Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding splitters, in particular to a multi-angle micro-hole machining fastening tooling for deep cavity welding splitters. Background Art
[0002] The connection between the internal chip and the external pins in semiconductor packaging plays an important role in establishing the electrical connection between the chip and the outside and ensuring the smooth input / output between the chip and the outside world, and is the key in the entire back-end packaging process. Wire bonding dominates the connection methods due to its simple process implementation, low cost, and applicability to various packaging forms. Wire bonding is one of the main interconnection technologies in packaging. Other technologies include flip chip, wafer-level packaging, and through-silicon via technology. Wire bonding is a method that uses a fine metal wire and utilizes heat, pressure, and ultrasonic energy to tightly weld the metal lead to the substrate pad, realizing the electrical interconnection between the chip and the substrate and the information communication between the chips. The bonding point shapes of wire bonding mainly include spherical and wedge-shaped. Under ideal control conditions, grain boundary sharing and atomic mutual diffusion will occur between the lead and the substrate, so as to achieve atomic-level bonding between the two metals.
[0003] Among them, the splitter is an important tool in the wire bonding process. The wire passes through the wire threading hole on the splitter and reaches the working surface of the tool tip. The working surface of the tool tip presses the wire on the pad of the chip. Through the action of ultrasonic vibration and pressure, the wire and the pad form an atomic bond, so as to form a stable and reliable solder joint between the wire and the chip pad.
[0004] When using the splitter, it is processed by installing the splitter in the installation hole of the tooling. Under different processing requirements, different requirements for the angle of the wire threading hole of the splitter are required. Commonly used wire threading hole angles for deep cavity welding splitters include: 45°, 52°, and 60°, etc. These wire threading angles need to be realized through the installation holes on the tooling at specific angles. In the prior art, in order to achieve angle adjustment, generally one tooling is made for each angle, and one tooling can only achieve one wire threading hole angle, which results in high costs and troublesome tooling replacement.
[0005] In view of this, there is an urgent need for a multi-angle micro-hole machining fastening tooling for deep cavity welding splitters to solve the above problems. Summary of the Utility Model
[0006] Aiming at the problems existing in the prior art, the utility model solves this problem with the following technical structure.
[0007] To achieve the above object, the utility model adopts the following technical solutions:
[0008] A multi-angle micro-hole processing fastening tooling for a deep cavity welding split tool, comprising: a tooling body, on which a first mounting plane, a second mounting plane, a third mounting plane and a fourth mounting plane are arranged. The first mounting plane, the second mounting plane, the third mounting plane and the fourth mounting plane are all arranged on the circumferential side of the tooling body and are connected in sequence. The angles between the first mounting plane and the second mounting plane, between the second mounting plane and the third mounting plane, and between the third mounting plane and the fourth mounting plane are all different;
[0009] The tooling body is provided with a first wire threading hole, a second wire threading hole and a third wire threading hole running through it. The extending direction of the first wire threading hole is perpendicular to the second mounting plane, the extending direction of the second wire threading hole is perpendicular to the third mounting plane, and the extending direction of the third wire threading hole is perpendicular to the fourth mounting plane.
[0010] It is further characterized in that
[0011] The angle between the second mounting plane and the first mounting plane is 135 degrees.
[0012] The angle between the third mounting plane and the second mounting plane is 128 degrees.
[0013] The angle between the fourth mounting plane and the third mounting plane is 120 degrees.
[0014] It further includes a fifth mounting plane, and the fifth mounting plane is connected to the side of the first mounting plane away from the second mounting plane.
[0015] The fifth mounting plane is parallel to the fourth mounting plane.
[0016] It further includes a sixth mounting plane, and both sides of the sixth mounting plane are connected to the sides of the fifth mounting plane and the fourth mounting plane away from the second mounting plane.
[0017] The fifth mounting plane is parallel to the fourth mounting plane.
[0018] Both sides of the first mounting plane, the second mounting plane, the third mounting plane, the fourth mounting plane, the fifth mounting plane and the sixth mounting plane are limiting planes.
[0019] The joints of the first mounting plane, the second mounting plane, the third mounting plane, the fourth mounting plane, the fifth mounting plane, the sixth mounting plane and the limiting planes are all rounded corners.
[0020] Adopting the above structure of the present utility model can achieve the following beneficial effects:
[0021] When the first installation plane is used as the base plane, the second installation plane is the installation plane; when the second installation plane is used as the base plane, the third installation plane is the installation plane; when the third installation plane is used as the base plane, the fourth installation plane is the installation plane. Since the angles between the first installation plane and the second installation plane, between the second installation plane and the third installation plane, and between the third installation plane and the fourth installation plane are all different, when different end faces are selected as the base plane, the angles of the installation plane are all different. This enables a single tooling to place the split tool at different wire threading angles, reducing production costs, improving production efficiency, and saving manpower and material resources.

[0026] In order to enable those skilled in the art of this technology to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.
[0027] It should be noted that the terms "including" and "having" in the description and claims of this utility model and any of their deformations are intended to cover non-exclusive inclusion. For example, a process, method, device, product, or equipment that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or equipment.
[0028] The following is a further detailed description of this application in conjunction with the attached Figures 1-3 drawings.
[0029] As Figures 1-3As shown in the figure, a multi-angle micro-hole processing fastening tooling for a deep cavity soldering split tool includes: a tooling body 1, on which a first installation plane 2, a second installation plane 3, a third installation plane 4, and a fourth installation plane 5 are provided. The first installation plane 2, the second installation plane 3, the third installation plane 4, and the fourth installation plane 5 are all arranged on the circumferential side of the tooling body 1 and are connected in sequence. The angles between the first installation plane 2 and the second installation plane 3, between the second installation plane 3 and the third installation plane 4, and between the third installation plane 4 and the fourth installation plane 5 are all different; a first wire threading hole 6, a second wire threading hole 7, and a third wire threading hole 8 are penetrated through the tooling body 1. The extending direction of the first wire threading hole 6 is perpendicular to the second installation plane 3, the extending direction of the second wire threading hole 7 is perpendicular to the third installation plane 4, and the extending direction of the third wire threading hole 8 is perpendicular to the fourth installation plane 5. In this way, when the first installation plane 2 is used as the base plane, the second installation plane 3 is the installation plane (the end face for installing the split tool). When the second installation plane 3 is used as the base plane, the third installation plane 4 is the installation plane. When the third installation plane 4 is used as the base plane, the fourth installation plane 5 is the installation plane. Since the angles between the first installation plane 2 and the second installation plane 3, between the second installation plane 3 and the third installation plane 4, and between the third installation plane 4 and the fourth installation plane 5 are all different, when different end faces are selected as the base plane, the angles of the installation plane are all different, enabling a single tooling to place the split tool at different wire threading angles, reducing production costs, improving production efficiency, and saving manpower and material resources.
[0030] Among them, in this embodiment, the angle between the second installation plane 3 and the first installation plane 2 is 135 degrees, the angle between the third installation plane 4 and the second installation plane 3 is 128 degrees, and the angle between the fourth installation plane 5 and the third installation plane 4 is 120 degrees. During production, the size of the angle between each installation plane can also be reasonably adjusted according to actual usage requirements. It is also possible to manufacture an integrated tooling with three uncommon angles of 30°, 38°, and 55°, or select any three angles from the common angles of 45°, 52°, 60° and the uncommon angles of 30°, 38°, 55° for combination to make an integrated tooling.
[0031] As Figures 1-2 shown, as Figures 1-2 shown, it further includes a fifth installation plane 9, and the fifth installation plane 9 is connected to the side of the first installation plane 2 away from the second installation plane 3. By setting the fifth installation plane 9, it is convenient to install and position the tooling. Among them, the best angular relationship between the fifth installation plane 9 and the fourth installation plane 5 is parallel.
[0032] As Figures 1-2As shown, the tooling body also includes a sixth mounting plane 10, and the two sides of the sixth mounting plane 10 are respectively connected to the fifth mounting plane 9 and the side of the fourth mounting plane 5 away from the second mounting plane 3. By setting the sixth mounting plane 10, the first mounting plane 2 and the fifth mounting plane 9 are connected, wherein the optimal angle relationship between the fifth mounting plane 9 and the fourth mounting plane 5 is parallel.
[0033] Further optimization is that, in order to facilitate the clamping of the tooling body, both sides of the first mounting plane 2, the second mounting plane 3, the third mounting plane 4, the fourth mounting plane 5, the fifth mounting plane 9 and the sixth mounting plane 10 are limiting planes 11, so that the tooling body is fixed by the two limiting planes 11.
[0034] Further optimization is that in order to reduce the possibility of the tool body hurting the worker's body, the joints between the first mounting plane 2, the second mounting plane 3, the third mounting plane 4, the fourth mounting plane 5, the fifth mounting plane 9, the sixth mounting plane 10 and the limiting plane 11 are all rounded corners to reduce the possibility of scratches on workers by corners.
[0035] In summary, when the first mounting plane 2 is taken as the base plane, the second mounting plane 3 is the mounting plane, when the second mounting plane 3 is the base plane, the third mounting plane 4 is the mounting plane, and when the third mounting plane 4 is the base plane, the fourth mounting plane 5 is the mounting plane. Since the angle between the first mounting plane 2 and the second mounting plane 3, the angle between the second mounting plane 3 and the third mounting plane 4, and the angle between the third mounting plane 4 and the fourth mounting plane 5 are all different, when different end faces are selected as the base plane, the angles of the mounting planes are all different, so that one tool can make the chopping knife at different wire threading angles, thereby reducing production costs, improving production efficiency, and saving manpower and material resources.
[0036] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
