Vias, holes on the circuit board, connect the lines between different layers, and change the circuit board from a planar structure to a three-dimensional structure.It is too difficult for single-layer lines to not cross, and double-layer or more layers must be connected through vias. Through the copper on the hole wall, the circuit copper wires […]

The sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to become stronger and stronger, so PCB design has become more difficult. How to improve the anti-interference ability of PCB has become one of the key issues that many engineers pay attention to. This article will introduce […]

Technology of Via and Back Drilling in PCB Production Friends who have done PCB design know that the design of PCB vias is actually very particular, so what are the technologies of PCB State Control? Today, I will share with you the technical knowledge of vias and back drilling in PCB. Via design in high-speed […]

What is a via Vias, holes on the circuit board, connect the lines between different layers, and change the circuit board from a planar structure to a three-dimensional structure. It is too difficult to avoid crossing of single-layer lines, and double-layer or more lines must be connected through vias. Through the copper on the hole […]

In the production process of ceramic PCB circuit board processing, laser processing mainly includes laser drilling and laser cutting. Ceramic materials such as alumina and aluminum nitride have the advantages of high thermal conductivity, high insulation and high temperature resistance, and are widely used in the fields of electronics and semiconductors. However, ceramic materials have […]

Multilayer PCB is used as the “core main force” in the fields of communication, medical treatment, industrial control, security, automobile, electric power, aviation, military industry, and computer peripherals. As the product features more and more and the circuits become more and more dense, the production difficulty becomes more and more difficult. At present, domestic PCB […]

Both DPC ceramic substrates and LTCC ceramic substrates are ceramic-based circuit boards with good thermal conductivity, high insulation and high air tightness. In various fields of application products, what is the difference between DPC ceramic substrates and LTCC ceramic substrates? 一、The production process of DPC ceramic substrate and LTCC ceramic substrate is different 1.DPC ceramic substrate and process characteristics The DPC ceramic substrate […]

With the development of society, more and more things are becoming more and more intelligent. The premise of this is to have more circuit board SMD to control these devices, and FPC patch processing is one of the most important links. The quality of FPC SMD processing determines the life and quality of this product. […]

What is PCB copper cladding? Copper pouring is to use the idle space on the PCB as the reference plane, and then fill it with solid copper. These copper areas are also called copper pouring. The significance of copper cladding is: reducing the impedance of the ground wire and improving the anti-interference ability; reducing the […]

PCB proofing refers to the trial production of printed circuit boards before mass production. It is mainly used for electronic engineers to design the circuit and complete the drawing of the PCB, and then conduct a small batch trial production process to the circuit board factory, that is, PCB proofing. The following is an introduction […]

In PCB design, the pad is a very important concept, and PCB engineers must be familiar with it. However, although familiar, many engineers have little knowledge of pads. Today, the circuit bacteria takes you to understand the types of pads and the design standards of pads in PCB design. Pad, the basic unit of surface […]

Gold FingerOn computer memory sticks and graphics cards, we can see a row of golden conductive contacts, which are called “gold fingers”. The Gold Finger (or Edge Connector) in the PCB design and production industry uses the plug of the connector as the outlet for the external connection of the board to the network. Next, […]
