Shenzhen Hongyunlai Electronics is a professional pcb circuit board factory, with advanced production equipment and perfect after-sales service system. Provides more information on pcb pcb design, pcb PCB proofing, single side/multilayer PCB PCB fabricati
Reducing electromagnetic interference is an important part of PCB board design, as long as the design to think more about this side, naturally in the product test such as EMC test will be easier to pass.
SMT in the production process of PCB design requirements,In SMT patch processing technology, there are certain requirements for PCB design. Here, Pate Technology gives you an example.
The design of printed PCB circuit boards starts from determining the size of the board. The size of printed PCB circuit boards is limited by the size of the case shell, so as to fit into the shell.
The increased cost caused by EMC on PCB board is usually caused by increasing the number of layers to enhance shielding effect and increasing ferrite bead and choke to inhibit high frequency harmonic devices. In addition, it is usually necessary to match
Protel is the most convenient to use, the fastest to operate, the best humanized interface auxiliary tool in the circuit aided design (EDA) industry at present, and also the most used EDA tool in China. This paper takes Protel99 SE as a design tool to ana
In the early stage of lead welding, the temperature was not very high, and the original PCB board could be tolerated. Since the temperature was increased after lead-free welding, powder was added to the PCB board to strengthen the PCB's resistance to temp
The same material produced by different pcb manufacturers varies due to its resin content. The dielectric constant decreases with the increase of frequency, so in practical application, the dielectric constant of materials should be determined according t
It has been proved that the reliability of electronic equipment will be adversely affected even if the circuit diagram is designed correctly and the printed circuit board is not designed properly.
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 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 this PCB example, a hot pad has been used -- manually creating arcs and lines, see Pad 1 of J6 for details.
