| titleOfInvention | A kind of aluminium nitride ceramics circuit board and preparation method |
| abstract | The present invention relates to a kind of aluminium nitride ceramics circuit board and preparation method, aluminium nitride ceramics circuit board includes: the ceramic substrate that surface is covered with laser sintered metal conducting layer, and the circuit prepared using chemical etching method.Its aluminium nitride ceramics circuit board preparation method, comprising: according to aluminium nitride ceramics chip size, draw out and need metallized area；Laser sintered to alumimium nitride ceramic sheet progress, laser scanning terminates, and alumimium nitride ceramic sheet surface is all metallized；Chemical etching is carried out to aluminium nitride copper-clad plate, finally obtains circuit board；Foregoing circuit plate is polished, heat cure is carried out after character silk printing.Without containing low thermally conductive, the insulating glass phase contained by traditional metallization method between ceramic substrate of the invention and metal conducting layer, to ensure that the thermal conductivity of ceramic circuit board and the electric conductivity of metal layer. |
