The integrated circuit design field is facing a severe reality. Only about 20% of ASIC chips succeed on their first tape-out. A significant reason for the high failure rate is that the challenges brought by new process nodes have not been fully understood. While some long-standing issues have been integrated into design tools and processes, … Read more
Case IntroductionPCBA for Agricultural DronesFunction Overview1. Flight Control and Navigation Flight Controller: As the “brain” of the drone, the flight controller integrates a microcontroller unit (MCU) that processes signals from sensors and executes flight tasks such as takeoff, hovering, route planning, and landing. Inertial Measurement Unit (IMU): Includes accelerometers, gyroscopes, and magnetometers to monitor the … Read more
Recently, I analyzed Yushu Technology’s L1 LiDAR: “Snow Ridge · Disassembly and Principle Analysis of Yushu Technology’s L1 LiDAR“. Among them, the chips on the circuit board lack silkscreen printing, making it difficult to understand their specific functions. Therefore, I asked experts from the chip company to perform a decap on the main chips to … Read more
