Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of microelectronic assembly, in particular to a pair of high-precision tweezers for clamping microwave chips. Background Art
[0002] In microelectronics assembly, in addition to the automatic nozzle machines and suction nozzles used in large-scale production, there are many application scenarios that require manual tweezers to pick up microwave chips and perform operations such as picking up, releasing, and rubbing (bonding, eutectic).
[0003] Existing tweezers are prone to the following problems when gripping large and easily brittle microelectronic chips: 1. The end of the tweezers is too small (only 0.02 mm wide), which makes the clamping area too small. The chip is large and the small clamping area can easily cause the chip to flip during the clamping process; 2. The tip of the tweezers is too thin, which can easily cause the edge of the chip to crack.
[0004] In view of this, there is an urgent need for a microwave chip clamping high-precision tweezers to solve the above problems. Utility Model Content
[0005] In view of the problems existing in the prior art, the utility model solves the problems with the following technical structure.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A high-precision tweezers for clamping microwave chips, comprising: a tweezers body, wherein the tweezers body comprises two clamping arms and two clamping heads respectively arranged at the suspended ends of the two clamping arms;
[0008] The clamping head and the corresponding clamping arm form an angle in the clamping direction, and the ends of the two clamping heads close to each other are the clamping planes.
[0009] It is further characterized in that
[0010] The length of the clamping plane is 0.2 mm to 0.3 mm.
[0011] The width of the clamping plane is 0.05 mm to 0.1 mm.
[0012] The two clamps have arc surfaces facing away from each other.
[0013] The radius of the arc surface is millimeters.
[0014] The clamp is provided with an antistatic coating.
[0015] The clamp is made of antistatic material.
[0016] One end of the two clamping arms away from the clamping head is sleeved with a grip sleeve.
[0017] The grip sleeve is made of antistatic material.
[0018] The grip sleeve is provided with an anti-slip sheet.
[0019] The above structure of the utility model can achieve the following beneficial effects:
[0020] By forming an angle between the chuck and the clamping arm and setting the suspended end of the chuck as a clamping plane, when clamping the chip, the two clamping planes contact the chip, and the contact area is large, which reduces the possibility of chip edge cracking when clamping the chip and also reduces the possibility of chip flipping during the clamping process.

[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0025] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0026] The following is combined with Figure 1-2 This application is described in further detail.
[0027] like Figure 1-2 As shown, a high-precision tweezers for clamping microwave chips comprises: a tweezers body, the tweezers body comprises two clamping arms 1 and two clamps 2 respectively arranged at the suspended ends of the two clamping arms 1;
[0028] The clamping head 2 and the corresponding clamping arm 1 form an angle in the clamping direction. The ends of the two clamping heads 2 that are close to each other are the clamping plane 3. The length of the clamping plane 3 is 0.2 mm to 0.3 mm (for example, 0.24 mm), and the width of the clamping plane 3 is 0.05 mm to 0.1 mm (for example, 0.07 mm).
[0029] Based on the above structure, an angle is formed between the chuck 2 and the clamping arm 1, and the suspended end of the chuck 2 is set as the clamping plane 3. When clamping the chip, the two clamping planes 3 contact the chip, and the contact area is large, which reduces the possibility of chip edge cracking when clamping the chip, and also reduces the possibility of chip flipping during the clamping process.

[0031] In actual use, the above arrangement makes it possible to reduce the space requirement for the tweezers when in use, which is beneficial for avoiding other related parts when in use. The optimal radius of the arc surface is 7 mm.
[0032] It is further optimized that an antistatic coating is provided on the chuck 2 or an antistatic material is used as the material for making the chuck 2 .
