It should be noted that choosing the appropriate PCB training tutorial class is not only a matter of price, but also related to the credibility of training institutions and teachers. For example, PCB training institutions with rich teaching experience and high-quality teachers may be more suitable for the vast majority of students than cheap institutions.
Brief introduction of PCB
PCB (printed circuit board), that is, printed circuit board, is one of the important components of electronic industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers, communication electronic equipment and military weapon systems, as long as there are electronic components such as integrated circuits, printed boards are used to electrically interconnect the components. Printed circuit board (PCB) is composed of insulating bottom plate, connecting wires and bonding pads. It is used to assemble and weld electronic components and has the dual functions of conducting wires and insulating bottom plate.
It can replace complex wiring and realize the electrical connection between components in the circuit, which not only simplifies the assembly and welding of electronic products, but also reduces the workload of traditional wiring and greatly reduces the labor intensity of workers. But also reduces the volume of the whole machine, reduces the product cost and improves the quality and reliability of electronic equipment. The consistency of printed circuit board products is good, and standardized design can be adopted, which is beneficial to realize mechanization and automation in the production process.

After electronic equipment adopts printed boards, due to the consistency of similar printed boards, manual wiring errors can be avoided, and automatic insertion, welding and testing of electronic components can be realized, thus ensuring the quality of electronic equipment, improving labor productivity, reducing costs and facilitating maintenance.
At the same time, the whole assembled printed circuit board can be used as an independent spare part, which is convenient for the interchange and maintenance of the whole machine products. Printed circuit boards have been widely used in the manufacture of electronic products.
