Assemblability.

PCB products are not only convenient for standardized assembly of

various components, but also can be automated and large-scale mass production.At the

same time, PCB and various components assembly parts can also be assembled into larger

parts, systems, until the complete machine.
Maintainability.

Because PCB products and various component assembly parts are

standardized in design and mass production, these parts are standardized as

well.Therefore, once the system fails, it can be replaced quickly, conveniently and

flexibly, and the system can work quickly.There are, of course, many more examples to

go on.Such as miniaturization of the system, light weight, signal transmission speed

and so on.

PCB packaging

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.
