the Tg value will decrease after baking PCB is also a problem. A better method is to control the water absorption conditions from the selection of PCB board and the manufacturing process.
From the two formulas discussed above, it can be concluded that the use of thinner PCB board is beneficial to reduce the two parasitic parameters through the hole.
They can be integrated on a small circuit board, used in wireless digital audio, digital video data transmission system, wireless remote control and telemetry system, wireless data acquisition system, wireless network and wireless security system and many
Many companies have started to set up a circuit board pricing program on their Web sites, with rules that allow customers to freely calculate prices. People who do not understand PCB can also easily calculate the price of PCB.
For the new PCB board we just got back, we should first observe roughly whether there are any problems on the board, such as whether there are obvious cracks, short circuit, open circuit and other phenomena.
Odd layer PCB needs to add non - standard laminated core layer bonding technology on the basis of nuclear structure technology. Compared with the nuclear structure, the production efficiency of the plant adding foil outside the nuclear structure will decr
The above is the overview of optical module PCB and optical device simulation. There are not many things to simulate, but there are also many places to be carefully handled.
The above is the knowledge that optical module PCB and optical device cascade simulation need to master. Compared with chip packaging and board level PCB, there are a lot less things, and because there are a lot of repetitive things in optical module simu
This paper first introduces what is impedance and impedance type, then introduces the PCB circuit board why to do impedance, describes the significance of impedance for PCB circuit board, the specific follow Xiaobian together to understand.
Electrolysis of copper foil is also used in situations where the carrying capacity of the current can be increased by increasing the weight of copper to achieve a copper width, such as planar inductors.
On the most basic PCB, the parts are concentrated on one side and the wires on the other. Because wires appear on only one side, this type of PCB is called Single-sided.
The medical field is one of the most sensitive applications requiring PCBS because it requires precision, reliability, and high quality components. For this reason, medical PCBS are specifically designed to suit specific environments, laboratories, and te
