For traces with a certain width, three main factors will affect the impedance of PCB traces. First of all, the EMI (electromagnetic interference) of the near field of the PCB trace is proportional to the height of the trace from the reference plane. The lower the height, the smaller the radiation. Secondly, the crosstalk will change significantly with the height of the trace. If the height is reduced by half, the crosstalk will be reduced to nearly a quarter.

A printed circuit board (PCB) is used to carry electronic components and provide a master circuit for connecting the components to the circuit. From the structural point of view, PCB is divided into single panel, double panel and multilayer board. But most people can't tell the difference, so what are the three differences?

The environment in an industrial workshop is different from that of ordinary places, especially in production and processing workshops. Summer temperatures are already high, and combined with the heat dissipation from the machines, temperatures in the workshop often reach over 60°C, and in some cases even reach 80°C. The HDI PCB in industrial control equipment are the "brains" of the equipment. If they are not heat-resistant enough, problems can easily arise. These include circuit aging, component loss, and even direct short circuits. If the equipment stops, the entire production line will be affected.

The covering film of FPC circuit board shall be processed by opening the window, but it cannot be processed immediately after being taken out from the cold storage. Especially when the ambient temperature is high and the temperature difference is large, water droplets will condense on the surface.

Semiconductor products cover everything from basic diodes and transistors to complex integrated circuits and microprocessors. These products play a crucial role in electronic devices, including transistors for amplifying and switching current, diodes for rectifying and stabilizing voltage, and memory devices such as DRAM and flash memory for storing and processing data. Integrated circuits,

1. Introduction to chips What is a chip? A chip is an integrated circuit that can be compared to the brain of an electronic device. The components on a chip can perform various tasks, such as processing information, storing data, performing calculations, and controlling operations. Why is it called a chip? "Core" represents the core and center, and "chip" represents a thin piece or fragment. A chip is a thin piece made of semiconductor materials, which, as the core part of the entire circuit system, integrates key circuit structures.
