Abstract

The invention discloses a breathable sagger for roasting of electronic materials. The breathable sagger for roasting of electronic materials comprises a sagger body, wherein the sagger body is formedby a sagger bottom and four sagger walls in a surrounding manner; the sagger bottom is a flat bottom or is provided with supporting legs; a recessed ventilating opening is formed in the top of each sagger wall; and small through holes are formed in the sagger bottom. Compared with the prior art, the breathable sagger for roasting of the electronic materials can be uniformly heated, good convectioneffect of an internal atmosphere and an external atmosphere of the sagger is ensured, sintering of the electronic materials is facilitated, and the superior product rate of electronic material products is increased.

Description

technical field

[0001] The invention belongs to the technical field of kiln furniture, and in particular relates to a gas-permeable sagger for roasting electronic materials. Background technique

[0002] Electronic components and electronic materials are the foundation of the electronic information industry. They mainly rely on high-temperature kilns for firing. Saggers are the main loading tools for firing electronic components and electronic materials. Electronic materials have high requirements on the performance of kiln furniture, and the firing atmosphere is not uniform. It will have a serious impact on the performance of electronic components and electronic materials. During sintering, although the atmosphere of the leg-shaped saggar is significantly improved compared with the atmosphere of the flat-bottomed saggar, the influence of the convection of the external atmosphere on the firing of electronic materials in the sagger is limited. Contents of the invention [...

Examples

Embodiment 1

[0013] Example 1, such as Figure 1~2 As shown, a gas-permeable sagger for roasting electronic materials includes a sagger body 1, which is surrounded by a sag bottom and walls on four sides. The air vent 2 is sunken, and a transparent small hole 3 is provided on the bottom of the box.

Embodiment 2

[0014] Embodiment 2, with reference to Example 1, a vent is provided on the four walls of the sagger body, the cross section of the vent is preferably an isosceles trapezoid, and the length of the vent accounts for 20-90% of the side length of the sagger, The depth accounts for 5%-75% of the height of the box wall, the diameter of the transparent small hole is 0.8-5mm, and the height of the supporting feet is 1-50mm.
