Description
Technical field
The utility model is related to technical field of PCB board more particularly to a kind of multi-layer PCB boards.
Background technology
Printed circuit board { PCB circuit board }, also known as printed circuit board are the suppliers of electronic component electrical connection.It
Development have more than 100 years history；Its design is mainly layout design；Major advantage using circuit board is to subtract significantly
Few mistake connected up and assemble, improves the gentle productive labor rate of Automated water.It can be divided into single sided board, double according to the wiring board number of plies
Panel, four laminates, six laminates and other multilayer circuit boards.Since printed circuit board is not general end product, in name
It is slightly chaotic in the definition of title, such as：The motherboard of PC, referred to as mainboard, and cannot directly be known as circuit board, although main
Have the presence of circuit board in machine plate, but and differ, therefore both when assessing industry it is related cannot but say it is identical.Again for example：
Because there is integrated circuit part to load on circuit boards, thus news media he be referred to as IC plates, but it is substantial he be also not equal to
Printed circuit board.The printed circuit board that we usually say refers to the circuit board of the i.e. no upper component of bare board-.In recent ten years,
China's printed circuit board (Printed Circuit Board, abbreviation PCB) manufacturing is quickly grown, and the gross output value, total output are double
Dibit ranks first in the world.Since electronic product makes rapid progress, price war changes the structure of supply chain, and China has both industry point
Cloth, cost and the market advantage have become the most important printed circuit board production base in the whole world.Printed circuit board develops from single layer
To dual platen, multi-layer board and flex plate, and constantly develop to high-precision, high density and high reliability direction.Constantly reduce body
Product reduces cost, improves performance so that printed circuit board still maintains powerful in the evolution of future electronic product
Vitality.
But traditional PCB plate wiring needs to weld, and working efficiency is low, and is easy plate bursting.
