Dip soldering is a welding method, mainly used in the plug-in process and SMT red rubber surface, it will be pre-inserted components of the printed circuit board immersed in the molten state of the solder, so as to complete the circuit board on all the soldering points of the welding. The method is mainly used

Rogers pcb substrate, using the proprietary amide resin material developed by Rogers, this material gives it excellent dielectric properties, thermal stability and mechanical strength. Even under extreme working environments such as high temperature and high humidity, high frequency and high speed, Rogers PCB boards are able to maintain stable operation, demonstrating their strong adaptability and

RF circuit board design is an important branch in the field of electrical engineering, which focuses on the design, optimization, and implementation of circuits and systems used to process Radio Frequency (RF) signals. RF signals usually refer to electromagnetic signals with frequencies between several thousand hertz and several hundred gigahertz, and are widely used in

The principle of multilayer PCB design is to lay out different circuit components according to their functions and locations, and then connect them through wires. During the design process, various factors need to be considered, such as the selection of parameters for components such as resistors, capacitors, inductors, etc., the routing of signal wires, and

Understanding the classification and processes of PCB manufacturing processes and mastering basic PCB manufacturing process capabilities are the foundation for PCB manufacturability design. Classification of printed circuit boards Printed circuit board according to the production material can be divided into rigid printed circuit board and flexible printed circuit board. Rigid printed circuit boards are phenolic

The drilled hole tolerance of a pcb board is the tolerance between the diameter of the holes or slots drilled or milled during the PCB manufacturing process and the design requirements. This tolerance requirement is to ensure that the components on the board are installed correctly and can be well connected. Generally, the hole diameter

Flip chip packaging technology, also known as FC packaging technology, is an advanced integrated circuit packaging technology. In traditional packaging technology, the chip is encapsulated at the bottom and connected to the package substrate through gold wires. Flip chip technology, on the other hand, flips and mounts the chip directly onto the package substrate, and

Electrostatic spray coat is the use of high-voltage electrostatic field to make negatively charged paint particles along the electric field in the opposite direction of the directional movement, and will be adsorbed on the surface of the workpiece paint particles of a spraying method. Electrostatic spray equipment consists of spray gun spray cup and electrostatic
