printed circuit board, is an important electronic component, is the support body of electronic components, is the electrical connection provider of electronic components. Because it is made using electronic printing, it is called a "printed" cir...
For optimal performance in lighting applications, PCBS must be designed for use with leds to maximize heat transfer capacity.
. In the design of PCB boards and the production of PCB boards, engineers should not only prevent PCB boards from being accidentally encountered in the manufacturing process, but also avoid design errors.
As electronic products to "light, thin, short, small" direction of progress, PCB also to high density, high difficulty degree of progress.
There are many exquisite PCB presets, whether it is the principle of presets or components mix and match, are strict requirements.
PCB multilayer board is the multi-layer line layer, between each two layers is the media layer, the media layer can do very thin.
When the infrared frontal temperature gun is aimed at and close to the distance between the measured object and the tube measured by the sensor, the infrared sensor plate will collect the temperature and convert it into an electrical signal.
The main reason of electromagnetic interference caused by ground wire in PCB is the impedance of ground wire. When an electric current flows through a ground wire, a voltage is generated on the ground wire. This is ground noise. Driven by this voltage, a
Copper clad plate is the basic material of electronic industry, mainly used in the processing and manufacturing of printed circuit board (PCB), widely used in TV, radio, computer, computer, mobile phone, communication and other electronic products.
in the process of PCB copying board, PCB scanning is undoubtedly the first step of all processes. Therefore, we first get a good PCB board, and then it must be scanned by the computer, and then backup the relevant parameters and the original PCB layout.
PCB copy board and chip, the two are more like the relationship between the lips and teeth, think about it carefully, PCB copy board is like the shelter of the chip, without the shelter, the chip can only wander around, and can not play their role.
Copy board is also called cloning or imitation, is a product design of PCB board reverse technology research, copy board is equal to copy board, copy the circuit board on the hand, and then mass production.
