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 [...]
FPC flexible circuit board with wiring of high density, light weight, thin thickness, good bending property characteristics, widely used in smart phones, FPC flexible circuit board of the smart phone is mainly used for the connection parts and motherboard, display module, fingerprint module, camera module, antenna, vibrator, etc., as the camera to three, four taken [...]
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 [...]
In the past ten years, my country's electronic information industry has developed rapidly and the scale of the industry has continued to expand. China has become the world's largest consumer electronics market, and the upstream and downstream industrial chain fully matches the needs of the PCB industry. Mobile electronic products such as smart phones are [...]
The copper foil materials used for FPC flexible circuit boards are mainly divided into two types: rolled copper and electrolytic copper. It is a conductor layer bonded to the insulating material of the cover film and is etched into the required pattern through various processes. Electrolytic copper foil is deposited on a bright stainless steel [...]
The printed circuit board industry (press plate oil cooling) energy-saving unit adopts high-quality imported twin-screw compressor: the vapor compression chiller includes four main components of the vapor compression refrigeration cycle compressor, evaporator, condenser, and some metering devices. Realize different refrigerants. The emergence of ammonia refrigeration may solve this problem. Ammonia refrigeration will be the future [...]
Circuit boards are also called circuit plywood, circuit insulation boards, which contain a large number of polymer compounds including formaldehyde; after burning, they will release harmful gases and harmful smoke; they are very harmful to the human body. Pay attention to precautions and pay attention to safety at the disposal site.
Let’s talk to everyone: after China’s progress in launching 5G, even the United States is at a loss. They are all sighing, is it true that no one can stop China? So to what extent has our 5G construction reached so far? It can be said that modern society can have such advanced technology, mainly [...]
