Abstract
Description
Technical Field
[0001] The utility model relates to the field of ceramic substrate technology, in particular to a 3D metal dam ceramic frame structure. Background Art
[0002] Based on the thin film circuit process, the ceramic surface is metallized by magnetron sputtering, and the copper layer thickness is greater than 10 microns by electroplating. That is DPC (Direct Plate Copper). The thin film method is the main method for metal film deposition in microelectronics manufacturing, among which direct copper plating is the most representative. Direct copper plating (DPC) mainly uses surface deposition processes such as evaporation and magnetron sputtering to metallize the substrate surface. First, titanium is sputtered under vacuum conditions, then copper particles, and finally electroplating thickening. Then the circuit is completed by ordinary PCB process, and finally the thickness of the circuit is increased by electroplating / chemical plating deposition. The preparation method of DPC includes vacuum coating, wet coating, exposure and development, etching and other process links, so the price of its products is relatively high. The DPC process is suitable for most ceramic substrates.
[0003] In order to facilitate chip packaging, a 3D metal dam is usually formed on the surface periphery of the ceramic substrate through multiple thickening and electroplating. Since the ceramic substrate is used in various products, different products have different models, dam thicknesses, and the number of dam electroplating times. Therefore, when the dam is completed, it is necessary to distinguish them. In the prior art, the main method is to stick labels on the ceramic substrate. However, the label is easy to fall off and cannot play a role in identification. In addition, the label is easy to have an adverse effect on the function of the ceramic substrate and also affects the appearance of the ceramic substrate. Therefore, it is necessary to study a solution to solve the above problems. Utility Model Content
[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a 3D metal dam ceramic frame structure, which can effectively solve the problem of the existing method of using labels to distinguish ceramic substrates, such as labels are easy to fall off, causing adverse effects on the functions of the ceramic substrates, and also affecting the appearance of the ceramic substrates.

[0007] As a preferred solution, the ceramic frame body is square, which is formed by connecting four sides end to end. The model marking area, dam thickness marking area and dam number marking area are respectively located on different sides to facilitate manufacturing and differentiation.
[0008] As a preferred solution, the model marking area, dam thickness marking area and dam number marking area are all located on the inner side of the 3D metal dam to better protect the model marking layer, dam thickness marking layer and dam number marking layer, avoid the model marking layer, dam thickness marking layer and dam number marking layer from being easily damaged, and at the same time will not cause any impact on the appearance of the product.
[0009] As a preferred solution, the 3D metal dam is made of copper-plated material, which is formed through multiple electroplating processes and has a stable structure.

[0011] As a preferred solution, the 3D metal dam is provided with alignment points for alignment installation with the outside.
[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:
