1. History of PCB Development The history of PCB development is a chronicle of the continuous miniaturization, integration, and high performance of electronic technology. 1. Concept Origin (Early 20th Century): The idea of “printing” wires on a substrate was first proposed by Germans Albert Hansen and Americans Charles Ducas, laying the theoretical foundation for PCBs. … Read more
MIPI (Mobile Industry Processor Interface) is a standard defined for mobile devices such as smartphones, tablets, laptops, and hybrid devices. Its commonly used physical (PHY) layers are MIPI D-PHY and C-PHY. MIPI D-PHY: It is more commonly used for cameras and displays in smartphones due to its flexibility, high speed, low power consumption, and low … Read more
The biggest challenge in high-speed design is to minimize crosstalk, ensuring good signal integrity during transmission while also reducing the impact of noise on the PCB. Since single-ended signals and Low Voltage Differential Signaling (LVDS) are typical types of high-speed interface signals, it is essential to ensure the transmission of these two types of signals.In … Read more
