PCB with insulation board as the base material, at least attached with a conductive graphic, and cloth holes, used to replace the chassis of the previous device electronic components, to achieve the mutual connection between electronic components.
The manufacturing process of printed board is still more complex, to go through the light painting, photographic plate and other chemical processes, consume more materials, longer cycle, high cost.
In the core structure, all the conductive layers in the circuit board are coated on the core material; In the foil-coated structure, only the internal conductive layer of the circuit board is applied to the core material, and the external conductive layer
Since 2005, the world's electronic circuit industry technology has developed rapidly, mainly focusing on passive component PCB, inkjet PCB process, laser direct imaging technology, optical technology PCB and nanomaterials in PCB board applications.
The PCB layout determines the performance of a switched power converter. You don't have to spend countless hours debugging EMI, noise, signal integrity, and other issues associated with poor layout.
Embedded copper printed circuit board has the characteristics of high thermal conductivity, high heat dissipation and saving board space, which can effectively solve the heat dissipation problem of high-power electronic components.
It has been proved that the reliability of electronic equipment will be adversely affected even if the circuit diagram is designed correctly and the printed circuit board is not designed properly.
The development level of printed circuit board industry can reflect the development speed and technical level of electronic industry in a country or region to some extent.
In this way, the printed circuit or printed circuit of the finished board called printed circuit board, also known as printed board or printed circuit board.
With the continuous improvement of automobile safety, comfort and intelligence, PCB (printed circuit board) products are also facing the development of intelligent and green needs.
Printed circuit board is a bridge that carries electronic components and connects circuits. It is widely used and is an indispensable electronic component in modern electronic information products.
In the process of circuit board production, the waste water mainly contains copper, chromium, nickel, zinc, acid and alkali pollution components. If the above wastewater is not effectively treated, it will do harm to human beings, fish, plankton and the e
