CONCLUSION

This conclusion means Introduction to ESE subject is finish up for this semester. Thanks a  lot to Dr. Kamal, Mr. Redzuan  and Mr. Rasli. Throughout the semester was fun and full of joy but at the same time study  and practical is not being put aside. balanced between IQ and EQ is important to maintain our mind and also our body. Lecture given by Dr. Kamal and Mr. Rasli is needed to introduced us with this whole new ESE world. Practical with Mr. Rasli ensure that we can deal to make our own project in the coming semester. Industrial visit open my eyes and my mind how the situation inside the industry area, make us feel very anxious on what will happen to us in the future. Overall ESE class was awesome and thank you again to three great pillar that accompany us side by side throughout this semester. Hopefully we can see each other again next semester. :D

~ DIGITAL ELECTRONIC ~

sample of digital electronic

This week actually it was our last week for ESE subject. Therefore Dr. Kamal will brief us about the subject that we will take next semester which is Digital Electronic. WHY DIGITAL electronic? This because it has becoming part of almost everybody life. Digital Electronic can also be called the heart of electronic devices. This is because digital electronic control the function of electronic devices through it logic gate and binary number.

Digital electronic can be divided into three which are counting system, digital base-binary number and analog and digital signal. Logic level one of a finite number of states that a signal can have. Its usually represent by the voltage difference between the signal and the ground. In binary logic the two level are respond to binary 1 and 0.

sample of binary number

Binary numeral system or base-2 system represents numeric values using two symbols, 0 and 1.In this numeral system we learn on how to apply mathematics operation such as addition, subtraction, multiple and division to our binary number. We also had been given exercise to improve our understanding on this binary mathematics operation. Besides that, Dr. Kamal also touch a little bit about circuit automation and electronic design automation. Electronic design automation is category of software tools for designing electronic systems such as printed circuit boards and integrated circuits.

Thanks to Dr. Muhamad Kamal bin Mohammed Amin for the great introduction and planning for Electronic System Engineering throughout this whole semester.

THANKS A LOT :)

E+L+E+C+T+R+I+C

After an enjoy trip last week, we back to our workshop to continue what we left before. Finished with our circuit now we moved to electric part. In this session, im partner with Firdaus. We will assembly our own extension wire and pendaflour lamp. First, our lab instructor, Mr.Redzuan show us how to connect all the wire needed. He says we need to be careful because we deal with electricity that can cause serious problem if we play with it.

 

inside the plug

To make extension plug we need extension wire,socket and plug . To assembly inside plug box is not difficult but when it comes to plugr, here the real problem because the space is so small and we need to connect three different kind of wire which are earth, live and natural. We need to be precise and careful because it can cause shock circuit if not being assembly properly. For the plug the wire need to be attach to their own leg so that it can function properly. Earth, life and natural wire position can be check by the paper that attach together with the new lug header. From the front view, the earth is on top, life always in the right while natural on the left. If we can remember this position it will be a lot more easier to us to assembly those plug header. After connect all three component together, here our extension wire, DONE.

NEXT is to assembly pendaflour lamp. Mr. Redzuan tell us that we can assembly this type of lamp both parallel and series. First, we assembly using parallel connection. The tricky part is where are you going to connect the wire but lucky that Mr. Redzuan showed us first on how to assembly it. We can see the connection of parallel at the choke. After finished connecting all those wire, now come again the hard part to connect the wire with the plug. Same as before, the problem is how to connect the wire in small space but somehow we managed to connect it. Our, firs testing was fail because we misplaced the wire inside the plug header and after we identify the mistake and repair it our lamp can function properly. Next for the series connection, we need to change the choke and uses series choke because the current is different from the parallel. Besides the choke, we also need to connect it to series power supply if not the lamp will blow away. After tested and working well now we are really done.

This is our last class with Mr. Ahmad Redzuan bin Mohd Hanapiah, our lab instructor. Thanks to Mr. Redzuan for all the guidance, advice and hardship in teaching us. THANK YOU

Canon Opto(M) Sdn. Bhd (INDUSTRY VISIT) 7/12

The first camera by Canon

This week is so meaningful to us, SMJE students because we are having industrial visit at Canon Opto(M) Sdn. Bhd. on behalf our introduction to Electronic System Engineering study.The purpose of industry visit is to introduce us about industry.

This is my first experienced to visit a factory and see with my own eyes how they doing their jobs, their altitude, how company handle their workers, and work environment. I was impressing with how Canon Opto(M) hande their environment and they managed to win environment management competition and they certified with ISO 14001 which is ‘Environment Management’. 

Canon Opto Certificate

After a brief explanation about canon by the officer in charge we had opportunities to visit the site where camera and lens are being produced. Canon Opto(M) very strict about their workers altitude because they to need to maintain their products at optimum production. 5S altitude has been applied in this industry therefore their workers can have conducive working environment.

At the factory, I can see how the assembly the camera and manufacture the lens. Their work need to be precise because if their lens not smooth or not being assembly well it can affect their product and also Canon Opto(M) reputation. Inside the factory, their worker are working according to their section and each section have their own target to achieved during their shift. After finished visiting the both factory, we are having a meeting again with the officer because it is our closing ceremony. After the closing speech and exchange gift, its time for us to leaving Canon Opto(M)  after having such a great day here. 

Thanks to Canon Opto (M) for willing to accept us to do our industry visit here.After that industry visit, its help me expand my view about factory. It will be such a great opportunity if I can have my practical during final year here at canon because it environment and management were top class.

CIRCUIT MAKING !!! ^^

This week, it’s time for us to move on to make our own circuit after we had done with multisim and ultiboard in the previous class.  Everything needs its body and also our circuit. Its main body is it board and to make board for our circuit there are few steps need to be taken. Mr. Redzuan guides us on how to make our board based on PCB layout that had been printed. 

example of apparatus needed

First, we need to remove the insulating layer that cover up solder mask that are in green color. Then we paste the printed layout onto the board and then light the board by using UV light to print the circuit onto the board. In order to develop our circuit, we need to put the board into the developer sensitizer solution and its removes the unnecessary sensitizer. Part with ultraviolet print dissolves in the developer and the copper appear. 

Next, process will be etching. Etching is the process where the unnecessary copper foil part is being dissolves by using etchant such as ferric chloride. The acid is very harmful that when it get touch to our skin immediately need to be wash with flowing water, besides when the solution get to your cloths its take time to be taken off just like what happen to me. After done making the board with circuit we need, it time to drill so that we can solder our component. Placement of component is based on the PCB printed on our board. 

example of etching process

We need to be careful because the placement of component involves both sides of board, therefore we cannot doing any silly mistake that can wipe out our circuit  function. After all these process, our BOARD and CIRCUIT is DONE.

p/s: im sory mr.redzuan for making two board going waste (learning from mistake)
