Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging shell technology, and in particular to a high-strength corrosion-resistant ceramic packaging shell. Background Technology
[0002] Ceramic encapsulation housing is a type of encapsulation housing that is widely used in the packaging of various integrated circuits (ICs).
[0003] The main body of a ceramic package typically consists of a bottom package and a top package. First, the electronic components to be packaged are placed into the bottom package, and then the bottom package and the top package are soldered together using a brazing method.
[0004] Currently, the existing ceramic packaging shells generally adopt a rectangular structure for the bottom shell and top cover. When the inner cavity is subjected to external extrusion, deformation will occur, which greatly reduces the overall resistance to external extrusion and deformation of the bottom shell and top cover of the ceramic packaging shell.
[0005] Moreover, the existing ceramic packaging shell body has weak resistance to external puncture, which reduces the overall resistance of the bottom and top covers of the ceramic packaging shell body to external puncture.
[0006] In addition, the outer walls of the existing ceramic encapsulation shell body, including the bottom shell and the top cover, have relatively weak corrosion resistance. Utility Model Content
[0007] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a high-strength, corrosion-resistant ceramic encapsulation shell.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] Design a high-strength, corrosion-resistant ceramic encapsulation shell, comprising a ceramic encapsulation shell body, the ceramic encapsulation shell body being composed of a bottom encapsulation shell and a top encapsulation shell, the bottom encapsulation shell having pins and a bottom solder surface, the top encapsulation shell having a top solder surface, the bottom encapsulation shell having a reinforcing bend plate, the reinforcing bend plate having a reinforcing slot having a main adhesive layer inside the reinforcing slot, the top encapsulation shell having a reinforcing post, the reinforcing post having a supporting rib plate, and the supporting rib plate having a secondary adhesive layer;
[0010] Both the bottom and top covers of the package are provided with puncture-resistant inner layers.
[0011] Both the bottom and top covers of the package are provided with corrosion-resistant and heat-dissipating layers.
[0012] Furthermore, the reinforcing bend plate is a triangular structure, and there are four reinforcing bend plates, which are respectively set at the four inner corners of the packaging bottom shell. The bottom of the reinforcing bend plate is tightly fixed to the inner wall of the packaging bottom shell.
[0013] Furthermore, the reinforcing slots and reinforcing pins are arranged as a group, with a total of four symmetrically arranged groups, and the reinforcing slots and reinforcing pins are matched and plugged in.
[0014] Furthermore, the main adhesive layer is evenly applied along the reinforcing slot and tightly adheres to the outer wall surface of the reinforcing post.
[0015] Furthermore, the supporting ribs are generally triangular in shape and consist of four circumferentially arranged ribs, and the secondary adhesive layer is located on the lower end face of the supporting ribs.
[0016] Furthermore, the puncture-resistant inner layer is respectively disposed in the bottom outer shell and the top cover of the package, and the puncture-resistant inner layer is an aluminum nitride structural layer with a thickness of one hundred to one hundred and twenty micrometers.
[0017] Furthermore, the anti-corrosion heat dissipation layer is uniformly coated along the outer wall surfaces of the bottom and top covers of the package, and the anti-corrosion heat dissipation layer is a graphene coating with a thickness of fifteen to twenty micrometers.
[0018] The high-strength, corrosion-resistant ceramic encapsulation shell proposed in this utility model has the following advantages:
[0019] 1. This utility model improves the overall resistance to external extrusion and deformation of the ceramic packaging shell body by setting a reinforcing bend plate with a reinforcing slot on the bottom shell of the packaging and setting a main adhesive layer in the reinforcing slot, and then setting a reinforcing post with a supporting rib on the top cover of the packaging, and then setting a secondary adhesive layer on the supporting rib. After the bottom shell of the packaging and the top cover of the packaging are welded and packaged, the overall resistance to external extrusion and deformation of the bottom shell of the packaging and the top cover of the packaging are improved.
[0020] 2. This utility model improves the overall puncture resistance of the ceramic packaging shell body to the outside by setting puncture-resistant inner layer structures on both the bottom and top shells of the packaging.
[0021] 3. This utility model improves the corrosion resistance of the outer walls of both the bottom and top covers of the package by providing anti-corrosion and heat dissipation layers. Attached Figure Description

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Reference Figure 1-6 A high-strength, corrosion-resistant ceramic encapsulation shell includes a ceramic encapsulation shell body 10, which is composed of a bottom encapsulation shell 1 and a top encapsulation cover 2. The bottom encapsulation shell 1 is provided with pins 11 and a bottom solder surface 12. The top encapsulation cover 2 is provided with a top solder surface 21. The bottom encapsulation shell 1 is provided with a reinforcing bend plate 4. The reinforcing bend plate 4 has a reinforcing slot 41. The reinforcing slot 41 has a main adhesive layer 42. The top encapsulation cover 2 is provided with a reinforcing post 5. The reinforcing post 5 has a supporting rib plate 6. The supporting rib plate 6 has a secondary adhesive layer 61.
[0031] Both the bottom outer shell 1 and the top cover 2 of the package are provided with a puncture-resistant inner layer 7;
[0032] Both the bottom outer shell 1 and the top cover 2 of the encapsulation are provided with an anti-corrosion heat dissipation layer 3. Some of the structures described in this patent are common structures of ceramic encapsulation shells and are existing technologies. Some existing structures are not drawn or marked and need not be described in detail.
[0033] The reinforcing bend plate 4 has a triangular structure. There are four reinforcing bend plates 4, which are respectively set at the four inner corners of the packaging bottom shell 1. The bottom of the reinforcing bend plate 4 is tightly fixed to the bottom wall of the inner cavity of the packaging bottom shell 1. The reinforcing bend plate 4 is made of hard plastic steel, which is insulated and has high strength, greatly improving the deformation resistance of the four inner corners of the packaging bottom shell 1.
[0034] The reinforcing slots 41 and reinforcing posts 5 are a set, and there are four sets symmetrically arranged in total. The reinforcing slots 41 and reinforcing posts 5 are matched and plugged in. The reinforcing posts 5 are made of hard plastic steel, which is insulated and has high strength, so as to achieve stable support for the entire encapsulation top cover 2, thereby improving the overall structural strength of the ceramic encapsulation shell body 10.
[0035] The main adhesive layer 42 is evenly applied along the reinforcing slot 41 and tightly adheres to the outer wall of the reinforcing post 5, thereby achieving a comprehensive and stable bond to the bottom and outer wall of the reinforcing post 5 inserted into the reinforcing slot 41.
[0036] The supporting rib plate 6 is a triangular structure with four circumferentially arranged. The supporting rib plate 6 is made of rigid plastic steel, which is insulated, has high strength, and does not deform. Combined with the triangular structure, it improves the overall structural stability of the reinforcing column 5.
[0037] The secondary adhesive layer 61 is located on the lower end face of the supporting rib plate 6. Both the secondary adhesive layer 61 and the main adhesive layer 42 are made of epoxy resin adhesive, which has excellent adhesion, high temperature resistance and durability.
[0038] The puncture-resistant inner layer 7 is respectively disposed in the bottom outer shell 1 and the top cover 2 of the package. The puncture-resistant inner layer 7 is an aluminum nitride structure layer with a thickness of 100 to 120 micrometers. The aluminum nitride structure layer has excellent puncture resistance, high thermal conductivity and low coefficient of thermal expansion, and extremely high mechanical strength and hardness, while ensuring overall heat dissipation.
[0039] The anti-corrosion heat dissipation layer 3 is uniformly coated along the outer wall surfaces of the bottom shell 1 and the top cover 2 of the package. The anti-corrosion heat dissipation layer 3 is a graphene coating with a thickness of 15 to 20 micrometers. The graphene coating itself has excellent anti-corrosion and heat dissipation performance, high temperature resistance and durability, which improves the corrosion resistance of the outer wall surface of the ceramic package shell 10 as a whole, while ensuring the overall heat dissipation.
[0040] Working method: The bottom shell 1 and the top cover 2 of the package are packaged and welded by brazing through the bottom welding surface 12 and the top welding surface 21 (existing technology). After the package is welded, each reinforcing post 5 will be inserted into the matching reinforcing slot 41. After the main adhesive layer 42 solidifies, the reinforcing post 5 and the reinforcing slot 41 can be firmly bonded. At the same time, the lower end of the supporting rib 6 will be in close contact with the upper end of the reinforcing bend 4. After the secondary adhesive layer 61 solidifies, the lower end of the supporting rib 6 and the upper end of the reinforcing bend 4 can be firmly bonded. The combination of the reinforcing bend 4 and the supporting rib 6 to stabilize and enhance the deformation resistance, and the overall insertion and support of the reinforcing post 5 to enhance stability, improves the overall resistance to external extrusion and deformation of the bottom shell 1 and the top cover 2 of the ceramic package body 10.
[0041] Furthermore, by providing puncture-resistant inner layer 7 structures on both the bottom outer shell 1 and the top cover 2 of the ceramic encapsulation shell body 10, the overall puncture resistance of the bottom outer shell 1 and the top cover 2 of the ceramic encapsulation shell body 10 to the outside is improved.
[0042] In addition, by providing anti-corrosion heat dissipation layers 3 on the outer walls of both the bottom casing 1 and the top cover 2, the overall corrosion resistance of the outer walls of the bottom casing 1 and the top cover 2 is improved.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
