The invention discloses a lining for an electronic material sintering furnace plate. The lining comprises a lining body. A general structure of the lining body is rectangular. Chamfering is conducted on the four corners of a rectangular substrate. Four positioning holes are formed in the lining body. A cutting opening is formed in the edge of the lining body. Multiple clamping grooves are formed in the end face relatively located at the bottom of the cutting opening. The clamping grooves are formed at intervals in a step shape. A jacket is arranged on the position, on the cutting opening position, of the lining body. The lining is simple in the structure and capable of being suitable for clamping operations of furnace plates of different specifications, and the universality is good; and the jacket is additionally arranged, the connecting firmness of the furnace plate and the lining is improved remarkably, and the lining is convenient to use and practical.
