Because, if you select higher voltage and threshold, increase the number of high voltage leakage reading, you can improve the detection rate of PCB defect board. For example, a large Taiwan-funded PCB enterprise in Suzhou uses 300V, 30M and 20 euros to te
The PCB designer can automatically change the relevant constraints by simply updating the process characteristic parameters. The PCB designer can then run the DRC(PCB Design Rule Check) to determine if the new process violates any other PCB design rules a
dielectric layer material. The material of dielectric layer has influence on the hole filling. Compared with glass fiber reinforced materials, non-glass reinforced materials are easier to fill holes.
Starting from the most basic PCB board, this paper discusses the function and design skills of PCB stacking in controlling EMI radiation.
The capacity of filling holes is greatly affected by the ratio of hole thickness to diameter. Relatively speaking, PCB systems are used more in business.
The output value of the global electroplating PCB industry accounts for the proportion of the total output value of the electronic components industry growing rapidly.
The first is the preferred solution. The outer layer of the PCB is all the strata, and the middle two layers are the signal/power layer. The power supply at the signal layer is routed with a wide wire, which allows the path impedance of the power supply c
At present, PCB board manufacturers generally adjust PCB prices according to different payment methods, with a range of 5%-10%, which also causes the difference in price.
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
Flux spraying The PCB is carried by the X/Y manipulator through the flux nozzle, and the flux is sprayed on the PCB to be welded. Flux has a single nozzle spray, microporous spray, synchronous multi - point/graphic spray.
only light gas precipitation. Generally, the PH value of PCB nickel plating electrolyte is maintained between 3 and 4. The nickel plating solution with higher PH value has higher dispersion force and higher cathode current efficiency.
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.
