Design and optimize the high-speed BGA package and PCB differential interconnection structure, focusing on the analysis of the differential wiring method of the package and PCB interconnection area, signal layout method, signal hole/ground hole ratio, wiring layer and via stubs. The specific impact of high-speed differential signal transmission performance and crosstalk. The full-wave electromagnetic field [...]

The hardware shield is a metal cover, its function is to shield the external electromagnetic wave's influence on the internal circuit and the electromagnetic wave generated inside to radiate outward. Moreover, hardware shielding covers are widely used in walkie-talkies, connectors, mobile phones, computers, GPS, digital products, aviation and other fields. Shield manufacturers who have been [...]

Almost every electronic device manufactured uses a printed circuit board (PCB). From our smart phones to microwave ovens, you will find PCBs. The exact type of PCB varies by application: some have multiple layers, some are flexible. What most PCBs have in common is a certain way of protecting the environment. Regarding PCB protection, there [...]

FPC circuit board production process At present, the production process of FLEXIBLE circuit board mainly includes material opening, drilling, VCP, copper plating, dry film sticking, exposure, development, etching, dry film drying, decontamination cleaning, protective film sticking, lamination, pure tin, gold plating, silk-screen printing, punching, electrical testing, reinforcement film fitting, functional testing and other processes. The [...]

Now most of the electronic parts are almost used SMT hit a complete, even DIP parts can use PIH (Paste - - Hole) In the way when SMT play, usually a SMT line will be fast, slow domestic machine, some will add a special-shaped parts play a machine, small parts with fast machine, large parts [...]

Parallel plate light path diagram scanning system, the parallel plate instead of four optical wedge module of optical wedge in the translation, the parallel plate according to the tilt Angle of a fixed place to produce a translation of the light beam, its biggest advantage is lower cost and using life is longer, the disadvantage [...]

Organic silica gel is a kind of adhesive with adhesion property. After curing, the adhesive has the properties of sealing and waterproof. Especially, it can play the insulating property in electric appliances. At present, many electrical components or circuit boards are used in bonding and fixation. How about the performance of silicone bonding circuit board? [...]

PCB (PrintedCircuitBoard), the Chinese name is printed circuit board, also known as printed circuit board, printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a "printed" circuit board. As PCB size [...]

For a long time, PCB buyers have always had doubts about the color of PCB, and they don't know what color PCB board is of high quality. How does the color of the PCB affect its performance? First, as a printed circuit board, PCB mainly provides interconnection between electronic components. There is no direct relationship [...]
