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, […]

VIA, the copper foil circuit between the conductive patterns in different layers of the circuit board is conducted or connected by this hole, but the copper-plated hole of the lead leg of the component or other reinforcing materials cannot be inserted. Printed Circuit Board (PCB) is formed by stacking many copper foil layers. Copper foils […]

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 rapidly growing field of electronic and telecommunication engineering requires technological innovation, engineers and scientists are constantly looking for novel ways to improve the quality, life cycle and reliability of final products. Therefore, flexible PCB materials are the focus of current research. Flexible PCB can be found in almost all electronic devices around us […]

Pcb proofing and cutting dimensions ① Maximum panel size: 530 * 622mm (tinplate: 450 * 622mm/MAX. Depending on the equipment capacity) ② Pay attention to the latitude and longitude of boards with more than six floors (they must be the same), which will easily cause poor compression. ③ The size of the reserved surface of […]
