Developed a schematic for the display module of a water purifier device based on the ABOV MCU, featuring 40 LEDs and 10 touch keys.Designed a single-layer PCB for the main board of the same water purifier product. The PCB outputs 3 voltage levels (5V, 12V, 24V) and incorporates Renesas MCU and 8 sensors.Engineered a cost-effective 2-layer PCB for the display board of a refrigerator, ensuring compliance with the IEC standards (EMC/EMS test : EFT, SURGE, DIP, IMPULSE, ESD). Examined alternative switching ICs (efficiency greater than 80%) for power supplies of home appliances, evaluating price, manufacturing quality, and power capabilities. This reduced the total price of the design.Instructed 2 technical courses for 30 engineers in the R&D department covering topics such as PCB reference layer design, transient voltage immunity and reliability of solid-state devices, HyperLynx, and CST.Extracted necessary PCB component standards for exporting products to other countries.

Verified the stack-up of high-frequency PCBs with up to 12 layers, which included considerations such as layer count, signal-plane layer combinations, symmetric structures, and layer distances.Validated 77 requirements related to EMC, SI, PI on over 100 PCBs using Hyperlynx and CST.Extracted schematic and class 3 PCB design requirements based on IEEE and IPC standards and data presented in Texas Instruments and analog devices application notes.Collected reports, attended meetings, and presented 20 IPC standards in the company’s quality control department. implemented these standards in the PCB design procedures.Authored the book titled ‘Set of Requirements for General Schematic Design’, which comprises 12 chapters. Focused on issues critical for system reliability, stability, testability and manufacturing–often neglected.

Designed a schematic from a reversed-engineered smart home power supply board, analyzing board functionality and performance to facilitate the redesign of the PCB.Devised 2 types of medical beds with automatic toilets. This created a new investment opportunity.BOM listing, ordering and assembly of 2 projects including an ECU system and VR roller coaster.
