The reason the PCB has been used more and more widely is because it has many unique advantages, including the following.
1. Can be densified.For decades, the high density of printed boards has been able to develop with the improvement of integrated circuit integration and installation technology.
2. High reliability.Through a series of inspections, tests and aging tests, the PCB can be guaranteed to work reliably for a long time (service life, generally 20 years).
3. Designability.For all kinds of performance requirements of PCB (electrical, physical, chemical, mechanical, etc.), we can realize the design of printed board through design standardization, standardization, etc., with short time and high efficiency.
Productive.Adopt modern management, can carry out standardization, scale (quantity), automation and other production, to ensure the consistency of product quality.
4. Testability.Set up a relatively complete test method, test standard, a variety of test equipment and instruments to detect and identify the quality and service life of PCB products.
5. Assemblability.PCB products are not only convenient for various components to be standardized assembly, but also can be automated, large-scale mass production.At the same time, PCB and various components assembly parts can also be assembled into larger components, systems, until the complete machine.
6. Maintainability.Because PCB products and various component assembly parts are standardized in design and mass production, these parts are also standardized.Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the work of the system can be restored quickly.
There are, of course, many more examples.Such as miniaturization of the system, light weight, signal transmission speed and so on.

1. The PCB circuit board needs to be vacuum packed with colorless gas bead plastic bags, and the bags should be attached with necessary desiccant and ensure that the bags are tightly packed.Can not contact with wet air, avoid PCB circuit board surface spray tin, gold deposition and welding pad parts are oxidized and affect the welding, is not conducive to production.
2. When packing the PCB circuit board, it is necessary to surround the box with a layer of bubble film. Because the bubble film has good water absorption, it can absorb water and moistureproof.In addition, moisture-proof beads can be placed in the case.
3, put the PCB circuit board classification, label.After sealing, the box must be kept away from the wall and the floor.Store in a dry, ventilated place and avoid direct sunlight.
4, the warehouse temperature of PCB circuit board storage is best controlled at 23±3℃, 55±10%RH, under such conditions, gold, gold, tin spraying, silver plating PCB circuit board surface treatment can generally be stored for 6 months, silver, tin, OSP surface treatment PCB circuit board can be stored for 3 months.
5, for a long time do not use the PCB circuit board, it is best to brush a layer of three anti paint, three anti paint can be moisture-proof, dustproof, anti oxidation.In this way, the storage life of PCB circuit board will be increased to 9 months.
About the PCB board several kinds of packaging, introduced to this.In fact, the storage time of PCB circuit board is related to the surface treatment. Gold plating and electric gold plating are the longest storage time. Under the conditions of constant temperature and humidity, they can be stored for two or three years.Do a good job of PCB circuit board storage can better extend the service life of the circuit board, is a problem can not be ignored.
