Circuit board processing provides the function of the role for electronic products
First: to provide integrated circuits and other electronic components are fixed, the assembly of mechanical support.
Second: to ensure the quality of the electronic equipment, improve the labor productivity, reduce the cost, and easy maintenance.
Third: to provide automatic soldering resistance welding graphics, instrumentation for components, inspection and maintenance to provide identification characters and graphics.
Fourth: the realization of integrated circuits and other electronic components between the wiring and electrical connections or electric insulation.
To provide the required electrical properties, such as the characteristic impedance, etc.
Fifth: electronic equipment after the circuit board processing, due to the consistency of the same kind of PCB, so as to avoid the artificial connection error, and can realize automatic instrumentation or SMT electronic components, automatic soldering, automatic detection.
One hundred million giant electronic computers, communications equipment and spacecraft, as long as there are integrated circuits and other electronic components, to electrical interconnection between them, is inseparable from the circuit board processing.
May say in all electronic products, especially in the process of the development of the intelligent electronic product, the success of the most basic factor is the circuit board processing of the product design and manufacturing technology, so the circuit board processing plays a role in electronic products is very important.
Circuit board processing principle of the graph is a blueprint, can realize the function of circuit users need.
The design of the circuit board processing mainly refers to the design of the landscape, need internal electronic components, metal wire, the layout of the hole is connected with the external, electromagnetic protection, heat dissipation factors, crosstalk, etc.
Circuit board vendors need for fast, medium speed and low logic circuit, placed close to the connector, and logic and memory, shall in principle, scope of the connector.
In this way, to reduce total impedance coupling, radiation and the decrease of the cross.
What are the precautions for circuit board processing and maintenance?
The following simple introduce circuit board maintenance notice: 1, when need to contact with high voltage must be pay attention to safety, do a good job in heavy current prevention measures.
2, pay attention to safety, including PCB and electrical maintenance to take into account the PCB maximum capacity.
3, before the maintenance must first do a good job anti-static, such as wear anti-static work clothes and shoes, wear good anti-static wrist strap.
Maintenance of workbench also want good anti-static processing, such as adding antistatic mesa.
So the success of the circuit board processing, one should pay attention to inner quality, the second is aesthetic overall, both more perfect to think that the product is a success.
Considering the PCB layout of the whole beautiful, on a piece of circuit board processing, components in the layout of the requirement for balanced, density and orderly.
In addition there is a important problem, size problem.
Circuit board processing size to match the processing drawings' production, conform to the requirements of the PCB manufacturing process and the position mark.
