The beneficial effects of the utility model: a kind of fireproof circuit board device of the present utility model, the possibility that circuit board is on fire is contained by sandwich layer being replaced by flame-proof cover copper foil modification bonding sheet material, the thermal coefficient of expansion of circuit board in in-plane is not more than 20ppm/ DEG C and solves the phenomenon causing short circuit because the coefficient of expansion is excessive under laminated arrangement, the interpolation of fireproof glass steel tank box then can make outside fire suffer from and cannot impact circuit board, the problem proposed in above-mentioned background technology is solved by the method, the utility model is easy to use, structure is simple, innovation is novel.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of a kind of fireproof circuit board device of the utility model;
Fig. 2 is the structural representation of a kind of fireproof circuit board device of the utility model;
In figure: 1-first wiring layer, 2-sandwich layer, 3-second wiring layer, 4-fireproof glass steel tank box, 5-electroplate hole, 6-circuit board.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
Refer to Fig. 1 and Fig. 2, the utility model provides a kind of technical scheme: comprise circuit board 6 part and fire-resistant parts, circuit board 6 part is by the first wiring layer 1, sandwich layer 2, second wiring layer 3 forms with plating hole 5, on the upper surface that first wiring layer 1 and the second wiring layer 3 are arranged in sandwich layer 2 and lower surface, first wiring layer 1 and the second wiring layer 3 are connected by the through sandwich layer 2 of plating hole 5, the connection of the first wiring layer 1 and the second wiring layer 3 is realized by plating hole 5, fire-resistant parts is fireproof glass steel tank box 4, fireproof glass steel tank box 4 is by the first wiring layer 1, sandwich layer 2, second wiring layer 3 is placed in its inside with plating hole 5, effectively prevent the impact of outside fire trouble on circuit board, the thickness of the first wiring layer 1 and the second wiring layer 3 is 0.5mm, and be arranged on sandwich layer 2 by the mode printed, the thickness of sandwich layer 2 is 1mm, and sandwich layer 2 is made up of flame-proof cover copper foil modification bonding sheet material, the thermal coefficient of expansion of circuit board 6 in in-plane is not more than 20ppm/ DEG C under laminated arrangement, prevent the situation causing circuit board 6 short circuit because thermal coefficient of expansion is excessive from occurring, plating hole 5 is coated with metallic copper, fireproof glass steel tank box 4 material is fiberglass reinforced plastics, be specially a cube tray box, can conveniently lay circuit board 6.
Concrete occupation mode: when outside breaking out of fire, naked light can intercept at it outside by fireproof glass steel tank box 4, make naked light cannot cause to circuit board 6 loss that cannot retrieve, meanwhile, due to the effect of naked light, temperature in fireproof glass steel tank box 4 can start to raise, because sandwich layer 2 is made up of flame-proof cover copper foil modification bonding sheet material, therefore sandwich layer 2 can not the spontaneous combustion because temperature is too high, the thermal coefficient of expansion of circuit board 6 in in-plane is not more than 20ppm/ DEG C under laminated arrangement, so the rising of temperature there will not be because thermal coefficient of expansion is excessive and cause the situation of circuit board 6 short circuit.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model, to those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, the utility model can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
