How to measure the dielectric constant of PCB circuit board material at millimeter wave frequency?
While raw material test methods often introduce uncertainties related to test fixtures or test devices, circuit test methods include uncertainties from test circuit design and fabrication techniques. Because the two methods are different, measurement resu
PCB copper coating should pay attention to those problems? How to choose solid copper and grid copper?
the copper coating on PCB, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line backflow area, reduce the signal external electromagnetic interference.
Destructive analysis of laser coding on PCB materials
Laser marking can be a variety of characters, symbols and patterns, character size can be from millimeter to micron magnitude, which has a special significance for the anti-counterfeiting products.
Maintenance of pcb etching equipment
The formation of residual film slagging indicates that the previous film removal process is not thorough. Poor film removal is often the result of the combination of edge film and electroplating.
Simulation of mixed signal PCB
The shortest and widest printed line permitted by the assembly process shall be used. For high frequency devices, the printed line of the power supply is equivalent to a small inductance, which will worsen the power supply noise and cause undesired coupli
How to improve the thermal reliability of PCB boards
They not only play a conductive role in the design, but also play the role of heat conduction, its thermal conductivity and heat transfer area are relatively large circuit board is an indispensable part of the electronic circuit, its structure is composed
How to deal with PCB sensitive circuit? What are the interference elements?
Compared with the microstrip, the ground coplanar waveguide circuit has the characteristic of low dispersion, and the radiation loss of the ground coplanar waveguide circuit is lower than that of the microstrip circuit when the frequency rises to the mill
Why do photoelectric components on PCBS always fail?
PCB has become the most important and key part of electronic information products. Its quality and reliability level determine the quality and reliability of the whole equipment.
Detailed back drilling process in PCB circuit board production
In China, the demand for backplanes mainly comes from the communications industry, which is now growing in the field of communications equipment manufacturing.
The deformation of the two core plates is respectively
The difference of expansion and shrinkage in the pressing process will be retained through the solidifying process of semi-cured sheet and eventually form the deformation of PCB board.
High Tg products are significantly better than ordinary PCB substrate materials
It has many advanced features, capable of simulating laminar and turbulent flow as well as multi-type analysis, including radiation and convection. Icepak offers a huge library of fans, radiators and materials that provide solutions to everyday electronic
