Project : Reduction of VDD3_ACC_DIG Failure Rate DMAIC - Story Board.

[Audio] This phase entails precisely describing the problem or opportunity for improvement, establishing project objectives, and understanding customer requirements..

[Audio] Terminal Pins VDD3 and VDD3_DIG are two independent voltage regulators that are used to supply the digital and analog blocks with 3.3V.This refers to the voltage level present at the VDD3 pin and is crucial for proper trimming of the device. An external capacitor is required to ensure stability of each regulator.During final testing, the voltage regulators were trimmed to 3.3 Volts to supply voltage VDD3 pins while maintaining a constant voltage..

[Audio] Business Case On the year 2023 It demonstrates that the VDD3_ACC_DIG regularly ranks as one of the top failing parameter in 50424-Brocap, resulting in a 4.10% yield loss on the first pass test. Which result to 21,000 Euros revenue lost For the year 2024 The projected is volume for the whole year for 50424-Brocap device is 4,971,436 units This project aims to reduced the failure rate from 4.10% or 204k units to 2.0% or 99k units that will result to 12k euros savings . This initiative is both a strategic imperative for our company and a chance to strengthen our market position, as it aims to increase production output while enhancing overall final test yield..

[Audio] Bar graph shows the failure rate of all the lots that run on the year 2023 averaging 4.10% failure rate..

[Audio] Line chart shows that the monthly Final Test yield for 2023 does not met the target FTY for production on 50424-Brocap. Final Test Yield does not met due to the over rejection on VDD3_ACC_DIG__ averaging 95.5% on the year 2023.
