Description

A ceramic plate slag scraper Technical Field

[0001] This utility model relates to the technology in the field of ceramic plate production, and in particular to a ceramic plate slag scraping fixture. Background Technology

[0002] Ceramic substrates for packaging generally refer to substrates or packages made of ceramic materials in the field of electronic packaging. Due to their unique physical, chemical, and electrical properties, these ceramic substrates are widely used in high-end electronic packaging. Ceramic packaging materials possess characteristics such as high thermal conductivity, high mechanical strength, high chemical stability, good insulation, and excellent thermal matching. These properties enable ceramic packaging to maintain stable performance in harsh environments such as high frequency, high power, and high temperature, thus making it widely used in the packaging of high-end electronic products such as integrated circuits, power devices, and sensors. During the packaging process, the ceramic substrate typically acts as a bridge between the chip and the external environment, providing support, protection, and connection. It effectively conducts heat generated by the chip, preventing overheating damage; simultaneously, the high mechanical strength of the ceramic substrate provides sufficient protection for the chip, preventing it from being affected by external impacts and vibrations.

[0003] Drilling is an essential step in the production of ceramic tessellation plates. During drilling, burrs (debris) often remain on the sides of the through-hole opening. These burrs need to be removed after drilling. Current technology primarily involves scraping the burrs off the ceramic tessel on a platform. However, this method easily allows burrs to fall into the through-hole, causing blockage. Subsequent copper plating of the through-hole can result in poor resistance or even open circuits, leading to electrical malfunctions. Therefore, it is necessary to research a solution to address these problems. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a ceramic plate scraping fixture, which can effectively solve the problem that the residue of the ceramic plate easily falls into the through hole after scraping, resulting in poor electrical properties.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ceramic plate scraping fixture includes a fixture body. The top surface of the fixture body is a bearing plane for supporting and placing ceramic plates. The bearing plane is recessed with multiple air blowing chambers and multiple adsorption holes. The multiple adsorption holes are distributed on the sides of the multiple air blowing chambers. The fixture body is provided with an air inlet chamber and an air extraction channel. The multiple air blowing chambers are all connected to the air inlet chamber, and the multiple adsorption holes are all connected to the air extraction channel. An air inlet and an air extraction port are opened on the side of the fixture body. The air inlet is connected to the air inlet chamber, and the air extraction port is connected to the air extraction channel.

[0007] As a preferred embodiment, the fixture body includes a main seat and a bottom cover. The bearing plane is located on the top surface of the main seat, and the bottom cover is located at the bottom of the main seat and forms an air intake chamber with the main seat. The structure is simple and easy to manufacture.

[0008] As a preferred embodiment, the multiple air-blowing chambers are arranged in an array for better air blowing.

[0009] As a preferred embodiment, the air extraction channels are multiple interconnected and crisscrossed, which facilitates better adsorption.

[0010] As a preferred embodiment, the air inlet is located at the front center of the main seat, and the air outlet is located at the left center of the main seat, so as to ensure uniform air pressure distribution.

[0011] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0012] By utilizing the suction port, suction channel, and multiple adsorption holes, the ceramic plate is firmly adsorbed and fixed on the bearing surface. Furthermore, by utilizing the air inlet, air inlet chamber, and multiple blowing chambers, airflow is output from each through hole of the ceramic plate. During the slag scraping process of the ceramic plate, the airflow can effectively prevent residue from falling into the through holes, fundamentally solving the problem of residue / burr entering the holes, eliminating the occurrence of hole blockage, and ensuring that the through holes are filled during subsequent copper plating, so that the resistance value will not be poor or even open circuit, achieving excellent electrical properties.

[0027] Please refer to Figures 1 to 5, which show the specific structure of a preferred embodiment of the present invention, including a fixture body 10.

[0028] The top surface of the fixture body 10 is a bearing plane 101 for supporting and placing the ceramic plate 20. The bearing plane 101 is recessed with multiple air blowing chambers 102 and multiple adsorption holes 103. The multiple adsorption holes 103 are distributed on the sides of the multiple air blowing chambers 102. The fixture body 10 is provided with an air inlet chamber 104 and an air extraction channel 105. The multiple air blowing chambers 102 are all connected to the air inlet chamber 104, and the multiple adsorption holes 103 are all connected to the air extraction channel 105. The side of the fixture body 10 is provided with an air inlet 106 and an air extraction port 107. The air inlet 106 is connected to the air inlet chamber 104, and the air extraction port 107 is connected to the air extraction channel 105.

[0029] Specifically, the fixture body 10 has a square structure and includes a main seat 11 and a bottom cover 12. The bearing plane 101 is located on the top surface of the main seat 11, and the bottom cover 12 is located on the bottom of the main seat 11, forming an air intake chamber 104 together with the main seat 11. In this embodiment, the plurality of air blowing chambers 102 are arranged in an array. The air extraction channels 105 are multiple crisscrossed and interconnected. Furthermore, the air inlet 106 is located at the front center of the main seat 11, and the air extraction port 107 is located at the left center of the main seat 11.

[0030] The usage method of this embodiment is described in detail below:

[0031] First, connect the air inlet 106 to the air supply device and the air extraction port 10 to the air extraction device. Next, place the ceramic plate 20 to be scraped on the bearing plane 101. The ceramic plate 20 is integrally formed from multiple substrate units 21. Each substrate unit 21 has multiple through holes 201. Each substrate unit 21 is located directly above the corresponding blowing chamber 102. Then, the air extraction device extracts air from the air extraction channel 105, so that multiple adsorption holes 103 form a negative pressure to firmly adsorb and fix the ceramic plate 20 to be scraped on the bearing plane 101. Next, start the air supply device. The airflow enters the air intake chamber 104 from the air inlet 106 and then enters each blowing chamber 102. Finally, the airflow exits from each through hole 201 of the ceramic plate 20. At this time, the ceramic plate 20 can be scraped. The airflow prevents the residue from falling into the through holes 201, fundamentally solving the problem of residue / burrs entering the holes. During the slag scraping process, the suction pressure is much greater than the supply pressure to ensure that the ceramic plate 20 is firmly fixed on the bearing surface 101. After the slag scraping operation is completed, the air supply device and the suction device are stopped. The ceramic plate 20 is no longer adsorbed and fixed, and it can then be removed from the bearing surface 101.

[0032] The key design feature of this invention is that by utilizing an air extraction port, an air extraction channel, and multiple adsorption holes, the ceramic plate is firmly adsorbed and fixed on the supporting surface. Furthermore, by utilizing an air inlet, an air inlet chamber, and multiple blowing chambers, airflow is output from various through holes in the ceramic plate. During the slag scraping process, the airflow can effectively prevent residue from falling into the through holes, fundamentally solving the problem of residue / burrs entering the holes, eliminating the occurrence of hole blockage, and ensuring that the through holes are filled during subsequent copper plating, so that the resistance value will not be poor or even open circuit, achieving excellent electrical properties.

[0033] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
