Manufacturing process of industrial control medical double-sided PCB In order to avoid electromagnetic radiation generated when high-frequency signals pass through printed wires, the following points should also be paid attention to when wiring industrial control medical double-sided PCB: 1. Try to reduce the discontinuity of the wires of the double-sided PCB circuit board for industrial […]

A friend asked Xiaobian, in the process of producing FPC, whether we are single-chip production or mass production. Here Xiaobian will talk about it in detail through the actual experience of the factory. In the production process of FPC, in order to save cost, improve production efficiency and shorten production cycle, imposition is always adopted […]

The so-called copper cladding is to take the idle space on the flexible circuit board as the reference plane, and then fill it with solid copper. These copper areas are also called copper filling.The significance of copper coating is to reduce the ground wire impedance and improve the anti-interference ability;Reduce voltage drop and improve power […]

Flexible circuit board (FPC) is a kind of flexible printed circuit board which is made of polyimide or polyester film with high reliability and excellent flexibility.FPC is also known as soft circuit board and flexible circuit board. It is favored for its light weight, thin thickness, free bending and folding. FPC is a technology developed […]

The wiring diagram behind the physical PCB and the factory drawings are two different things. PCB factory drawings describe the physical and electrical attributes in the circuit diagram of “Gerber data file”. The two documents complement each other. Memo needs to define options and exceptions. Although there are some specifications that drive the PCB design […]

1. Single-sided flexible board Lowest cost. When the requirements for electrical performance are not high and single-sided wiring is possible, the single-sided flexible circuit board should be selected. This most common form has been used in commercial applications, such as ink cartridges of printers and memories of computers. The single-sided flexible board has a layer […]

Multilayer circuit boards are usually defined as 10-20 or more advanced multilayer circuit boards, which are more difficult to process than traditional multilayer circuit boards and require high quality and reliability. Mainly used in communication equipment, high-end servers, medical electronics, aviation, industrial control, military and other fields. In recent years, the market demand of high-rise […]

An integrated circuit board is a carrier for carrying integrated circuits. But it is often said that the integrated circuit board should also be brought with it. The integrated circuit board is mainly composed of silica gel, so it is generally green. Integrated circuit board (IC) adopts semiconductor manufacturing technology. Many transistors, resistors, capacitors and […]

During the use of the circuit board of medical equipment, a large current will be generated in a short time. If a large current is generated for a long time, a large amount of heat will be generated in the main line board and circuit of the equipment. Then it must be protected by a […]

When we use the flexible printed circuit board, do you know its basic structure? Do you know what it is made of? Let’s split it to give you a simple understanding of the basic structure of flexible printed circuit board. 1. copper foil substrate (Copper Film) Copper foil: basically divided into electrolytic copper and rolled […]
