Description

Technical Field

[0001] The present invention relates to the technical field of crystal packaging, and in particular to a fixing device for crystal packaging. Background Art

[0002] In the semiconductor industry, crystal packaging is a key step to protect the chip from the external environment, achieve electrical connection and heat dissipation. During the crystal packaging process, the accurate fixation of the crystal is crucial for subsequent welding, testing and the performance of the final product. When the crystal is fixed, a fixture is used.

[0003] At present, when the fixing device for crystal packaging is in use, although a fine-tuning mechanism is provided at the bottom of the fixing structure, which can make slight adjustments to the fixed crystal in the front, back, left and right directions, during the adjustment process, it is generally adjusted manually or by motor drive. Regardless of the driving method, the driving is usually achieved by rotating the threaded rod structure. The threaded rod structure is prone to loosening during actual use, which in turn affects the fixing effect of the fixing device and reduces the stability of the crystal during the packaging process. In addition, due to the lack of an effective flexible clamping structure on the current fixing device for crystal packaging, the crystal is easily damaged when clamped and fixed, thereby reducing the yield rate of crystal packaging. Moreover, although some of the current fixing devices use the method of manually rotating the threaded rod to move the clamp to achieve the fixing effect of the crystal, although the manual fixing device has a lower cost, it requires a large number of turns when rotating the threaded rod, thereby reducing the fixing efficiency of the fixing device. Summary of the invention

Then, by controlling the left and right fine-tuning motor 206 to operate, another worm 207, another worm wheel 208 and the left and right fine-tuning screws 204 are rotated. Then, the left and right fine-tuning blocks 202 move slightly left and right with the fixed component 3 and the crystal under the action of the thread, so that the position of the crystal during packaging is more accurate. Moreover, since the unfolded helix angle of the worm 207 is smaller than the friction angle of contact with the worm wheel 208, the worm 207, the worm wheel 208, the front and rear fine-tuning screws 203 and the left and right fine-tuning screws 204 can obtain an effective self-locking effect, thereby preventing the front and rear fine-tuning screws 203 and the left and right fine-tuning screws 204 from loosening during actual use.
