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 […]

Process introduction and technical points analysis of copper deposition process for evi circuit boards Chemical copper is widely used in the production and processing of printed circuit boards with through holes. Its main purpose is to deposit a layer of copper on the non-conductive substrate through a series of chemical treatment methods, and then thicken […]

PCB proofing production is developing in the direction of high density, high precision, fine aperture, fine wire, fine pitch, high reliability, multilayer, high-speed transmission, light weight and thinness. At the same time, production is developing in the direction of increasing productivity, reducing cost and pollution, and adapting to multi-variety and small batch production. The technical […]

In the electronic world, PCB or circuit board is the most indispensable part of any electronic equipment. Because they are hidden under the shell of electronic devices, they are often ignored, but they are indeed the backbone of any device, electronic products and equipment you own. PCB (Printed Circuit Board) houses all the electronic components […]

Multi-layer PCB is beneficial to products because they can handle greater complexity. Computers, telephones and medical equipment are some application examples that benefit from multi-layer design. However, the use of multilayer printed circuit boards will become a key problem to connect these layers to each other. If you don’t connect each layer to the corresponding […]
