Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic packaging shell technology, and in particular to a zero-defect bonding and printing fixture for ceramic structural components. Background Technology
[0002] In the manufacturing of ceramic packaging shells (such as semiconductor and sensor packaging), high-viscosity colloids are used for printing multilayer ceramic circuits and bonding structural components. For example, conductive adhesives (such as silver-containing epoxy resin) are printed onto green ceramic sheets using thick-film screen printing technology to form circuit patterns. Subsequently, lamination and sintering are used to achieve interlayer bonding and circuit integration. Currently, conventional printing fixtures have significant drawbacks in practical applications: due to the extremely high viscosity of the colloid, adhesive residue is prone to occur during printing, preventing the colloid from being uniformly transferred to the substrate surface. Furthermore, traditional fixtures struggle to control the flowability and distribution of the colloid, resulting in uneven adhesive layer thickness and noticeable edge burrs after printing. This defect not only affects the consistency of the product's appearance but also leads to voids or stress concentration points at the bonding interface, directly impacting the phase accuracy and long-term reliability of the structural components.
[0003] Chinese utility model publication number CN204361130U discloses a fixture for arranging and bonding flow guides. This patent is used to directly attach multiple flow guides to a ceramic substrate, and is unrelated to the bonding of structural components of multilayer ceramic circuits. Utility Model Content
[0004] The technical problem to be solved by this invention is that existing printing fixtures for ceramic structural parts are difficult to control the flowability and distribution of the colloid. To address this, a zero-defect bonding printing fixture for ceramic structural parts is provided.
[0005] The technical solution of this utility model is as follows: a zero-defect bonding and printing fixture for ceramic structural parts, comprising: a rectangular base; multiple strip slots, wherein the multiple strip slots are opened parallel and spaced apart on the surface of the rectangular base; and ventilation holes, wherein the ventilation holes are opened at the bottom of each strip slot.
[0006] An improvement to the above solution is that the rectangular base has inwardly recessed handrail grooves on both sides.
[0007] In the above scheme, one end of each of the strip slots is open and flush with the edge of the rectangular base, while the other end is a blind end.
[0008] In the above scheme, there are multiple ventilation holes in each strip slot and they are distributed at intervals along the length of the strip slot.
[0009] A further improvement to the above solution is that the surface of the armrest groove is provided with anti-slip texture.
[0010] The rectangular base described in the above scheme is made of anodized aluminum alloy.
[0011] The beneficial effects of this invention are that multiple strip-shaped slots are used to fix the product, facilitating subsequent glue application and adapting to the gluing of multiple batches of structural parts. Initial positioning is achieved through physical limiting, avoiding manual placement deviations. Ventilation holes are passed through the bottom of the strip-shaped slots, creating negative pressure adsorption after placing an exhaust fan, ensuring that the workpiece remains completely immobile during printing. This design is particularly suitable for resisting shear forces during high-viscosity colloid printing, fundamentally preventing rheological changes or uneven thickness caused by workpiece movement. The handle slot facilitates operation and movement. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] like Figure 1-2 As shown, a zero-defect bonding and printing fixture for ceramic structural parts includes: a rectangular base 1; multiple strip slots 2, which are parallel and spaced apart on the surface of the rectangular base, each strip slot being used to place a workpiece to be bonded, one end of each strip slot being open and flush with the edge of the rectangular base, and the other end being a blind end, or both ends of the multiple strip slots being open and flush with the edge of the rectangular base, or both ends of the multiple strip slots being blind ends; ventilation holes 3, which are formed at the bottom of each strip slot, and each strip slot may have multiple ventilation holes, such as 4, 5 or 3, etc., which are spaced apart along the length of the strip slot.
[0017] As a preferred embodiment of this utility model, the rectangular base is provided with inwardly recessed handrail grooves 4 on both sides. The handrail grooves are ergonomically designed to support single-handed gripping and two-handed operation. Actual test data shows that workpiece handling and positioning time is reduced by more than 50%, and operator fatigue is reduced by 40%, making it particularly suitable for high-frequency operations on continuous production lines.
[0018] As a preferred embodiment of this utility model, the surface of the handrail groove is provided with anti-slip texture. The rectangular base is made of anodized aluminum alloy. This improves handling stability while preventing slippage or collision damage during workpiece handling.
[0019] The process is as follows: The workpiece is placed in the strip slot and connected to the ventilation hole via an external negative pressure device for vacuum adsorption and fixation. A quantitative amount of adhesive is applied to the workpiece. It is then molded in one pass using a scraper. Through physical positioning and vacuum fixation, the adhesive layer thickness fluctuation rate is reduced from ±15% in traditional processes to ±3%, and the product yield is increased to over 99.5%. The results are shown in the table below.
