Problem-solving and decision-making hardware engineer with 9-years experience of AR glasses/All-in-one PC/ Notebook Computer product. Technical SkillsSchematic design:- To design the entire system circuits, including Intel/AMD/Qualcomm core logic, I/O components, MCU, Gigabit LAN IC, Audio Codec, Sensor IC, Bridge IC, Repeater IC, USB Power Delivery, USB3/DP MUX CC controller, ESD, EMI, and PMIC. - To design the definitions of GPIOs, I2C/SPI configuration, power sequence, power delivery structure, and clock configuration. PCB Layout:- To make decisions on PCB layers, placement, routing, and impedance controlled. - To confirm the trace width, trace spacing, reference plan, differential length matching, power plan width, quantities of power via to meet the specifications. Measurement and Test:- High speed signal integrity measurement (USB/HDMI/DP/PCIE/SATA/MIPI) - Leakage current measurement when system into Suspend/Hibernation/Power off mode. - Power consumption measurement. - Power sequence and power quality measurement. - Timing measurement (Rise time/fall time/setup time/hold time). - System stability test (3DMark/Stress test). - HP SQTM and SVTP reports.- Power Load test for ChromebookTroubleshooting ability:- To accurate issues, for example, signal do not output, system do not boot up, functions have been lost, screen do not display, and voltage has dropped.- To make a strategic decision of short-term solution and long-term solution. Mass production:- Fixture design for mass production test. - Factory mass production procedure experience.
