Description

A kind of multilayer circuit board of Anti-seismic
Technical field
The utility model is related to circuit board technology fields, and in particular to a kind of multilayer circuit board of Anti-seismic.
Background technology
Circuit board has already taken up consequence in the electronics industry.Nearly ten years, circuit board fabrication industry in China's is sent out Exhibition is rapid, and lamina cannot be satisfied with present diversified electronic equipment, and multilayer circuit board is close due to integrated antenna package The increase of degree results in the high concentration of interconnection line, this makes the use of more substrates become required.In the space of a whole page cloth of printed circuit In office, there is unpredictalbe design problem, such as noise, stray capacitance, crosstalk.So Printed Circuit Board Design is necessary It efforts be made so that signal line length is minimum and avoids parallel line etc..Obviously, in single sided board, even in dual platen, due to The number of crossovers that may be implemented is limited, these demands cannot all obtain satisfied answer.In the feelings of a large amount of interconnection and intersection demand Under condition, as soon as circuit board will reach a satisfied performance, plate layer must be expanded to two layers or more, thus multilayer circuit occur Plate.
Existing multilayer circuit board is made of stacked multi-layer board, and anti-seismic performance is poor, when multilayer circuit board application In mobile devices such as unmanned plane, automobiles, multilayer circuit board is easy to damage because of the high-speed motion of mobile device.
Utility model content
In view of the above problems, the utility model provides a kind of multilayer circuit board of good seismic performance.
To achieve the above object, the utility model solves by the following technical programs:
A kind of multilayer circuit board of Anti-seismic, including circuit board, the circuit board include stack gradually from top to bottom it is upper Laminate, the first clathrum, double-sided substrate, the second clathrum, lower plywood, the circuit board are interior equipped with several perforative from top to bottom Via, first clathrum are made of several strip epoxy resin to intersect vertically, are formed in first clathrum several First through hole, second clathrum are made of several strip silica gel plates to intersect vertically, if being formed in second clathrum Dry second through-hole, the via both pass through the first through hole and second through-hole.
Specifically, the thickness of first clathrum is 0.3mm.
Specifically, the thickness of second clathrum is 0.5mm.
Specifically, the top plate upper surface is equipped with several electronic components.
Specifically, the double-sided substrate upper and lower surface is equipped with several conducting wires, the conducting wire passes through the mistake The double-sided substrate is electrically connected by hole with the top plate, the lower plywood.
Specifically, the lower plywood lower surface is equipped with several pads.
The utility model has the beneficial effects that:
Multilayer circuit board uses latticed respectively between top plate and double-sided substrate, between double-sided substrate and lower plywood Plate layer and the prepreg instead of device of shifting block type, latticed plate layer form multiple through-holes, enhance the gas permeability of circuit board; On the other hand, the second clathrum is made of several strip silica gel plates to intersect vertically, and silica gel plate has high resiliency, can enhance circuit The anti-seismic performance of plate.
