1. Circuit and Pattern: the circuit serves as a tool for conducting between the original components, and a large copper surface will be designed as the grounding and power layer in the design. The line and the drawing are made at the same time. Dielectric layer (Dielectric) : used to maintain the line and the [...]
1. Ground connection problem? A system is often divided into a number of PCB, power supply, interface, motherboard, etc., the ground wire between the boards is often interconnected, resulting in the formation of a lot of loop, such as 2. Low-frequency loop noise problem? When the signal or power supply between the PCB boards is [...]
If wiring doesn't require an extra layer, why use it? Wouldn't reducing layers make a circuit board thinner? If the circuit board is less than a layer, is not the cost lower? However, in some cases, adding a layer may actually lower the cost. PCB board has two different structures: core structure and foil structure. [...]
Outlook for global PCB industry in 2019 will continue to grow, with 5 g, automotive, networking, artificial intelligence and other new application of booming development, more market opportunities and challenges, including high frequency PCB for the rigid demand, PCB to achieve high frequency is the key to the high frequency copper clad materials (such as [...]
1. How to deal with PCB sensitive circuit (1) the power cord According to the size of printed circuit board current, as far as possible to thicken the power line width, reduce loop resistance. In particular, we should pay attention to the power supply direction in the power line and ground line, which is opposite [...]
South Korean media said that the semiconductor industry in South Korea has begun to deal with China's semiconductor chase, trying to get rid of the technology gap with China. South Korea's semiconductor giants samsung electronics and SK hynix have begun mass production of memory chips with the world's top technology, accelerating the gap with China. [...]
For capacitance installation, the first thing to mention is the installation distance. The capacitance with the smallest capacitance has the highest resonant frequency and the decoupling radius is the smallest, so it is placed closest to the chip. The larger ones can be a little bit further away, and the outermost ones have the largest [...]
However, due to the fierce market price competition, the cost of PCB board material is also in the rising trend, and more and more manufacturers monopolize the market with low price in order to enhance the core competitiveness. However, behind these ultra-low prices, is to reduce the cost of materials and process manufacturing costs to [...]
Making PCB board is not a simple process to complete the board, drill a hole on the components. PCB production is not difficult, the difficult is to finish the production of fault troubleshooting. Whether it is a personal hobbyist or an industrial engineer, it is quite a headache for PCB circuit board debugging problems, just [...]
Via hole is also known as the conduction hole. In order to meet the customer's requirements, the through hole must be plugged in the PCB process. Through practice, it is found that in the process of plug hole, if the traditional aluminum sheet plug hole technology is changed and the white mesh is used to [...]
