Composite burning board provided with positioning grooves on double surfaces and used for roasting electronic materials

Abstract

A composite burning board provided with positioning grooves on double surfaces and used for roasting electronic materials belongs to the technical field of kilns and comprises various composite burning board layers which are stacked. The positioning grooves are respectively arranged on front and reverse surfaces of four corners of a rectangular body of each composite burning board layer, the upper and lower composite burning board layers are stacked by means of fittingly connecting positioning pins with the positioning grooves, a supporting effect is realized, and furthermore, when a kiln operates unstably, the burning board layers in the operation direction of the kiln and the side perpendicular direction can be positioned in a controlled manner.

Description

technical field [0001] The invention belongs to the technical field of kiln furniture, and in particular relates to a composite setter with double-sided positioning grooves for firing electronic materials. Background technique [0002] Domestic kilns for producing electronic materials are mainly high-temperature kilns, which have high technical requirements on the thermal shock resistance of the setters on which the products are placed. Currently, flat setters are often used, and the setters of each layer are The square supports are laid, and the volume is large, which affects the firing effect, especially when in use, because the kiln furniture combination moves in a step-by-step manner in the kiln, and the kiln furniture combination is alternately cycled between static and moving conditions, and there will be abnormalities between the kiln furniture Shaking or slight movement will cause the support to shift, affecting the stability of the setter plate. In severe cases, the...
