One of the reasons I like being a field application engineer for NCAB Group is to be able to interact with all kinds of customers. They have different ideas, but they all want to create cool products. I have noticed that customers have gradually realized that PCB is a key component of products, but they [...]
The circuit board factory can make employees more deeply understand the connotation of quality culture through the interaction between quality culture construction and management work. The quality culture construction work must be attended by all the members of the circuit board factory in order to be truly effective, and it must be persisted for a [...]
PCB wiring skills 1. The edges of the input end and the output end should be avoided adjacent and parallel to avoid reflection interference. If necessary, ground wire should be added for isolation. The wiring of two adjacent layers should be perpendicular to each other. Parasitic coupling can easily occur in parallel. 2. Add decoupling [...]
Questions about the color of PCB circuit boards Most of the circuit boards we use are green? Why is that? In fact, PCB circuit boards are not necessarily green. It depends on what color the designer wants to make it. Under normal circumstances, we choose green, because green is less irritating to the eyes, and [...]
Our company mainly produces and processes rigid PCB boards. The information needed to make circuit boards is as follows: 1.PCB board information (make the drawings of the circuit board) 2. Process: Surface production process: spray tin, gold plating, immersion gold, nickel plating, oxidation resistance. (Choose one) Solder mask color: dark green, light green, blue oil, [...]
FPC flexible circuit boards are widely used in smart phones due to their high wiring density, light weight, thin thickness, and good flexibility. The FPC flexible circuit boards in smart phones are mainly used for the connection of parts and the motherboard, like Display modules, fingerprint modules, camera modules, antennas, vibrators, etc., with the continuous [...]
With the miniaturization of various smart products, the density of components on circuit boards is increasing. In order to improve the quality of circuit boards, strict product tests and quality inspections must be passed before they leave the factory. X-ray inspection equipment is mainly used to detect process defects of circuit boards and find out [...]
For precision parts, processing is very strict. The processing program includes cutting in, cutting out, etc. There are specific requirements for size and accuracy, such as how many micrometers are floating up and down 1mm. If the size difference is too large, it will become waste at this time, which is equivalent to reprocessing. This [...]
As a new type of sensor, the optical fiber sensor has the incomparable advantages of traditional sensors, such as: high measurement accuracy, large measurement dynamic range, fast response speed, immunity to electromagnetic interference, explosion-proof, flame-proof, anti-corrosion, easy long-distance measurement and Reuse, small size, simple structure, high mechanical strength, etc. In the early days, optical fibers [...]
With the development of science and technology, the requirements for soldering processes in electronic processing are getting higher and higher. The soldering process of traditional soldering soldering machines can no longer meet the precision welding of some small devices. At this time, laser soldering machines can just make up for the shortcomings of traditional soldering [...]
