Method for simultaneously sintering two layers of copper-clad ceramic substrate
The invention discloses a method for simultaneously sintering double layers of a copper-clad ceramic substrate, relates to the field of copper-clad ceramic substrate processing, and aims to solve the problem of low efficiency caused by single-layer sintering at present. The method is characterized in that a lower-layer silicon carbide sintering jig is firstly placed on a sintering furnace material preparation table, and a ceramic chip and a copper sheet are placed in the lower-layer silicon carbide sintering jig; the upper surface of the edge of the silicon carbide jig is provided with at least two protrusions, and the positions, corresponding to the protrusions, of the lower surface of the edge of the silicon carbide jig are provided with grooves; when the two layers of silicon carbide jigs are stacked, the bulges of the silicon carbide jig on the lower layer are clamped in the grooves of the silicon carbide jig on the upper layer; then the top is covered with a ceramic cover plate; every two adjacent jigs are tightly attached, a specific sintering curve is used, and the product and the jigs are subjected to the stages of heating, heat preservation and cooling in a hearth; and collecting the material. According to the method for simultaneously sintering the double layers of the copper-clad ceramic substrate, the double layers can be simultaneously sintered, the sintering efficiency is high, and energy is saved.
本发明公开了一种覆铜陶瓷基板双层同时烧结的方法，涉及覆铜陶瓷基板加工领域，旨在解决目前只能单层烧结效率低的问题，其技术方案要点是：在烧结炉备料台上先摆放下层碳化硅烧结治具，内部放置瓷片、铜片；然后在治具上再放置上层的碳化硅治具，碳化硅治具在其边缘上表面至少具有两个凸起，其边缘下表面对应凸起的地方具有凹槽；当两层碳化硅治具叠放时，下层的碳化硅治具的凸起卡在上层碳化硅治具的凹槽内；然后在顶部再盖上陶瓷盖板；每相邻的治具紧密贴合，使用特定的烧结曲线，产品、治具在炉膛中经历升温，保温，降温阶段；收料。本发明的一种覆铜陶瓷基板双层同时烧结的方法能够双层同时烧结，烧结效率高，节约能源。
