[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] The project "Reduction of VDD3_ACC_DIG Failure Rate" of the 50424-Brocap device investigates the low yield issue caused by a high rejection rate of 4.10% or 171K units against target of 2% or 83k units for the entire year of 2023 resulting to loss of 21k euros. This project aims to reduced the failure rate from 204k units to 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.
