These ground plane planes must be connected to the main ground plane through multiple through-holes. It should be noted that the existence of ground point will cause the inductance characteristics of the side to change, so the selection of inductance valu
From parameters to manufacturers, people who do not understand the specific application scenarios of products, and people who know directly study the cost performance ratio.
scanning acoustic microscope shows its special advantage in nondestructive detection of multilayer high density PCB. And the general obvious explosion plate is only through the visual appearance can be detected.
As the carrier of various components and the hub of circuit signal transmission, PCB has become an important and key part of electronic information products. Its quality and reliability level determine the quality and reliability of the whole equipment.
At present, there are more than 100 layers of PCB, then why do people have "PCB multilayer board why are even layers?" What about this question? Relatively speaking, even layer PCB does have more than odd layer PCB.
It should be noted that the simulation design of optical devices to photoelectric conversion (EO\OE), how to accurately reproduce this conversion process in simulation, requires some experience accumulation.
manufacturing technology and system complexity and other key factors have many conflicting requirements, PCB board laminated design is generally considered in various aspects of the key factors after a compromise decision. High - speed digital circuits an
Poor insulation of copper wire will lead to arc between copper wire and copper wire. Too close between the copper trace and the path, it is easy to short-circuit risk; The lack of thickness of the circuit board can lead to bending and breaking.
it is necessary to pay attention to the maintenance order so as to find the shortest path to solve problems, so as to avoid poking and dismantling randomly, which will fail to repair and otherwise lead to greater faults.
If there are a lot of key signals on the PCB to do impedance, you can attach a separate document, will be impedance control line display, and explain the value and error to do, circuit board factory will adjust the control of these "important signal&...
How to consider the welding process in PCB design? 1. Power line and ground wire should meet the following requirements in PCB design: (1) The power line and ground wire of large area should be drawn into a cross section line; (2) The distribution of copp
The following introduces common circuit board analysis methods: 1, AC equivalent circuit analysis method, 2, frequency characteristics analysis method, 3, DC equivalent circuit analysis method, 4, time constant analysis
