ircuit board

Aerospace ceramic circuit board

Compared with earlier standard ceramic materials, the new technology ceramics have improved durability, inertness and chemical properties. Even the physical properties have changed. Ceramic materials do not break down, soak or absorb moisture in large qua

Present situation and future trend of printed circuit board industry

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.

Technical requirements for substrates for PCB circuit boards

In order to improve the technical performance of the printed circuit board, we must first improve the performance of the printed circuit substrate board, and ensure the demand for high density and fine wire, copper foil, laminated insulating dielectric sh

6 Ways to Make your own circuit Board

There are many ways to make printed boards under amateur conditions, each has its own characteristics. When painting, we should pay attention to the hand force to the proper weight, too heavy paint film is too thick, the line will run lace, too light line

Circuit board recovery

The content of PCB circuit board metal is up to more than 40%, so there is a waste PCB recycling industry. Refining the metal in the circuit board, the remaining non-metallic waste powder, can also be used as an important filling material in polymer compo

The disposal method of waste circuit board

The disposal methods of waste PCB include crushing, separation, supercritical technology treatment, heat treatment (it mainly includes incineration, vacuum cracking, microwave, etc.), hydrometallurgy, biotechnology.

Printed circuit board wastewater treatment

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

PCB proofing of circuit board

After the PCB size is determined, the pendulum position of the special component is determined. According to the function unit, the layout of all components of the circuit board.

​ Design and analysis of mixed signal printed circuit board

The difficulty of PCB design is that there are more and more devices with different digital logic, and these circuits with different logic thresholds and voltage swings must be designed together on a PCB multilayer circuit board.

The difference between circuit board and chip

Circuit board is to assist electronic components to better play their due performance, chipset mainly determines the function of the motherboard, and then affects the performance of the whole computer system, is the core component of the motherboard.

Flexible circuit board production flow chart and advantages and disadvantages

Flexible circuit board has the characteristics of short, small, light and thin; It has the characteristics of high assembly density and small volume. There are high cost, long cycle, complex inspection methods, etc., which is a process that all FPC circui

Skills required for RF circuit board engineers

In the mobile phone terminal, the most important core is the RF circuit board and baseband circuit board. Rf circuit board responsible for RF transceiver, frequency synthesis, power amplification; Baseband circuit boards are responsible for signal process
