PCB or printed circuit boards, also known as printed cables board, is an important electronic component, it’s the support of electronic components which the electronic components are the carrier of electrical connections. Because it is produced electronically, it is called a “printed” circuit board. PCBs evolve from one layer to two-sided, multi-layered and flexible, and still maintain their own developmental trends. Because it continues to develop high-precision, high-density, and high-reliability direction, and continue to reduce volume, reduce costs, improve performance, make PCB in the future of electronic equipment development projects while maintaining a strong vitality. PCB Assembly China is one of the best PCB assembly service.
PCB assembly is a relatively good job, in the whole process, there will be many special requirements, we not only to check whether the correct cabling, operation according to the norm, there are some mild precautions, and scheme examination Diagram is also a key link.
So, how do we check the connection?
- According to the circuit diagram to check the installation of the channel, according to the wiring, in accordance with certain commands to check the installed path.
- According to the actual line control schematic diagram, take the component as the center to check
