What bus does Dinghai take to Zhoushan driving test center
Bus route: No.50 → No.51, the whole journey is about 18.3km
1. Take No.50 from Sanjiang wharf, pass 18 stops, and reach Donghai intersection station
2. Take No.51, pass 9 stops, and reach the passenger transport center station (you can also take No.1 or No.52)
3. Walk about 30m to Dinghai passenger transport center
Shenjiamen
to
Zhujiajian
to get off at Shenjiamen hotel
1: query function,

4: financial management function (e.g. regular current transfer, etc.)
1. PCB (printed circuit board), Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, is the support of electronic components, is the carrier of electrical connection of electronic components. Because it is made by electronic printing, it is called "printed" circuit board
2. Function of PCB:
after using PCB for electronic equipment, e to the consistency of similar PCB, the manual wiring error can be avoided, and the electronic components can be automatically inserted or pasted, soldered and detected, so as to ensure the quality of electronic equipment, improve labor proctivity, rece cost and facilitate maintenance
extended data:
PCB can be more and more widely used, because it has many unique advantages, as follows:
1, can be high-density. For decades, PCB high density can develop with the improvement of IC integration and installation technology
2. High reliability. Through a series of inspection, test and aging test, PCB can work reliably for a long time (generally 20 years)
3. Designability. For PCB performance requirements (electrical, physical, chemical, mechanical, etc.), PCB design can be realized through design standardization, standardization, etc., with short time and high efficiency
4. Procibility. With modern management, standardization, scale (quantity), automation and other proction can be carried out to ensure the consistency of proct quality
5. Testability. Established a relatively complete test method, test standards, various test equipment and instruments to detect and identify the PCB proct qualification and service life
6. Assemblability. PCB procts are not only convenient for standardized assembly of various components, but also for automatic and large-scale mass proction. At the same time, PCB and various component assembly parts can also be assembled to form larger parts, systems, and even the whole machine
7. Maintainability. As PCB procts and various component assembly parts are designed and proced in a standardized way, these parts are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system can be restored quickly. Of course, there are more examples. Such as making the system miniaturization, lightweight, high-speed signal transmission and so on
the board with a lot of small parts inside the appliance is called circuit board (also called PCB)
circuit board has a history of more than 60 years since its invention. History shows that without circuit board and electronic circuit, flight, transportation, atomic energy, computer, aerospace, communication and home appliances can not be realized. The truth is easy to understand. Chip, IC, integrated circuit are the grain of electronic information instry. Semiconctor technology reflects a country's instrial modernization level and guides the development of electronic information instry. But the semiconctor (integrated circuit, IC) electrical interconnection and assembly must rely on the circuit board. As Kobayashi, the author of Japanese printed circuit board collection, said: & quot; If there is no computer and data, electronic equipment is equal to an ordinary box; Without semiconctors and circuit boards, electronic components would be ordinary stones& quot; PCB is a promising instry in China, with a double-digit growth rate every year. Many foreign orders are put into China, so there are opportunities
for example, the motherboard in a computer is a circuit board
It's the printed circuit board of the main board. Not only the motherboard, as long as the printed circuit board with electronic components is called PCB
