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.

WEEK 7

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.

WEEK 6

TITLE OF ACTIVITY : Pulse width modulation.

OBJECTIVES : 
-To understand the basic operation of the inverter.

METHODS :
-Make observations about the sources and basic functions.
-Collect all the details fit.
-Search data sheets on the internet.

PIN CONNECTIONS OF SG3526

RESULT :
-More on observation by our gathering data.


Analysis :
-The basic operation of the power
inverter is illustrated in Figure 1.
The SG3526 alternately switches the
current through the 12-V windings of
a mains transformer, the two central
ends of the windings having been
taken together and connected to the
positive battery terminal (+12 V). At
each switching action, the direction
of the current changes and with it
the direction of the magnetic field in
the transformer core. The result is a
square-wave(-like) alternating voltage
at the 230-V side of the transformer.





CONCLUSION :
-Initial data collection is finally finished.

WEEK 5

TITLE OF ACTIVITY : Search at hobby kit, google, and software for our project.

METHODS :
-Finding the right software and materials used in the project.
-Installing the software for circuit sketch project.
-Provide additional material for the final work.

Perspex board

Software brand 6.3.0

RESULT :

-The software we are looking for is very suitable for the project because it eases the work of drawing the circuit and the materials we use are also suitable.

ANALYSIS :

-When looking for software on the Internet, we stalled because we do not know how to download it. So we plan to find friends who have the necessary software. Then, we need to go  Jalan Pasar, Pudu to get it because of this that we know there is supply electronic components.

CONCLUSION :

-We use other methods to get the software and find materials place a bit far.
