Ground Noise Isolation and Reduction Solutions for High-Precision ADC Circuit PCBs

Ground Noise Isolation and Reduction Solutions for High-Precision ADC Circuit PCBsHigh-precision analog-to-digital converters (ADCs) are widely used in industrial measurement, medical devices, and high-precision instruments. However, in actual circuit design, the performance of ADCs is often affected by PCB layout and ground noise, leading to signal distortion, reduced resolution, and even data errors. Therefore, reasonable … Read more

Understanding Various Buses: A Comprehensive Guide to SPI, I2C, UART, I2S, GPIO, CAN, and SDIO

Buses, buses, they always get you tangled up. In this world, signals may be the same, but there are thousands of buses, which can be quite a headache. In general, there are three types of buses: internal buses, system buses, and external buses. Internal buses are used for interconnections between peripheral chips and processors within … Read more

SPI, AOI, and X-Ray: The Triple Guardians of SMT Production

In the SMT (Surface Mount Technology) production line, the birth of each circuit board is a game of precision and efficiency. From solder paste printing to component placement, and then to soldering and curing, even the slightest flaw in any link can trigger a “butterfly effect”—leading to unstable product performance at best, or mass rework … Read more
