Description

Technical Field

[0001] This utility model relates to bonding fixtures, specifically to an anti-scratching aluminum wire bonding fixture. Background Technology

[0002] Aluminum wire bonding machines use fine metal wires to tightly bond metal leads to pads on a substrate or frame, achieving electrical interconnection between chips and substrates and information exchange between chips. DIP is a dual in-line package for integrated circuits, rectangular in shape with two rows of parallel metal leads on both sides, called pin headers. When fixing the circuit, the pin headers must be inserted into a DIP matrix fixture.

[0003] The existing DIP matrix clamps are made of aluminum alloy, which has relatively high hardness. During insertion and removal, they can cause scratches or abrasions to the inside of the pins. In severe cases, they can also cause pin deformation, resulting in products that do not meet the standards and have a low bonding yield. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem that existing clamps cause scratches or abrasions to the inside of the pins during insertion and removal, and in severe cases, even lead to pin deformation. This invention provides a scratch-resistant aluminum wire bonding clamp.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A scratch-resistant aluminum wire bonding clamp includes a base, on the upper surface of which are provided multiple parallel T-shaped fixing plates.

[0007] The top of the T-shaped fixing plate is provided with multiple strip-shaped blocks evenly distributed along its length.

[0008] A positioning groove is formed between two adjacent strip blocks, and an adhesive layer is provided in the positioning groove. The upper surface of the adhesive layer is lower than the upper surface of the strip block.

[0009] Furthermore, the upper surface of the base is provided with multiple parallel mounting slots, the same number as the T-shaped fixing plates.

[0010] The T-shaped fixing plate is installed on the upper surface of the base through the mounting slot.

[0011] Furthermore, the T-shaped fixing plate is interference-fitted with the mounting groove on the upper surface of the base.

[0012] Furthermore, the adhesive layer is PIND double-sided adhesive, and the lower surface of the PIND double-sided adhesive is adhered to the positioning groove.

[0013] Furthermore, the upper surface of the base is provided with multiple countersunk holes, which, in conjunction with bolts, fix the base to the workbench.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The anti-scratch aluminum wire bonding fixture provided by this utility model sets a T-shaped fixing plate and then fixes the tube shell to the top of the T-shaped fixing plate through an adhesive layer. Since the pins of the tube shell will not directly contact the T-shaped fixing plate, the risk of damage or deformation of the tube shell pins during the fixing process can be avoided. At the same time, by setting multiple evenly distributed strip blocks to form multiple positioning grooves on the top of the T-shaped fixing plate, it is convenient to fix the position of the tube shell placed on the T-shaped fixing plate, which helps to improve the bonding efficiency and the consistency of the bonding process.

[0016] 2. The anti-scratch aluminum wire bonding clamp provided by this utility model uses PIND double-sided adhesive to fix the tube shell in the positioning groove, which can ensure the stability of the tube shell installation on the one hand, and protect the tube shell on the other hand.

[0021] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 As shown, an anti-scratch aluminum wire bonding fixture includes a base 1, and a plurality of parallel T-shaped fixing plates 2 are provided on the upper surface of the base 1.

[0023] In order to fix the position of the fixed tube shell on the T-shaped fixing plate 2 and improve the bonding efficiency, the top of the T-shaped fixing plate 2 is provided with multiple strip blocks 3 evenly distributed along its length direction; a positioning groove 4 is formed between two adjacent strip blocks 3, and an adhesive layer 5 is provided in the positioning groove 4, with the upper surface of the adhesive layer 5 being lower than the upper surface of the strip block 3.

[0024] In this embodiment, the tube shell is fixed to the positioning groove 4 on the top of the T-shaped fixing plate 2 by the adhesive layer 5. Since the pins of the tube shell will not directly contact the T-shaped fixing plate 2, the risk of damage or deformation of the tube shell pins during the fixing process can be avoided.

[0025] like Figure 1 and Figure 3 As shown, in order to fix the T-shaped fixing plate 2 to the base 1, multiple parallel mounting slots are provided on the upper surface of the base 1, and the number of mounting slots is the same as that of the T-shaped fixing plate 2; the T-shaped fixing plate 2 and the mounting slots on the upper surface of the base 1 are interference fit.

[0026] like Figure 1 As shown, in order to fix the tube shell in the positioning groove 4, the adhesive layer 5 is PIND double-sided tape, and the lower surface of the PIND double-sided tape is adhered to the positioning groove 4. By attaching the tube shell in the positioning groove 4 with PIND double-sided tape, on the one hand, the stability of the tube shell can be ensured, and on the other hand, because PIND double-sided tape is soft, it can protect the tube shell fixed on the PIND double-sided tape.

[0027] like Figure 1 and Figure 2 As shown, in order to fix the base 1 to the worktable of the bonding machine, multiple countersunk holes 6 are provided on the upper surface of the base 1. The countersunk holes 6 cooperate with bolts to fix the base 1 to the worktable.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
