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 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.
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.
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.
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.
In the PCB industry using laser marking two-dimensional code technology, can realize PCB production, process, quality traceability, and realize the automation, intelligent management requirements.
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: single-sided circuit boards, double-sided circuit boards, multilayer circuit boards, rigid circuit boards, flexible circuit boards
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.
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 four special plating methods: finger plating, through hole plating, coil continuous selection plating, brush plating.
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.
