pcb circuit boards from single development to double sided, multilayer and flexible board , along with the development of society continues to accelerate , pcb circuit boards are like a high reliability direction.
With shrinking pcb board volume , reduce costs, improve performance, making printed circuit boards in the future development of electronic products , and still maintain a strong vitality.
Next printed circuit board manufacturing technology trends in performance to a high density , high precision, fine pore size , the fine wire , small pitch , high reliability, multilayer , high-speed , lightweight, thin direction.
PCB circuit board in order to suppress crosstalk between the wires in the wiring should be designed to avoid long-distance equal traces distance as possible between the lines , the signal line and the ground and power lines do not cross as much as possible . Some very sensitive to interference between the signal line to ground a printed line, the crosstalk can be effectively suppressed .
Electromagnetic compatibility is an electronic device is still able to coordinate the various electromagnetic environments , the ability to work effectively . The purpose is to make electronic devices can inhibit a variety of outside interference , the electronic device can work in a specific electromagnetic environment , while reducing the electronic device itself electromagnetic interference with other electronic devices.
