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 […]

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 […]

The development of modern science and technology leads to the miniaturization of electronic components and the extensive application of SMT technology and equipment in electronic products. SMT manufacturing device has the characteristics of full automation, high precision and high speed. With the improvement of automation, higher requirements are put forward for PCB design. PCB design […]

China is the global electronic product manufacturing center and the global electronic product consumption market, which provides sufficient market depth for the domestic PCB industry. At the same time, domestic PCB enterprises still have obvious competitive advantages due to the advantages of complete PCB industry chain and sufficient labor resources.   What should aluminum substrate […]

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 […]

During the processing and production of PCBA patches in Changsha, due to some processing techniques and other reasons, some tin beads and slag often remain on the surface of PCBA. These tin beads and slag will cause some hidden dangers for the use of products, such as short circuit of circuit boards after loosening. Here, […]
