Week 1 (19/7/2020 - 25/7/2020)

21/7/2020 (Tuesday)

Working time: 8:30am – 6:00pm

• As soon as I arrived at Plant 21, I met the HR Officer in charged which is Mr Zafryl Zaheidy.
• There were 8 of us gathered by Mr Zafryl and I am the only girl trainee.
• He helped us create our fingerprint scan.
• The first day of internship required me to fill in a few forms and hand out the documents asked from the HR Officer via email.
• First day is the Orientation Day which we were asked to gather in the meeting room at Plant 21 and wait for our instructor to walk in and give us a few briefings.
• There were 4 briefings from Security, OSHE, Protocol and Human Resource respectively.
• After lunch, we were given our own batch completed with our employee number and a bar code.
• Before the day ended, Mr Zafryl gave out the particulars of the specific department we have to be in throughout the internship period.
• I was assigned to go to P13 under MCOB and SMT Department

22/7/2020 (Wednesday)

Working time: 8:30am – 6:00pm

• As I arrived at P13, Cik Tiara who is the HR Officer in charged directed us to follow her and she helped us to create our fingerprint scan at P13.
• She gave us our own PPE including jumpsuits, ESD shoe and locker key.
• After storing our own personal stuffs in the locker, we went to Level 3 to meet my supervisor, Mr Tang Kheng Leong wearing ESD shoe.
  • We are required to wear ESD Shoe inside the Clean Room or any department that handles unit.
• Mr KL Tang directed me to an engineer name Cik Nurul Ida Syaheera.
  • Kak Ida will be assisting me under Mr KL Tang’s supervision throughout my internship period.
• First, Kak Ida showed me around the SMT and MCOB Department.
  • There are two separated rooms from this department.

• Later, I was taught to use the OGP Machine to measure the fiducial distance on the PCB (Printed Circuit Board) in the SMT Department.
  • OGP Machine (3D Multisensor Measurement Mind) is a special machine that uses sensors and microscope that measures distance precisely.
  • There are many type of PCB produced by Inari but I was assigned to measure 10 PCB Strips only (5 Carneros and 5 Nightwing).
  • There are two types of PCB Strips (A and I strips).
  • Each type has 3 groups which are A-, A, A+, I-, I and I+ respectively. These groups enable us to determine the most accurate stencil to be used later. This process is called grouping.
  • These strips are measured after exposed to the surrounding (data taken with an interval of 1 hour) to observe their distance difference to analyse the behaviour of the PCB.
  • Graph is plot for further analysis.
• After lunch break, I was asked to measure 30 PCB which is labelled as A- by the supplier.
  • After measuring the distance, the actual grouping for this panel is A.
  • This panel is measured every 3 hours to observe the distance difference.
  • Graph is plot for further analysis.

23/7/2020 (Thursday)

Working time: 8:30am – 6:00pm

• After clocking in, I continue to measure the 10 PCB Strips while waiting for Kak Ida to come.
• Around 10:00am, we went to another SMT and MCOB Department which is located opposite to my current department.
  • Since Kak Ida has her own work to do, I was asked to self-explore the department to gain more knowledge.
  • First, I went to the machine labeled FAVI which they used to inspect the defect and on the unit. The operator in charge of FAVI #4 explained to me how the machine works.
  • Next, I went to the machine that carries out separating process. The operator in charged is an Indonesian woman name Kiki. Kiki taught me how the process works to separate the units from the sticky plastic called mylar. According to Kiki, there are many devices needed to be separated daily which includes Nightwing, Coucou, Carneros, Bates, Desmond and Sinuri.
• After lunch break, I went to the OGP Machine to measure more set of data for the 10 PCB Strips.
• Then, Kak Ida came and we went to the second SMT Department for my new task.
  • I was given a panel with a lot of units on it and asked to count the unit manually.
  • Then, Kiki separated the unit and labelled the package as Desmond.
  • Those units are brought to a counter machine to carry out counting process. The machine is an automated machine that uses sensors and vibrators to count the quantity of units.
  • Next, the chips are weighed and counted using the electronic beam.
  • The quantity obtained using these three methods are compared to obtain the accuracy and analysed the percentage error.
• Then, we went to the OGP Machine to measure more set of data for the 10 PCB Strips. Since the graph is observed to be stable, the measuring process is considered complete.
• With the remaining time, Kak Ida taught me to program using the OGP Machine.
  • I learnt to program a few techniques to measure the fiducial distance and the most effective way is the one programed by Kak Ida which requires less than 20 seconds to determine the distance.

24/7/2020 (Friday)

Working time: 8:30am – 6:45pm

• After clocking in, I went to the OGP Machine and try out a few programs while waiting for Kak Ida. As soon as Kak Ida arrived, we went to the store to collect a panel of 30 A-Strips name Nightwing.
• The fiducial distance of this panel is measured at 10:00am (0hrs).
• After that, Kak Ida and I went to the other room to find for machine name FAVI #14. This machine is handled by an engineer name Cik Fatin.
• Mr KL Tang assigned us to capture the mold chip coming out from FAVI #14. Kak Ida taught us to access the data from all FAVI machine.
  • FAVI Machine is used to inspect each unit and separate them into bins according to the unit condition (accepted or defect)
  • For example, there is bin for mold chip defect, scratch defect and many more.
  • Since Mr KL Tang asked us to capture the mold chip defect, we went straight for that.
  • Then, Mr KL Tang came by to make observation. We had some conversation about the company’s problem before Mr KL Tang assigned me for my new task
• For my new task, I went to the separation machine where Kiki is assigned.
  • I was assigned to count the units on 20 panels of different PCB.
  • For each panel, there is a prescription that stated the number of units on each panel.
  • After counting the units, I compared the number of units that I count with the number stated on the prescription and find the percentage error.
• After lunch break at 1:00pm (3hrs), I measured the Nightwing panel and record the data.
• Then, I went to the separation machine to continue counting the remaining panel until finish 20 panels.
  • From this process, I realise that each unit for different device has different measurement and different size.
• At 4:00pm (6hrs), I measured the Nightwing panel and record the data.
• I have to measure the panel for the 7hrs at 5:00pm but another internship trainee was using the OGP Machine. Therefore, Kak Ida asked me to return the panel to the store.
• At around 5:50pm, Mr KL Tang came by and assigned Kak Ida and I to measure the width and length of the
  • This instruction was given by Mr Sabran which is the COO of Inari. Therefore, this needed to be done immediately.
