Optimization design technique of circuit board heat dissipation

Optimization design skills of circuit board heat dissipation :1. Heat dissipation by PCB board itself,2. High heating device with radiator, heat conduction plate,3. For the use of free convection air cooling equipment, the integrated circuit is arranged i

The harm of waste circuit board and how to recycle circuit board

The establishment of more and more circuit board recycling plants, to a large number of waste circuit boards to provide the final place, but also to better protect the environment and their own health.

PCB(printed circuit board) manufacturing process and process details

To summarize, the production process of a typical pcb factory is as follows: blanking → inner fabrication → pressing → drilling → copper plating → outer fabrication → soldering paint printing → text printing → surface treatment → contour processing.

What is the difference between flexible and rigid circuit boards?

Soft board is a printed circuit board made of flexible insulating material, which has many advantages that rigid printed circuit boards do not have. Rigid circuit boards can be high-density.

Various prevention methods of silver plating process of PCB circuit board

Five common silver plating defects of multilayer circuit boards have been solved by solution manufacturers, equipment manufacturers and PCB factories, and some methods have been found to prevent and improve them.

What are SMT patch, PCB circuit board, PCBA processing and DIP plug-in respectively

What are SMT patch, PCB circuit board, PCBA processing and DIP plug-in respectively? First, SMT is one of the basic components of electronic components, which is called surface assembly technology; second, PCB is the most important component of electronic

Five general types of PCB circuit boards are introduced

Five general types of PCB circuit boards: single-sided circuit boards, double-sided circuit boards, multilayer circuit boards, rigid circuit boards, flexible circuit boards

Precautions for urgent proofing of PCB circuit board

Enterprises should pay attention to the circuit board proofing and proofing manufacturers of engineers and operators for good communication, and in the delivery of proofing materials when carefully check the relevant documents.

Circuit board EMI standard

High density and high speed will increase the radiation of the system, while low pressure and high sensitivity will reduce the immunity of the system. EMI is a threat to the safety, reliability and stability of electronic eq

PCB circuit board 4 special electroplating methods

PCB circuit board four special plating methods: finger plating, through hole plating, coil continuous selection plating, brush plating.

Why do multilayer circuit boards do impedance

PCB impedance refers to the resistance and reactance of the parameters, the alternating current plays an obstruction role. Impedance processing is essential in PCB circuit board production.
