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.
