In fact, the displacement of components in smt processing is a bad phenomenon in SMT factory. With the development of science and technology and the improvement of people’s living standard, the pursuit of electronic products is becoming more and more miniaturized and precise. However, the traditional DIP plug-in in SMT small batch chip processing factory […]

Where are the OEM manufacturers in Changsha? Circuit board proofing refers to the trial production of printed circuit boards before mass production. It is mainly used in the process of small batch trial production in the factory after the electronic engineer designs the circuit board, that is, circuit board proofing. Generally, there is no specific […]

What is PCB high frequency board? Changsha high-frequency board refers to a special circuit board with high electromagnetic frequency, which is used for PCB in high-frequency (frequency greater than 300MHZ or wavelength less than 1m) and microwave (frequency greater than 3GHZ or wavelength less than 0.1m) fields. It is a circuit board produced by using […]

Metal core PCB is not very common in consumer products, but it can be found everywhere in industries, aerospace, lighting systems, power electronics and other fields that require high reliability. High-power systems generate a lot of heat, and it is necessary to quickly remove the heat to prevent component failure. Similarly, low-power systems may be […]

Product name: 10-layer pcb production Introduction of 10-layer pcb board: PCB(Printed Circuit Board) is also called: circuit board, printed circuit board, printed circuit board, Almost all electronic devices can be used. As long as there are electronic components such as integrated circuits, printed boards should be used for their electrical interconnection. In the process of […]

What problems should be paid attention to when PCB proofing components are used? In PCB proofing, components with high sensitive voltage threshold should be used as much as possible on the premise of meeting the requirements of circuit functions. Because the electrostatic and discharge sensitivity of a circuit board depends on the components with the […]

As the name implies, rigid-flexible printed circuit boards are manufactured by the combination of rigid and flexible circuit boards. The two boards are then permanently interconnected to form various types of PCBs. In the manufacturing process of rigid and flexible circuit board, some factors and precision must be considered to produce the perfect final product. […]

With the rapid development of electronic technology, PCB manufacturers can only find a way out in the highly competitive PCB industry by actively developing and innovating production technology on the basis of recognizing the development trend of PCB technology. PCB manufacturers should always keep a sense of development. Here are some views on the development […]

Consideration of the aperture size of PCB proofing pad When PCB proofing plug-in component pads, the pad size should be appropriate. If the pad is too large, the solder spreading area will be larger, and the solder joints formed will not be full, while the copper foil surface tension of the smaller pad will be […]

There are many kinds of resistors, such as carbon film resistor, cement resistor, metal film resistor and wire wound resistor. Special resistors include piezoresistors, thermistors and photoresistors. Different types of resistors have certain differences in their characteristic parameters, and the points to be considered in circuit use are also different. For engineers who are new […]
