In PCB proofing, a layer of lead-tin resist is pre-plated on the part of the copper foil that needs to be kept on the outer layer of the board, that is, the graphic part of the circuit, and then the rest of the copper foil is etched away chemically, which is called etching. As the […]

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 […]
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 […]
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 […]
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 […]
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 […]
If you are just beginning to study the design of IoT products, you need to improve in many aspects of PCB design. IoT devices integrate mobility, low power consumption, RF communication, mixed signal function and high-speed data transmission function into a small space. Keeping all these factors in mind will help you design correctly in […]
Today, Xiaobian takes you to learn about the manufacturing process of PCBA. Before we know about the manufacturing process of PCBA, we should first know about PCB, which is the printed circuit board, the foundation and carrier of electronic components and related electrical links. Generally, it is called PCB bare board, while PCBA is a […]
Changsha flexible printed circuit board Welding Operation Steps Before soldering, the soldering flux should be applied to the soldering pad, and the soldering iron should be used to treat it again, so as to prevent the soldering pad from being badly tinned or oxidized, thus causing poor soldering, and the chip generally does not need […]
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. […]
