the growth rate is the passive components and PCB as the representative of the component plate. 5G substrates, such as soft boards, high-end high-speed materials and PCB, are comprehensively distributed, benefiting from the strong flexibility of 5G and th
The PCB industry will benefit a lot in the industrial chain. With the emergence and rapid progress of 5G communication technology, a number of related fields are entering the situation of technology iteration and product application upgrade simultaneously
As a result, future digital life situations such as remote teaching, intelligent diagnosis and treatment, and AI for industrial risk control have been started in advance.
According to Prismark statistics, mobile terminal PCB demand is mainly HDI and flexible board (HDI board accounts for about 50.68%), and has 26.36% packaging substrate demand.
Each circuit layer in the multilayer circuit board is pressed together by the action of semi-cured sheet; Depending on the circuit design, some areas of the semi-cured sheet need to be cut and then pressed together.
The following is its structure diagram (about circuit symbols and functions will be explained later) :IC design: CMOS devices and their circuits，
At the same time, the direction of the power cord and ground wire is consistent with the direction of data transmission, which helps to enhance the anti-noise capabilit
There is a little bit of short circuiting between digital and analog, but note that there is only one connection point. There are also differences on the PCB, which is determined by the system design.
Ink in the production to protect the role of copper foil, so that the copper skin is not exposed to the outside, will affect the later process, sensitive ink, carbon oil, silver oil, and carbon oil and silver oil have electrical conductivity.
The automotive PCB market is benefiting from the increasing electronization of vehicles as consumers demand more functionality and safety.
The content of PCB incoming material inspection includes PCB size and appearance inspection, PCB warping and distortion detection, PCB weldability test, PCB solder resistance film integrity test, PCB internal defect detection.
Although PCB can be called a high-tech product in the electronics industry, but now the development of PCB is not only challenged by its own cost-effectiveness problems, more is from the challenge of energy conservation and environmental protection.
