Week 6 (23/8/2020 - 29/8/2020)

24/8/2020 (Monday)

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.
• After that, Fitri from the OTSP Team contacted me about the updated TV display.
  • He created new channel for each TV and asked me to try them out.
  • I went to each department to set up the display and captured photos of each content to update him.
  • I noticed that some contents are now properly displayed due to small font size and unsuitable colour used.
  • These problems were updated to Fitri via PowerPoint Presentation slide.
• After lunch break, I help out Kak Nurul with Variance problem.
  • We have to take a few data to be analysed later.
  • For each lot, we tried to obtain the quantity using 3 methods: weighing, manual calculation and machine quantity on lot traveller.
  • For each product, we took 5 random lots to gather the data.
  • By the end of the day, we managed to obtain 15 lots from 5 packages.
  • The data were gathered in Microsoft Office Excell.

25/8/2020 (Tuesday)

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.
• Since the weighing machine has arrived today, we can start our inspection on Variance problem.
  • Ibrahim and I went to FAVI (MCOB B Department) to set the machine up.
• After lunch break, Ibrahim and I studied thoroughly on the machine.
  • First, we learnt on how to handle the machine.
  • Then, we took a few samples to weight out. Thus, since the units are vey small, the machine is given tolerance of 0.03%.
  • To determine if the quantity of the weighing is correct, we need to find out the unit weight of each package first.
  • This task was assigned to Ibrahim and I.

26/8/2020 (Wednesday)

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.
• After that,
• Before going back, I joined a meeting with Mr KL Tang, Mr WL Chang and Mandy.
  • Mandy is an engineer in MCOB Department Specifically at the Lasermark area, and she needed me to help her on measuring some items tomorrow.
  • In this meeting, they are trying to solve the misalignment issue during unit laser-marking.
  • Therefore, I am required to measure the PCB size of each package and compare their sizes with the new jig size.
  • This is to decide on the tolerance of each product to reduce misalignment issue at the laser mark.

27/8/2020 (Thursday)

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.
• After that, I went to Mandy’s desk as requested.
  • She asked me to wait for her at the MCOB Department specifically at the laser mark machines at 10:00am.
  • She gave me a dummy PCB for PEEKABOO to be measured.
  • I went to the OGP Machine and begin writing my own program to measure the requested measurements.
  • The data are collected and I further anaylsed them using Microsoft Excell.
• After lunch break, Mandy asked me to measure another item.
  • This time, she gave a a dummy PCB for SIDURI to be measured.
  • I altered the program I did this morning to suit the measurement for SIDURI.
  • The data are collected and the same technique used for PEEKABOO was applied for SIDURI in terms of data analysis.

28/8/2020 (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.
• After that, Mandy asked me to help her out on another measurement.
  • This time, she asked me to measure SIDURI Jig.
  • I went to OGP Machine and set up a new program to measure the jig.
  • The data collected are then compared with the data gained for the PCB.
  • From this, I can analysed the suitable tolerance needed for SIDURI product.
• After lunch break, Mr KL Tang asked me to help Ibrahim on weighing problem.
  • We observed the current pattern of the unit weight set up by the previous engineers.
  • However, since this issue needed a new routine, Ibrahim and I decided to start from scratch.
  • As for today, we tried to weight out the ESD Plastic bag in every possible way an operator could handle it: with tape on, crumbled plastic, cut-out and stapled.
  • After gathering the data, I key in the data in Microsoft Office Excell.
  • I calculate the average weight for the plastic bag.
  • For further confirmation, Ibrahim and I asked for Mr KL Tang’s help to standardise the way of handling the plastic while weighing the unit.
