 CHAPTER 1

INTRODUCTION TO INDUSTRIAL TRAINING

1.1 Introduction of Industrial Training

The Industrial Training module is a main component in the learning curriculum for the Polytechnic
of the Ministry of Higher Education (MOHE). All students must complete industrial training as a
partial fulfilment of the requirements for the Diploma in Mechanical Engineering. This program
exposes students to real-world situations in the field of mechanical engineering and serves as a
prelude to the working world. For session II 2023/2024, the industrial training performs for 20
weeks starting from 29 January 2024 until 14 June 2024.

With the guidance of lecturers and UPLI PBS, I sought and get hired at Amkor Technology
Malaysia Sdn Bhd. I was assigned to the Department of Manufacturing Engineering B (MEB). I’ve
got learned and explored along with Facilities Department (FD) and Machine Shop Department
(MSD). The working culture on this company is not only in the field of engineering but mixed with
the admin part to learn various fields.

11
 1.2 Objective of Industrial Training

A polytechnic's target is to figure out successful, excellent, and responsible students through
industrial training. The Industrial Relations and Training Unit (UPLI) has defined a number of
industrial training objectives that must be fully attained by the students through training to achieve
that goal. Among those objectives are the following:

1.2.1 Expose Student to The Real World-Working Experience

Students will gain more knowledge about their actual line of work. Additionally, they will discover what
steps they must take to complete their assignments. This will enable the students to integrate easily
into their professional environment and meet demands upon the end of their course.

1.2.2 Adapting to the company's rules.

During their industrial training, students must follow through all firm rules and regulations, including
those related to safety, discipline, order, and any laws established by the company. Through this, it
shall be simpler for the students to become familiar with all the regulations and enter the workplace
without any issues.

1.2.3 Evaluate Student Own Abilities.

Students will be able to evaluate themselves based on training that has been carried out for five
months in an organization. Through this self-evaluation, students can evaluate through the tasks
performed during the training by highlighting the characteristics of effective leadership and with the
initial exposure that students get, students can also give ideas to help improve the organization. In
addition, this is recorded as a confidential item in the industrial training book that will be reviewed and
filled in by the supervisor after the industrial training is over.

12
1.3 Importance of Industrial Training

It is common knowledge that the purpose of involving Industrial Training into Polytechnic
syllabuses is to equip students with the skills necessary to succeed in the real world of work.
Consequently, professional training plays a role in creating people's personalities. It is possible to
develop personalities through engaging in mental and physical demanding tasks. Additionally,
industrial training may increase students' awareness, enabling them to develop their
communication skills.

Additionally, in an effort to advance both the business and their own personal growth, students
can learn how to engage or communicate with each employee of the company as well as its
clients. Students can adjust to the workplace culture and environment throughout the company
with the help of this industry training. Furthermore, it is known to us how each employee behaves
and works, both positively and negatively, to carry out and finish a task that has been assigned to
them.

Furthermore, industrial training trains students in work ethics and conventions. This is because
each employee must adhere to all company policies to produce perfect job results. Maintaining
the company's reputation and preventing harm are both possible by following by its ethical
standards.

Thus, specific to an industry training can also indirectly help students develop and transform their
personalities and self-images into highly competent, self-assured individuals who can support
society in raising community awareness, capabilities, and living standards.

TECHNICAL REPORT

3.1 Safety

Safety is the condition of being protected against physical, social, spiritual, financial, political,

emotional, occupational, psychological, educational or othertypes or consequences of failure,

damage, error, accidents, harm or any other event which could be considered non-desirable.

Safety can also be defined to be the control or recognized hazards to achieve an acceptable

level of risk.

3.1.1 Workplace Safety

A safe work environment is a productive one. No matter the size or type of the business,

procedures for safety in the workplace are a necessity for all staff. Safety measures protect

employees as well as equipment and business property. Avoiding or minimizing injuries and

damage to equipment and facilities will result in fewer expenses and more profit for a

business.

Each business should have a safety policy in place, created either by management or in a

joint effort between management and staff. Every employee has a role in carrying out the

safety policies. A safety handbook should be created identifying safety issues and spelling

out consequences of not following the appropriate safety procedures.

32
3.1.2 Hazard Identification

At first glance, the semiconductor industry looks sterile. Between the clean rooms and

personal protective equipment (PPE) such as gloves, gowns and respirators, conditions at chip-

making plants have been described as cleaner than the average hospital. On important notes,

electrostatic discharge can be extremely hazardous when working with semiconductors and

related components. Common work safety concerns can include ergonomics, presence of

hazardous chemicals, mechanical problems, noise pollution, restricted visibility, dangers of

falling and weather-related hazards. Issues with non-ergonomic equipment may cause human

health problems, including sore backs and carpal tunnel syndrome. Chemicals can explode,

causing burns, or pose the danger of poisoning.

Mechanical safety issues can occur related to the operation of any machinein the workplace.

Noise and visibility issues can compromise an employee’s hearing and sight. Falls resulting

from poor housekeeping or negligence can cause serious injury and death; procedures should

be in place to prevent them.

3.1.3 Hazard Preventation and Control

For electrostatic discharge problem, Amkor Technology Malaysia has practice several

precautions to eliminate it. Firstly, all production lines at Amkor Technology Malaysia are

ESD-Safe and Cleanroom Environment. A cleanroom is a working environment where

concentration of airborne particles and contaminationis controlled to maintain the specified

limits.

Figure 3.1: Air Shower Before Enter Cleanroom

33
 Secondly, ATM require all the staff to wear ESD-Safe wear before entering the production

line to eliminate electrostatic discharge which can cause damage or defects to electronic

products.

NO. ESD-SAFE WEAR DESCRIPTION

1 Smock / Jumpsuit main reason people wear ESD
smocks or jumpsuits is to
shield their insulative clothing
and minimize the electric
fields generated from their
clothing.
-ESD clothing fabric is an
isolated charged insulator
which cannot be grounded and
the resulting charges can
threaten ESD control.
st smocks/jumpsuits are
constructed of a dissipative
material which incorporates
texturized polyester and carbon
nylon fibres.

34
 Shoes o prevents a build-up of static
electrical charges in the human
body by sending these charges
to the ground in a very safe and
controlled manner also prevent
the sudden flow of electricity
between electrically charged
objects
caused by contact.

3 Gloves o minimize the amount of static

electricity in a particular work
environment, such as when
handling sensitive electronics

Table 5: ESD-Safe Wear

Thirdly, to eliminate electrostatic discharge that can damage product, ATM also use Anti-

Static tools and equipment, lay ESD-Safe mat on table or work bench and ground it, use

ionizers (static eliminator) for ionization (charge mitigating) to neutralize the charge where

grounding is not possible and also use antistatic bags forpackaging PCB when transporting or

storage.

3.2 Process Flow at M4XF Production Line
3.2.1 Introduction
M4XF is one of production line at Amkor Technology Malaysia. Every production

line has specific production depends on customers and packages. On M4XF, most

production is for SO8-FL, TSON8-FL, Vishey, Toshiba, PSMC and TOLL packages.

Most of production run at ATM are for discrete device. A discrete device (or discrete

component) is an electronic component with just one circuit element, either passive

(resistor, capacitor, inductor, diode) or active (transistor or vacuum tube), other than

an integrated circuit. The term is used to distinguish the component from integrated

circuits and hybrid circuits, which are built from several circuit elements in one

package. It typically refers to semiconductor devices.

To produce a complete device, there’s several process that need to go through.

The process is divided into three parts which is Front of Line, Middle of Line and End

of Line.

Figure 3.2: Process Flow a M4XF Production Line

37
3.2.2 PDA Machine (Canon BESTEM – D310/510)
During my industrial training, I was assigned to work at M4XF production line.

To be specific, I was placed on front of line (FOL) section. FOL process consist 6

process which is wafer mount, wafer saw, die attach, vaccum reflow, flux cleaning

and wire bond.

On M4XF, PDA is a machine that do a process of attaching the pellet to the

frame by means of soldering/ Ag paste/ pellet/ clip. This process needs to be done

before move to wire bond process. In PDA there are using combination of four unit

of machine which is 2 unit of die bonder machine, 1 unit of clip bonder machine and

1 unit of reflow machine. Every machine has different task. For die bonder, this

machine needs to attach the die on the frame. Why the PDA need to use 2 unit of die

bonder machine because the die bonder needs to catch up with the clip bonder speed.

Clip bonder task is to attach the clip on the die. Reflow machine task is to heat the

lead frame to melt the solder paste. The solder paste will melt if expose to high

temperature, when the solder paste melted the solder paste will hold the clip and pellet

to the lead frame. Material use in this process are wafer (real shape of pellet before

sawing process), ag paste or solder paste, clip and lead frame.

Figure 3.3: PDA process machine

38
 3.2.3 Canon BESTEM – D310/510 Process Flow

At the die bonder 1, the machine is have doing only for the odd process which is when attach

the solder and pallet to the frame. At die bonder 2, the machine only doing for even which is

when attach the solder and pallet at the frame only do for even, but this 2 die bonder can be

setting if want to use 1 die bonder only for process “ clear lot “. This process is for the last

wafer that we need to used. This process will happen when last lot for the production.

At the clip bonder the machine is attach the solder again and insert the clip to cover the

pallet.The bonding head can cut the clip and attach to 14 pallet at one time, at the right of the

machine we have the slot for insert the clip, there to so many types of clip. After done for clip

bonder process, the product will go to machine BCOS VI, the function is to heating the solder

and make the solder will attach properly to frame and pallet.

During my industrial training period, there are several activities that I have

done related to Canon BESTEM. Here are the few activities that I have done:

NO. ACTIVITIES NOTES

1 Cleaning dispense nozzle

What : Too many alarm paste NG too less
occur
Why : Because the nozzle was soak and
didn’t come out the solder as well
When : When to mount solder on the frame
and pad
Where : At nozzle and dispenser kit
How :
1. Need to take out the nozzle kit from solder
2. Take out every each dispenser kit with
nozzle
3. Blow the solder paste at nozzle and
dispenser kit with air gun
4. Enter the nozzle into an ultrasonic
containing methanol acid
5. Wait until 10 minute and take out the
nozzle and dispenser kits and blow with air
gun
6. Reinstall nozzle to dispenser kit and
solder
7. Do discharge plate to confirm the nozzle
is good condition

40
2 Change solder paste
What : Need change new solder when solder
already reach their limit
Why : Every solder have the limit to prevent
oil in solder through the nozzle and course
nozzle logged
Where : Solder paste and nozzle
How :
1. Bring solder to discharge plate to remove
solder more easily
2. Loose the screw and take out the solder
carefully
3. Remove the nozzle and pressure host and
change with new solder paste
4. Then install back nozzle and pressurehost
5. After that, do piercing on discharge plate
to stabilize the solder paste
6. Lastly do ‘auto teaching discharge Z’
and auto teaching multi point’ on dummy
frame

3 Change rubber tip

What : Changing rubber tick to perform pick
up pallet
Why : After using the same rubber tip for a
long time, it will affect the rubber tip unable
to pick up the pallet
Where : At the feeder
When : To pick up pallet to bond
How :
1. Change new rubber tick. However the
position and size must be correct because
pallet has to many type and size, the size of
the rubber must match the size of the pallet

41
4 Solve problem sensor cant
What : The pick up frame cant detect which
detect
one is paper or frame cooper
Why : The pick up was unable to identify the
copper frame and had thrown the frame into
a paper container
Where : Pick up from load frame to work
mechanism
When : During pick up from load frame to
work mechanism
How :
1. This problem occur because both sensor
do not touch frame, and sensor triggered
frame is a paper
2. When the position of the sensor is away
from the vacuum, the sensor cannot touch
because the frame is bent
3. Close the position of both sensors with a
vacuum

A test program was developed to evaluate the effectiveness of vacuum reflow processing on

solder joint voiding and subsequent thermal cycling performance. Area array package test

vehicles were assembled using conventional reflow processing and a solder paste that

generated substantial void content in the solder joints. Half of the population of test vehicles then

were re-processed (reflowed) using vacuum reflow. Transmission x-ray inspection showed a

significant reduction in solder voiding after vacuum processing. The solder attachment reliability

of the conventional and vacuum reflowed test vehicles was characterized and compared using

two different accelerated thermal cycling profiles. The thermal cycling results are discussed in

terms of the general impact of voiding on solder thermal fatigue reliability, results from the open

literature, and the evolving industry standards for solder voiding. Recommendations are made

for further work based on other void reduction methods andadditional reliability studies.

The vacuum reflow profile for the re-assembly process is shown in Figure 4.19. The red

rectangle denotes the total time the substrates were in the vacuum chamber, which is

approximately 60 seconds. This total time includes transport of the test vehicles in and out of

the vacuum chamber as well as pump down, refill and dwell times. The pump down time is 8

seconds, the dwell time at 10 torr vacuum is 20 seconds, and the refill time is approximately 5

seconds. The peak temperature in the reflow profile is achieved while the substrates are in the

vacuum chamber under IR Panel heating.

 CHAPTER 4

CONCLUSION AND RECOMMENDATION

4.1 Conclusion
Industrial Training is program that expose student to the real working environment and
experience. Through Industrial training, I can conclude that industrial training is very important
and it can give many advantage for student whowill graduate their Diploma or Certificate to gain
experience before they get to the real situation in the future where the student being expose to
many kinds of job or work with the time given.

In duration of 20 weeks of industrial training in Amkor Technology Malaysia, I have learn a lot of
things which cannot be learn in Polytechnic. In term oftheory, trainee realized that not all the theory
part is the basic for us to know more knowledge but hands- on experience is important as well. In
real world there have plenty of unforeseen factors can be occurred. As what trainee studied in
Polytechnic,most of the theories are for ideal case, but when come to a real world, it needs to
modify and compensate with certain factors so that the results get are closet to the ideal.

Besides, my communication skills are strengthening as well when communicating with others.
During my training period, I have received criticism and advice from engineers and technician
when mistakes were made. However, those advices are useful guidance for me to change myself
and avoid myself making the same mistakes again. Apart from that, I had also developed my
engineering skills through various activities that I had done. In sum, the activities that I had learned
during industrial training really are useful for me in future to face challenges in a working
environment.

Throughout the industrial training, I found that several things are important and one of them is
relentless punctuality. Be willing to get to the office early, never be in a hurry to leave office early
and complete tasks by their deadlines. When it feels like you have a million things to do, make a
list of everything based on the deadline and how important they are. This will help you break down
your work, andhow much time you should spend on each task.

50
 Besides that, as an industrial trainee, asking a good question is very important to gain

knowledge. Think in advance of questions to ask. If you are meeting with a senior colleagues

or supervisor, think of thoughtful questions you canask to demonstrate you’ve prepared for

the meeting and respect her time. Students also need to know not ask too many questions

because that will show you didn’t even try to look for the answer yourself.

Teamwork is one of the important key as well. Trainee got a chance to work as a team with

other people. As what mentioned before, teamwork is very important because it can determine

the successful of given tasks. In real world, it is impossiblefor us to work alone. People might

need others helps in order to complete the tasks. During these 20 weeks, I work with my

supervisor. While doing a task, a lot of communications needed between us.

Although the challenges faced by each student during the Industrial Training differ from

each other, what is important is that the individual must be morepositive in dealing with each

situation so that the experience gained can be utilized and stimulated in the future.

In conclusion, the industrial training program is very good and can createthe potential

for students to be better in the field they want to work in the present. During the training. It is

clear that the training objectives have been achieved over the last weeks while they are being

implemented. Therefore, it can be concluded that all the disclosures given to the trainees

during this training are very useful and will be useful in the future.

51
4.2 Recommendation

Comments and suggestions are the freedom given to every student to make any

suggestions, opinions and comments on any problems and other matters pertaining to

their industry training. This is because every suggestion and recommendation will be

taken into account and addressed to improve the trainingprogram in the future. Each and

every proposal suggested is a good input for the actions of the parties involved. Each of

the comments and suggestions provided is intended to provide new ideas for mutual

development. It is not at all for the purpose of humiliating anyone involved during industrial

training.

4.2.1 Students

A good preparation must be made by student their self who will undergo industrial

training before they step out from campus. The preparation is not only on the equipment

or stationary but mentally and physically is also very important so that students are ready

to enter the working zone, the changing of environment around them. This is a must for

student so that this situation will not affect student mentally making them easily to give up

during the training.

Students also need to choose the most preferable company when making decision.

Before industrial training, student need to make some research about the company that

caught their interest. They can’t just choose a certain based on one aspect. Students

need to consider overall aspects before making decision.

52
 4.2.2 Polytechnic

There are also a few matters that need to be improved by the Polytechnicand one

of the improvement that can be suggested is implementing the usage of English

Language during lecture in class. The usage of English language is very important when

working in the field that revolved around development because most of the business

deals were carried out using English language. Most of the Polytechnic students are

unskilled in speaking in English. For example, business meetings were usually carried

out by using English language. So, for student that less skilled in that particular language,

the matter of discussions in the meetings willnot be understood by the students. This will

affect the students learning experience.I hope that the management of the Polytechnic

will stress more on the English language usage among students.

The managements of Polytechnic especially UPLI (Unit Perhubungan Dan Latihan

Industri) should hold more visits to the company where trainees who were undergoing the

industrial training as often as 2 or 3 times along the 20 weeks of training to monitor their

development and to ensure that students are always on the watch and monitored at all

time. This is because students tend to procrastinate knowing that there’s no observation

will happen the near future and do their work last minute.

53
 4.2.3 Organization

There are also a few matters that need to be improved by the company which is Amkor

Technology and one of the improvement that can be suggested is the company need

understand students more. What does it mean by understand students more is that the

firm should not give the student any work that they do not know without giving any

guidance on how to do the work correctly and leave the students to figure it out by him or

herself. This is because sometimes, the work that had been given was yet to be learned

by the students, so, they need some guidance first before they can start working on the

task that were given to them.

Besides that, I think the industrial trainees need to have technicians as supervisor. This

is because engineer usually had a tight schedule and also a tons of reports to be done.

They might don’t have time to give proper lesson to trainees. Aside from that, technicians

are more exposed to technical problem directly at the machine. With that, trainees can

learn something new more frequently. If trainees had technician as their supervisor, they’ll

learn more deeply about something that related with their job scope.
