In the rapid development of science and technology today, a variety of high-tech electronic products emerge in an endless stream, which makes the demand for printed circuit boards increase sharply, manufacturing difficulties are becoming higher and higher
Core plate fabrication → inspection → surface treatment → superimposed semi-curable sheet and RCC→ pressing → positioning of the pattern of the hole → etching the window of the hole →CO2 laser drilling → removal of protective film → metallization of the h
The different types of structures are characterized as follows: 1: flexible single-sided printed board, consisting of only one conducting layer; 2: flexible double-sided printed board, consisting of two conducting layers. 3: Flexible multilayer printed bo
High frequency plate (high frequency microwave printed board) production problems should be paid attention to
With the continuous development of science and technology, especially information technology, the process technology of printed board production is improved accordingly to meet the needs of different users. In recent years, the development of communicatio
The circuit working at high frequency should consider the interference between components. The general circuit should make parallel arrangement of components as far as possible to facilitate wiring;
The board on which the components are installed is bent after welding, and it is difficult to cut the feet of the components neatly. The board can not be installed into the chassis or machine socket, so the assembly plant encountered the board is also ver
Double-sided PCB is a printed board with conductive graphics on both sides. It is usually made of epoxy glass cloth covered with copper foil board. It is mainly used in equipment with high performance requirements.
In the high speed signal transmission line of printed board wire, one is the high frequency signal transmission class of electronic products, the other is the high speed logic signal transmission class of electronic products.
Buried, blind hole structure of the printed circuit board, generally use the "sub-board" production mode to complete, which means that after several times of pressing plate, drilling, hole plating and so on to complete, so precise positioning is...
Circuit board assembly and circuit board processing manufacturers explain high-quality printed board design Part III
The metal core printed circuit board has good heat dissipation. The metal core has large heat capacity and high thermal conductivity, which can quickly dissipate the heat inside the board. If the metal core is connected with the shell and the external rad
Kingford is a PCB company engaged in the production and assembly of circuit boards. We not only sell PCBA, but also have many strategies related to PCB design and PCB proofing. Next, let me introduce you to some matters related to PCB.
