Description

Technical Field

[0001] This utility model relates to the field of chip packaging technology, and in particular to a special electrode for through-hole caps. Background Technology

[0002] In existing chip packaging processes, the cap is usually designed with a flat window or a ball window structure to facilitate stable packaging of the electrode system through negative pressure adsorption.

[0003] However, in certain specialized applications, the cap has a through-hole structure without a flat or spherical window design. This structure prevents the conventional upper electrode from forming an effective closed space, resulting in a significant loss of negative pressure adsorption force, which in turn affects the positioning accuracy and packaging stability of the cap. Utility Model Content

[0004] The purpose of this invention is to provide a special electrode for through-hole caps, which solves the problem that in some special application scenarios, the caps are through-hole structures without flat windows or ball windows, which makes it impossible for conventional upper electrodes to form an effective closed space, resulting in significant loss of negative pressure adsorption force and affecting the positioning accuracy and packaging stability of the caps.

[0005] To achieve the above objectives, this utility model provides a special electrode for through-hole pipe caps. The special electrode for through-hole pipe caps includes an upper electrode body, a sliding core, a venting pressure ring, and a spring. The upper electrode body has an encapsulation area inside, which is arranged in a three-section stepped structure that is narrower at the top and wider at the bottom. The encapsulation area consists of a first encapsulation area, a second encapsulation area, and a third encapsulation area from top to bottom. The sliding core is installed inside the encapsulation area, and the venting pressure ring is installed inside the third encapsulation area. The bottom of the sliding core is slidably connected to the venting pressure ring, and the spring is arranged between the upper surface of the venting pressure ring and the top of the sliding core.

[0006] The top of the sliding core is fixedly provided with a gas-blocking ring, and the upper surface of the gas-blocking ring is fixedly provided with a protrusion. The protrusion is in clearance fit with the first packaging area, and the gas-blocking ring is in clearance fit with the second packaging area. The diameter of the gas-blocking ring is larger than the diameter of the first packaging area.

[0007] The upper surface of the venting pressure ring is also provided with a washer, which is located on the outside of the bottom end of the spring.

[0008] The ventilation ring has a sliding hole at its center, and the bottom end of the sliding core is fitted with the sliding hole with a clearance.

[0009] The venting ring is provided with multiple vent holes, which are evenly arranged around the sliding hole.

[0010] This utility model discloses a special electrode for through-hole caps, comprising an upper electrode body, a sliding core, a venting pressure ring, and a spring. The through-hole cap is fed into the encapsulation area of ​​the upper electrode body, with the upper end of the through-hole cap contacting the bottom of the sliding core. The encapsulation area forms a closed negative pressure adsorption space, and the venting pressure ring allows gas to escape, maintaining sufficient negative pressure. Under the action of negative pressure suction, the through-hole cap and the sliding core contract upwards until they reach the raised edge of the through-hole cap, thereby achieving precise positioning of the through-hole cap and meeting the capping requirements. By adopting the above structure, the problem of through-hole caps being unable to form a closed space is effectively solved, resulting in higher positioning accuracy and stronger encapsulation stability.

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 4This utility model provides a special electrode for through-hole pipe caps. The special electrode for through-hole pipe caps includes an upper electrode body 101, a sliding core 102, a venting pressure ring 103, and a spring 104. The upper electrode body 101 has an encapsulation area inside. The encapsulation area is arranged in a three-section stepped structure that is narrow at the top and wide at the bottom. The encapsulation area is composed of a first encapsulation area 105, a second encapsulation area 106, and a third encapsulation area 107 from top to bottom. The sliding core 102 is installed inside the encapsulation area. The venting pressure ring 103 is installed inside the third encapsulation area 107. The bottom of the sliding core 102 is slidably connected to the venting pressure ring 103. The spring 104 is arranged between the upper surface of the venting pressure ring 103 and the top of the sliding core 102.

[0019] In this embodiment, the through-hole cap is inserted into the encapsulation area of ​​the upper electrode body 101. The upper end of the through-hole cap contacts the bottom of the sliding core 102. The encapsulation area forms a closed negative pressure adsorption space, and the gas is allowed to escape through the venting ring 103 to maintain sufficient negative pressure. Under the action of negative pressure suction, the through-hole cap and the sliding core 102 contract upwards until they reach the edge of the protrusion 109 of the through-hole cap, thereby forming a precise positioning of the through-hole cap and achieving the sealing requirements. By adopting the above structure, the problem of the through-hole cap being unable to form a closed space is effectively solved, resulting in higher positioning accuracy and stronger encapsulation stability of the through-hole cap.

[0020] Furthermore, a gas-blocking ring 108 is fixedly provided at the top of the sliding core 102, and a protrusion 109 is fixedly provided on the upper surface of the gas-blocking ring 108. The protrusion 109 is in clearance fit with the first encapsulation area 105, and the gas-blocking ring 108 is in clearance fit with the second encapsulation area 106. The diameter of the gas-blocking ring 108 is larger than the diameter of the first encapsulation area 105.

[0021] In this embodiment, since the diameter of the air-blocking ring 108 is larger than the diameter of the first encapsulation area 105, it is ensured that the first encapsulation area 105 can be effectively sealed when the sliding core 102 moves upward.

[0022] Furthermore, a washer 110 is provided on the upper surface of the vent pressure ring 103, and the washer 110 is disposed on the outside of the bottom end of the spring member 104.

[0023] In this embodiment, the gasket 110 is used to protect the vent pressure ring 103, preventing the vent pressure ring 103 from directly contacting the top of the third encapsulation area 107 and causing wear to the vent pressure ring 103.

[0024] Furthermore, a sliding hole 111 is provided at the center of the vent pressure ring 103, and the bottom end of the sliding core 102 is clearance-fitted with the sliding hole 111.

[0025] In this embodiment, since the bottom end of the sliding core 102 is fitted with the sliding hole 111 with a clearance, the bottom of the sliding core 102 slides more smoothly on the vent pressure ring 103.

[0026] Furthermore, the venting pressure ring 103 is provided with a plurality of vent holes 112, which are evenly arranged around the sliding hole 111.

[0027] In this embodiment, the arrangement of multiple vent holes 112 allows air in the encapsulation area to be quickly extracted, thereby forming a stable negative pressure adsorption force in the encapsulation area.

[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
