Description
Technical field:
This utility model is related to multilayer circuit board technical field, specially a kind of multilayer circuit board.
Background technology:
1961, the U.S. was the pioneer first opening multi-layer sheet exploitation, this kind of mode with make multilamellar using plated-through-hole legal system now
The mode of plate is almost identical.Behind Japanese this field across foot in 1963, relevant multiple-plate various conception schemes, manufacture method, then
Gradually popularize in the whole world.Because marching toward the IC epoch with by electric crystal, after the application of computer is increasingly popular, because of Gao Gong
The demand of energyization becomes multiple-plate demand emphasis so that wiring capability is big, transmission characteristic is good.Multi-layer sheet was with gap method originally
Method, Layer increasing method, the logical three kinds of manufacture methods of method of plating are disclosed.When very being taken a lot of work on manufacturing due to clearance hole method, and densification is subject to
Limit, therefore not practical.Layer increasing method is considerably complicated because of manufacture method, though adding the advantage of tool densification, because right at that time
Densification demand and not as now urgently, unknown to the public always, you near then because of the demand day Yin of high density circuit board, then
Degree becomes the emphasis of Ge Jia manufacturer research and development.Lead to method as the plating with the same processing procedure of dual platen, be still multiple-plate main flow system at present
Make method, and positioned between needing lamina when carrying out and plating logical, not so the phenomenon of dislocation easily occurs, causes multilayer wire
Road plate cannot use, and the radiating effect of multiple plate is generally poor, easily cause internal wiring and cannot be carried out normally
Work, for this reason, a kind of it is proposed that multilayer circuit board.
Utility model content:
The purpose of this utility model is to provide a kind of multilayer circuit board, to solve the radiating proposing in above-mentioned background technology
The problem of effect difference.
For achieving the above object, this utility model provides following technical scheme:A kind of multilayer circuit board, including backplate, institute
The top stating backplate is provided with cavity, and the left and right sides wall of described cavity is provided with locating dowel, the left and right sides of described backplate
Wall is provided with louvre, described cavity be internally provided with monolayer wiring board group, and the size of monolayer wiring board group and cavity
Size match, the left and right sides wall of described monolayer wiring board group is provided with the locating slot matching with locating dowel, described
Monolayer wiring board group includes multigroup monolayer wiring board, is provided with insulating barrier described in two groups between monolayer wiring board, described insulating barrier
Surface be provided with radiating groove.
Preferably, the inwall of described cavity is provided with compound adhesive block film.
Preferably, described locating dowel is thermal grease post.
Preferably, the rectangular array-like of described louvre is arranged on the left and right sides wall of backplate, and louvre runs through shield
The left and right sides wall of plate.
Preferably, the rectangular array-like of described radiating groove is arranged in the surface of insulating barrier.
Preferably, the thickness size of described monolayer wiring board group is identical with the depth size of cavity.
Compared with prior art, the beneficial effects of the utility model are:Compared with existing multilayer circuit board, this practicality is new
Type structure is simple, has good radiating effect, by the locating dowel in the cavity and cavity on backplate to monolayer wiring board group
Carry out positioning action, instead of conventional in plate face, and this open up single registration holes and carry out the mode of para-position easily make
Become that para-position direction is unclear, bit errors are larger, matched with the size of monolayer wiring board group by cavity so that will not during para-position
Dislocation occurs, which reduces bit errors, and on the basis of original multilayer circuit board, this utility model increased
Multiple heat abstractors, such as louvre and radiating groove, and locating dowel is also adopted by thermal grease post so that having of multilayer circuit board is good
Good radiating effect.
