Enviromental Stress Screening
Vibration testing
Decompression test
Thermal Cycle
Vibration testing is to ensure and simulate that the display lighting module is able to withstand vibration generated by plane during take off ,flight or landing .
Vibration Testing
Decompression Test
Decompression test is to simulate aircraft compression on LCD Assembly module (LAM) in high altitude
Make sure that the LAM can remain functional after being depressurized
Thermal Cycle

Thermal cycle is to expose the hidden defects that were introduced during the manufacturing process and to verify that the products are robust enough to meet the required condition

Ensuring Smooth Production Flow

BLU Assembly is to combine both LED Circuit Board, Aluminum metal base and Reflector together. After combining all of them, it will become a unit before going to the next process BLU ATP.
BLU ATP or LED Integrity Check is important because during this process, it helps by checking if the LED lights are working fine before combining is together.

Checking the blue, red and green LED stable and sustainable without blinking. In any case of the LED Light producing problems (abnormal) or can’t produce white light. Stop, Ask & Wait for help assistance.
DMB ATP is to check the DMB board with a given Voltage input into the device that is it working perfectly or fail the test before mounting the BLU and DMB with the LCD product together.

During the attachment I did Cable making, Label printing, Assembly of metal cases, Making of connectors, crimping, Laser marking, Packaging and failure analysis.

Cable Making
I also Assist in…
Develop new checkers for production use.
Ensure checkers component and equipment are sent for calibration
Programming new equipment
Making improvement to screening oven
Label Printing
Visual inspection
Making of Connecters
Laser marking
DMB ATP or DMB Integrity Check is to check the PCB with a given Voltage allowance input to the device that will be working perfectly. Any Failed tests are not be mounted with the BLU and with the LCD product together.
There are
3 important steps
before combining BLU & DMB together
Provide functional check on the Printed Circuit Board (PCB) to ensure the PCB working perfectly before mounting them into the final product.
BLU Workstation
The purpose of Visual Inspection

Identify any defects or flaws from the overall product

No damage is done to the product during all of the previous test procedures

Applying protective film to the finished product

Packaging of product with ESD protected plastic

Lastly, Acceptance test record is a procedure where all the information of the particular product are recorded into excel

We’re from New Product Innovation department under the maintenance group, our objective is to support the production by doing repairs and servicing for machine and tools.

New Product Innovation

Flux Machine

Wave solder Machine

This machine comprises a flux machine and wave solder machine.

Operational test:

1) There’s a list for us to check on the gauges whether is in range of requirement.

2) Checking of solder height, if is too low we need to fill it in with solder bar.

3) Checking whether the solder wave touches the test board.

Future Attachment Students
Dimming Board Testing
Self discipline
Ask when in doubt
In conclusion, We would like to thank ITE for giving us this opportunity to work at Yokogawa Electric Asia, which helps us to gain experience and prepare for our future workforce life.
Always have a positive learning attitude
Language Courses
Resources must be sufficient for a smooth production

For your Kind Attention
Final Process
Flux Machine- To spray a controlled amount of flux on the printed circuit board before going into the electrovert to prevent oxidation of the base and filler material.

Electrovert – Used to solder small surface mount technology (SMT) parts onto the Printed circuit board.

Given the chance to operate machines
Build interpersonal skills
Good relationship
