In the electronics industry, collaborative work by interdisciplinary teams is critical to successful product development. The expertise of an electronic design specialist needs to be backed up by mechanical and electrical capabilities to create powerful p
CM needs to establish good business relationships with various parts suppliers, circuit board manufacturers on which PCBS are based, and various engineering services and quality testing services.
There are many kinds of surface treatment of the circuit board. PCB proofing personnel should choose according to the performance and requirements of the board.
The finger contains a number of exposed copper pads that are actually part of the PCB wiring. Usually to connect, we insert the gold finger on one PCB into the appropriate Slot on the other PCB (generally called an expansion Slot).
The surface of the board in machining (drilling, laminating, milling, etc.) process caused by oil or other liquids contaminated with dust pollution surface treatment phenomenon.
Different resin systems and substrate materials are used, and different resin systems will lead to significant differences in the activation effect of copper sinking treatment and copper sinking treatment.
Reducing line width and line spacing is to maximize the use of limited area, and increasing the number of layers is to use space. The circuit mainstream of future circuit boards will be 2 to 3mil, or smaller.
How to improve SMT SMT processing efficiency: first, advance work preparation, second, ensure the SMT SMT machine running time balance, third, equipment operating parameters
The trial-production process of six types of modules generally carried out by domestic counterparts is mainly after determining the main circuit, designing the compensation circuit, carrying out a large number of scheme design and sample production.
the growth rate is the passive components and PCB as the representative of the component plate. 5G substrates, such as soft boards, high-end high-speed materials and PCB, are comprehensively distributed, benefiting from the strong flexibility of 5G and th
Vertical refers to the component body perpendicular to the circuit board installation, welding, its advantage is to save space, horizontal refers to the component body parallel and close to the circuit board installation, welding, its advantage is that th
linear expansion coefficient and glass transition temperature. The PCB of substrate with excessive expansion coefficient often leads to the fracture failure of metallization hole after welding and assembly.
