Week 3 (2/8/2020 - 8/8/2020)
3/8/2020 (Monday)
Working time: 8:30am – 6:00pm
- Meet Mr KL Tang at his office.
- Update on process changes implementation last week
- Mr KL Tang assigned me to go to MCOB Department B to continue gather data for all FAVI Machines.
- After finished gathering all the data, I went to the separation machine.
- I learnt to separate the units from mylar in details.
- Then, I updated the data on the lot traveller and the book
- After lunch break, I went to meet Mr KL Tang at his office to update my task.
- Then, he explained on the machine converting process at the sawing machine in MCOB Department A.
- This machine converting is to insert new recipe into the list of the recipes in the sawing machine to make them more functional to a wider range of device choices.
- Then, he briefly explained to me the type of machines used in Inari for sawing process and the basic mechanisms of the machine.
- He assigned me to go to the MCOB Department A and meet Mr Hayazi.
- I went to find Mr Hayazi at the MCOB Department.
- Mr Hayazi explained to me thoroughly about the sawing process including its mechanical mechanism.
- He showed me around the layout of the machine.
- According to Mr Hayazi, Inari uses two types of sawing machine which are DISCO and the brand new Accretech.
- For the machine converting process, Mr hayazi have run 3 dummy panels (2 Hanzell and 1 Nightwing) into the machines.
- These dummies were run according to the new recipe created by Mr Hayazi by referring to an actual production panel as guideline.
- While Mr Hayazi was inserting the new recipe, he taught me on how to create new recipe at the sawing machine.
- All of the dummies were approved by the QA Engineers. Thus, the converting machine can be performed completely.
- This approval meant that Nightwing panels can now be run using sawing machine SAW#.60 and #.61 while Hanzell can now be run using sawing machine SAW#.62 and #.63.
- I updated the progress to Mr KL Tang.
4/8/2020 (Tuesday)
Working time: 8:30am – 6:00pm
- I started my day by going to Mr KL Tang’s office to update him more on the conerting machine yesterday.
- Then, Mr KL Tang assigned me to go to SMT Department to find Puan Nor Faqiah and ask her to update the data of AOI Machine for July.
- After that, I went to MCOB Department B to continue gathering data for each FAVI Machine.
- After lunch break, Mr KL Tang asked me to follow Kak Ida to the SMT Department to follow up on the process changes that was implemented last week.
- He wanted the changes to be implemented completely by today.
- However, when we went to the department, we encountered a few problems.
- With the remaining time, I went to sit at the OGP Machine where there was an internship trainee.
- I helped him created a new program to measure the size of the board he was measuring.
5/8/2020 (Wednesday)
Working time: 8:30am – 6:00pm
- Started my day by learning to update on daily yield for SMT and MCOB Department from Kak Nurul using Microsoft Office Excell
- I tried to do the daily yield using some sets of data from the Shop Floor with the guide of Kak Nurul and Kak Ida.
- Since this is my first-time handling this and Mr KL Tang did not assign me with any new task, I really took my time on getting to know the processes to update the yield.
- According to Mr KL Tang, this is going to be my daily task.
- After lunch break, I went to MCOB Department B to gather the data as usual.
- Mr KL Tang assigned me to go to MCOB Department A to measure spv-tape for chimera ring at the laminating machine
- Therefore, I went there with Kak Ida and updated the data.
- Later, Kak Ida and I went to the OGP Machine to measure the warpage for some sample panels.
- This data is required for the implementation of the process changes that will occur in the SMT Department.
- Before going back, I met Mr KL Tang at his office.
- I updated him on the tasks I have done today.
- He asked me to try doing the daily yield for SMT and MCOB Department tomorrow and update them to Kak Nurul.
- He also mentioned the issue with the spv-tape at the laminating machine.
- He said he will be needing me to do some calculation and verification tomorrow regarding this issue.
6/8/2020 (Thursday)
Working time: 8:30am – 6:00pm
- Started my day by updating on the daily yield as per request by Mr KL Tang before 10:00am
- I obtained all the data from the Shop Floor and futher analysed them using the template and the knowledge I have learnt from Kak Nurul and Kak Ida yesterday.
- After that, Mr KL Tang addressed the issue regarding the tape usage in MCOB.
- He gave out 3 scenarios to Kak Ida and I to solve for the cost calculation in terms of engineering economy.
- He listed out the scenarios along with their details such as the width and price per roll.
- After sorting out the important costs, Kak Ida and I analysed the best scenarios to be implemented in the MCOB Department A specifically at the laminating process.
- This is done in order to compare and obtain the best option that is the most economical.
- Then, I presented the comparison to Mr KL Tang.
- After lunch break, I went to do the variance at MCOB Department B.
- I have to manually calculate the units on some random panel to track out the variance.
- All the data were collected and tabulated in Microsoft Office Excell and sent to Kak Nurul.
- Later, I have to go to MCOB Department A to help out Mr KL Tang to obtain the measurement of the metal ring.
- This measurement is related to the spv-tape (mylar) issue
- There were two sizes of metal rings used by Inari.
- I measured both metal rings along with the size of tape consumption per panel.
- Then, I updated the measurement to Mr KL Tang.
7/8/2020 (Friday)
Working time: 8:30am – 6:00pm
- I started my day by updating the daily yield as per request by Mr KL Tang before 10:00am.
- Then, Kak Ida and I went to MCOB Department A.
- Mr KL Tang asked us to simulate the laminating process using both sizes of metal ring if the mylar width is changed to 280mm instead of 230mm (current).
- After gathering all the data, we updated yesterday’s report regarding this matter to Mr KL Tang.
- After lunch break, Mr KL Tang requested us to go to MCOB Department A again to confirm which type of metal ring is used in manual and auto machine respectively.
- Kak Ida and I went to MCOB Department A and checked out all the sawing machines.
- We identified which metal ring is used in auto or manual machine respectively.
- We also identified the specific machine name that runs specific package/lot
- These data are very important to make calculation later on.
- After that, we went back to the office.
- Mr KL Tang asked to analyse the repercussions of changing the spv-tape width from 230mm to 280mm.
- Kak Ida and I did some calculation considering some engineering economy aspects.
- Later, we presented our data and analyses at Mr KL Tang.
