ALL ABOUT ULTIBOARD :)

What is ULTIBOARD??? 

 ULTIBOARD is......

the PCB layout application of National Instruments Circuit Design Suite that assists us in carrying out the major steps in the circuit design flow. Ultiboard is used to design printed circuit boards, perform certain basic mechanical CAD operations and prepare them for manufacturing, It als provide automated parts placement and layout.

There are many procedure using the ULTIBOARD...You can read it and think for a while how to use it.

NUMBER ONE :~

Open the saved circuit file from the Multisim and transfer the schematic design to Ultiboard 10 by selecting Transfer >> Transfer to Ultiboard 10.

NUMBER TWO :~

Use the Save As dialog box to save the new ultiboard file to your Z drive. Click OK on the message box that appears.

NUMBER THREE :~

Accept the default trace width and clearance that is given when Ultiboard opens. Make sure that all fields are selected in the Import Netlist Action Selection window and click OK.

NUMBER FOUR :~

Select the Layers tab near the middle of the left of the screen. This lists the board layers and other useful elements of the board. Double clicking a particular layer sets that layer as active. Double click Board Outline from the list.

  NUMBER FIVE :~

Right click an edge of the yellow rectangle and select Properties from the menu that appears. Under the rectangle tab set the width to 2000 and the height to 1500. Click OK and notice that the yellow rectangle become much smaller. This rectangle represents the area of the circuit board in which all of the components and traces must fit.

NUMBER SIX :~

The next step to PCB design is to layout the components. Double click the checkbox next to Ratsnest in the layers list. This remove the yellow lines that connect all of the components together and simplifies the picture.

NUMBER SEVEN :~

Begin placing the components inside the yellow rectangle. Notice single brown lines coming out of each component. These are Force Vectors and they point to the most efficient place to put the component based on its necessary connections. Use this as a guide for placement, but be careful because Force Vectors would ideally have all of the components stacked on top of each other in the middle of the board.

NUMBER EIGTH :~

The next step is setting up the routing parameters for laying out the copper trace. Go to the Netlist Editor by selecting Tools >> Netlist Editor. This tool keep track of all connections between pins on the board. Each set of pins connected together are referred to as a Net. Use the dropdown menu in the Netlist Editor to view the different Nets n the board. The tabs in the Netlist Editor provide different information and option for the selected Net.

NUMBER NINE :~

To prepare the Nets for routing select the first Net from the list. Select the Misc tab and check the box next to Copper Bottom. This tells the Autorouter that this Net can be connected by palcing trace either on the top of the board or the bottom of the board.

NUMBER TEN :~

In this case it is the best if the Autorouter can use the top or bottom layers for all of the Nets. To save times select the Nets tab from the group of tabs at the bottom of the screen. Right click one of the rows and choose Select All from the menu that appears. Click inside one of the cells in the Routing Layers column. Check the box next to the Copper Bottom in the window that appears and click OK. 

NUMBER ELEVEN :~

The board layout is ready for the Autorouter. Start the Autorouter by selecting Autoroute >> Start/Resume Autorouting. The Autorouter should only take seconds to place traces on the board. Notice that there are green and red lines that appear. The green lines represents copper trace on the top layer of the board and the red lines represents the copper trace on the bottom layer f the board. 

NUMBER TWELVE :~

It is important to cleanup and check the work of the Autorouter after use. Excessive bends and sharp angles in the traces greatly increase the chances of board failure during manufacturing and use. Take some time to look through the traces and get a feel for dragging traces into more appropriate shapes and angles. The Autorouter is never perfect and there are always traces that can be cleaned up.

NUMBER THIRTEEN :~

Once you are satisfied with the traces on the board Save and Close the design.

And one more thing that attracts me is the this program will show us the 3D figure of the circuit that we designed. Awesome!!!!

Thats all...I hope everyone will take some time to read this entry...ARIGATO!

CIRCUIT ON COMPUTER????THINK ABOUT IT....

 MULTISIM AND A LITTLE INFORMAION ABOUT ULTIBOARD...
HOPE YOU GUYS LIKE IT!!!

Ehem...Ehem....

Here is the new entry....

In this entry I will tell you guys about my recent Introduction to Electronics System class.

On that day all of section 2 students have to go to the Electronics Workshop.

There is a lot of computers in that workshop but not all of the computers can working.

First thing that we do in the workshop is we are briefing by Dr. Kamal about the assessment on the reflective journal that we have to do every week.

There are some papers that have been distributed to us.....

First...

OVERALL ASSESSMENT CRITERIA

 On this paper, there are the criteria that students need to follow to get good result. 

In this subject, the thing that will be judge is the reflective journal, practical, presentation and also attitude.

THE SECOND THING THAT WE GOT...

Dr.Kamal mostly focus on the reflective journal that day. This is because many of the students do not really understand what actually needed to write in this journal.
Because of that Dr. Kamal give us the booklet explaining about the reflective journal.

Actually, there is a lot thing that Dr. Kamal has given to us but I think I should stop here and start
writing about the second session in this class which taken over by Mr. Redzuan...

In this session, we are learnt about construct a circuit in a computer.
The software that we use are  NI Multisim 10 and also Ultiboard.

FIRSTLY, I WILL TELL YOU GUYS ABOUT THE MULTISIM...

NI MULTISIM 10!

When you enter this software, you can see an empty space which specially design for the user to construct a circuit on it.

THE EMPTY SPACE FOR DESIGNING THE CIRCUIT

Let I explain a little about the Multisim. This software integrates two programs that is a circuit schematics editor and a circuit simulator. The schematics editor allows us to build a virtual circuit by connecting various electronics components. Basically the user draws the schematic of the circuit to be analyzed. 

Before we start constructing the circuit. We are given a simple schematic diagram that we have to design in the software.

THE SCHEMATIC DIAGRAM THAT GIVEN TO US.

 Mr Redzuan teach us how to use the software before we try it by ourselves.

He explained the whole thing about how to construct the circuit in the software.

MR REDZUAN AT THE FRONT EXPLAINING ABOUT THE SOFTWARE.

The first thing we have to know is the toolbar.

THE TOOLBAR

From the toolbar, we can choose the icon that we need.

Here, in the menu icon, we can choose the components selection menu.

In this menu, we will choose the components that we need. 

We also can get the components icon just by clicking the left button of the mouse.

THE COMPONENTS SELECTION MENU

In the Component Selection Menu, set “Database” to “Master database” and “Group” to “Sources.”

 We can choose the type of the components and the value of the components from here. After that, we can just connect the components by a wire.

THE CIRCUIT THAT HAVE DONE

 Alhamdulillah...

I already finish constructing my circuit...

And alhamdulillah again when I RUN it, it does work.

The LED did lighted.

FUHH....

But one more thing that I forget....

From the picture, we can see there are some symbol of the components have blue colour while the others is black.

Actually, the components with blue colour represent the real components while the black colour represents the virtual components. When the circuit in the Multisim software imported to the Ultiboard software, only the real one will be appear there whereas the virtual one cannot appear in the software. In this case, we need to change the components type in order to complete the circuit in the Ultiboard. Just double clicking on the components in the Multisim and choose the real one. And then the components will appear in the Ultiboard circuit.

But, be careful. Make sure that the value of the components are the correct one.

I think thats all....

We are not done yet with the Ultiboard...

Therefore, I will stop here and will comeback soon with more story on Ultiboard...

BYE2...

COMPONENTS.. :)

COMPONENTS.....

Assalamualaikum...

             Arigato gozaimasu....               

Hehe...

And...Happy Reading....

 In this entry, I would like to show many components that we, SMJE students have learnt before with Mr Redzuan. Hmm...actually, I am a little bit suprise because our lecturer have been changed that day. Where is Dr. Kamal???All of the students keep wondering about it. We are waiting untill Mr Redzuan tell us about the truth that he will teach us for seven weeks and after that the lecturer will be change again...Hmm...Interesting...

Back to our topic...

COMPONENTS!

We are given many components on that day...AND

The FIRST COMPONENT IS...

RESISTOR

there are two types of resistor :~

Through Hole Resistor

 and

SMD Resistor

 That day, we are not only study about the physical of resistor. We also study about how to calculate the value of resistor by their colour code.

The table in FIGURE 2 shows the colour that represents certain value. This color code will help us to calculate the value of the resistor. As we know, the resistor have their own specific color. We just have to know what the color and the value represent by the color. Then we can calculate it by a simple calculation.

Value of resistor based on color code calculation

That is for through hole resistor...

For SMD resistor...

They have their code on their body...

As you can see before, the picture...

Now, the difference in determining the value of SMD resistor...

The way to determine the value of SMD resistor

See the picture carefully, we can see that SMD resistor use some code represent their value. We can determine the value by their code on their body.

Now, the SECOND COMPONENT IS....

CAPACITOR

here are TH CAPACITOR and SMD CAPACITOR:~

This is through hole capacitor

 

Capacitor is differ from resistor...capacitor did have negative and positive terminals...we can determine the polarity by the legs and also body...

Negative and positive terminals

From the above picture, it shows that the shorter leg represents the negative terminal and the long one represents the positive terminal.

Negative and positive terminals

From the above picture, we can determine that at the grey colour side on the capacitor's body represents the negative terminal.

SMD CAPACITOR

The above figure show the other type of capacitor...which is SMD Capacitor.

SMJE STUDENTS ALSO HAVE LEARNT ABOUT THE WAYS TO DETERMINE THE VALUE OF CAPACITOR

The first thing, the value of capacitor can be determine by the color code same as resistor but there is some differences between them.

Capacitor color code

Diagram of capacitor

The three figure above show the table of color code, the diagram of capacitor with specific color and also how the we can get the value of capacitor by their color code.

The SMD CAPACITOR also have their own speciality in determining their value. We can determine their value by the code presented on their body.

This is the example of how we can determine the value of SMD CAPACITOR by their code.

Overall, exactly, the value that we determine is not the accurate value of the components. We can have the accurate value of these components by using the multimeter.

Digital Multimeter

The above figure shows the example of multimeter that is used to get the actual value of components.

Hmm...I think thats all that I can share with you guys...

Hope this entry will give some knowledge to you all....

And also as a reminder for me...

Hehe...

See you guys in the next entry..

TATA

UTMKL???

02 SEPTEMBER 2012 - The day I step my my feet on University of Technology Malaysia, Kuala Lumpur (UTMKL). I feel very excited and at the same time I wonder if I can survive untill I graduate? Hmm... It is not easy to make a right decision. Especially when it related to our life. But I need to be strong so that I can survive untill the end. Fighting2!!!!

BANNER WELCOMING THE NEW STUDENTS :)

On the same day, in the evening, we, all of the new students need to get ready for the orientation day. Wah! So fast...hmm...actually, I feel so tired travelling from my home town to UTMKL. It takes 2 hours to arrive here...you know??? It is very tiring but I try to follow the activity arranged for us. During the orientation week, I am suprised because majority of the student does not choose the coarse that they have got. Hmm...how can it be like that. I feel so curious...I thaught all of students here did choose the coarse.

Hmm...I think there is something missing in my writing. Oh! The coarse! Actually, in UTMKL, there is two coarses for degree students. They are Mechanical Precision Engineering and also Electronics System Engineering. These coarses was managed under Malaysian - Japan Intenational Institute of Technology (MJIIT) Faculty. This faculty actually was new. Our batch is the second batch for our coarses.

Oh my goodness...!!!How can I forgot to tell you what coarse that I got!!!Ish3...I got the coarse that I want at the first place. I choose this coarse by myself. I got many support from my family and my friends to choose this coarse. My brother that also an engineer, in mechanical give me some guidance of learning engineering coarse. His wife, an engineer as well, electronics engineer give me many guideline to further study in this coarse.Therefore, I do not want to make them feel disappointed towards me if I cannot do my best. From that day, I remind myself to study hard from now on.

Yes!!!!!!!I can do it...!!!!

Do you know everything we want to do in our life, the first thing we should think is our parents. Is it good for me to do this? Is it bring benefit to myself? What can happened if I do this?What will happen to my parents?Ask yourself. This is what I am done before and now as well. I will always think of my parents in everything that I do. My spirit will always rising up when I think about them. I want to show you all one video. Listen it with your heart....

Hmm...I hope all of the readers will motivate themself and always remember of their parents in what ever they are doing. Parents sacrifices many things to make their children happy. We have to thank and appreciate their sacrifices.

11 SEPTEMBER 2012 - We, the students of Electronics System Engineering had attend our forth class, which is about Introduction To Electronics System Engineering. In this lecture, we are mentioned about many things. Dr. Kamal firstly want all of the students introduce about themselves. We have to tell our name and why we choose this program. Many of the students said that the coarse choose them not them choose the coarse. I realised that many of the students did not choose this program. Only minority student did choose this program. I am a bit impress about those who did not choose this program but still want to continue. This thing also make me want to put all of my strength to study well and graduate with praiseworthy. InsyaAllah.

Besides that, Dr Kamal also brief us about the coarse outline. He said that this subject are present pass class. Who attend every class will get good marks in this subject. So, do not play around with the schedule. Make sure that the attendance are fully attended. An addition, Dr Kamal also said that he will observe the attitudes of his students because it is included in the assessment of that subject.

Eventhough this class is not an english class but Dr Kamal always remind the students to speak in english as well as we can to improve our english. The communication skills is important for students in university to communicate with lecturers, international students and also important when we need to present our project. That is why many of lecturers want their students speak english with them. 

Haha....so why not we try speak in english???We should try...right?If we do not try, we will loss.THINK ABOUT IT!

Other than that, Dr Kamal also said that this subject require the students spend much time in the workshops. Analising circuit, components and also preparing a projects. Hmm...What kind of projects we will get???I do not know but it sounds great!We can create many things using the instruments in the workshop. Haha...Interesting...I hope that I can create something in the future....InsyaAllah.
