Copper cladding is to use the idle space on PCB as the datum plane and then fill it with solid copper. These copper areas are also called copper filling. The significance of applying copper is to reduce the impedance of ground wire and improve the anti-interference ability; Reduce voltage drop and improve power efficiency; Also, […]

Hai hi3518EV300 processor, as a new generation of consumer cameraSOC, integrates a new generation of ISP and the latest H265 video compression encoder in the industry. It leads the industry in low bit rate and high image quality. At the same time, it detects human figures and supports intelligent applications such as face and abnormal […]

Whether the amplifier gets current from this power supply or another power supply depends on the instantaneous polarity of the signal on the load. The current flows from the power supply, passes through the bypass capacitor, and enters the load through the amplifier. Then, the current returns to the ground plane from the ground terminal […]

In the design of pcb, we are pulling wires except the layout, so there are some awkward requirements for the outgoing line. It’s not just a random one. Let’s learn with Xiaobian! 1. In order to meet the production process capability requirements of domestic PCB factories, the conventional wiring line width is ≥4mil(0.1016mm) (3.5mil, i.e. […]

If there is a lack of effective communication between PCB designers in the project, several different versions of PCB design data may be generated, and numerous repetitive designs among team members may also occur. If different versions of design data can’t share a unified standard and format, it will inevitably cause communication barriers and management […]

Pcb3w design principle In PCB design, in order to reduce the crosstalk between lines, the line spacing should be large enough. When the line center spacing is not less than 3 times the line width, most electric fields can be kept from interfering with each other, which is the 3W rule. The 3W principle means […]

When designing PCB pads in PCB design, it is necessary to design them in strict accordance with relevant requirements and standards. Because the design of PCB pads is very important in SMT chip processing, which will directly affect the solderability, stability and heat transfer of components and the quality of chip processing, what is the […]

1) in 1)PCB design, the small power supply is firstly paved with copper on the signal layer, and then connected by the current-carrying wiring; 2) PCB design 12V and 5V power supply, if it is the input power supply of switching power supply, should be disposed of in the signal layer (surface layer and inner […]

The lamination arrangement of PCB factory is the basis of PCB design of the whole system. If the laminate design is defective, it will eventually affect the EMC performance of the whole machine. Generally speaking, there are two main rules for laminated design: 1. Each wiring layer must have an adjacent reference layer (power supply […]

The circuit board dispensing machine is used for dispensing the circuit board, which is mainly used for waterproofing, dustproof and anticorrosion. Nowadays, many enterprises have put forward higher requirements for the usability and stability of electronic products, and dispensing processing of circuit boards has become an indispensable process. Long-term and effective protection of some sensitive […]
