These are the high frequency PCB design tips for PCB interconnect. If you are familiar with these methods, you will understand that the coplanar microstrip design with copper cladding on the back is more economical and practical than the strip design.
the main problem of the interconnection between chip and PCB is that the high interconnection density will lead to the basic structure of PCB material becoming a factor limiting the increase of interconnection density. This article shares practical tips f
Not only in the PCB board copy process, is in the circuit maintenance, often need to remove the integrated circuit from the printed circuit board, and because the IC pins are more and more dense, it is difficult to disassemble, sometimes will damage the i
PCB copying board from reverse research to break foreign technology monopoly and control, and core technology digestion and absorption and re-innovation, or can improve the level of core technology localization.
For some basic electronic circuit framework and schematic method, engineers need to master, not only to be able to draw some simple and classic basic cell circuit composition form directly, but also to form the overall framework of electronic circuit.
At present, electronic and digital products, automobiles, medical products and other products such as circuit board production requirements for the process and speed is relatively strict
In low-frequency circuits, where the signal frequency is less than 1MHz, the inductance between the wiring and components can be ignored, and the voltage drop generated on the resistance of the ground circuit has a great impact on the circuit, so the sing
The thickness of PCB board should be determined according to the function of PCB board, the weight of the mounting components, the specifications of PCB board socket, the outline size of PCB board and the mechanical load to be borne.
In order to suppress the cross talk between the printed circuit board wires, in the design of wiring should be as far as possible to avoid long distance equal wiring, as far as possible to open the distance between lines, signal lines and ground and power
In general, the direction of wave soldering on the printed circuit board should be parallel to the long side of the printed circuit board and perpendicular to the short side of the printed circuit board.
The two long edges of PCB should be parallel, and the non-parallel edges should be added to facilitate the equipment transmission in the production and processing process.
Now the installation is mechanized, the hole position of the circuit board and the deformation error of the circuit and the design should be within the allowable range.
