| titleOfInvention | A kind of fireproof circuit board device |
| abstract | The utility model discloses a kind of fireproof circuit board device, comprise circuit board section and fire-resistant parts, described circuit board section is by the first wiring layer, sandwich layer, second wiring layer forms with plating hole, on the upper surface that described first wiring layer and the second wiring layer are arranged in sandwich layer and lower surface, first wiring layer and the second wiring layer are connected by the through sandwich layer of described plating hole, described fire-resistant parts is fireproof glass steel tank box, described fireproof glass steel tank box is by the first wiring layer, sandwich layer, second wiring layer is placed in its inside with plating hole, compared with prior art, the utility model contains by sandwich layer being replaced by flame-proof cover copper foil modification bonding sheet material the possibility that circuit board is on fire, 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. |
