Description

Technical Field

[0001] This utility model relates to the field of chip processing technology, specifically to a chip surface cleaning device. Background Technology

[0002] A chip is a general term for semiconductor components and is the carrier of integrated circuits. Chips are one type of integrated circuit. Chips are characterized by supporting high-speed data transmission, enhancing system security, and serving as a highly efficient and reliable communication interface chip. If impurities are mixed into the chip during production, it will affect the emission of electrons, thereby affecting the amplification performance and lifespan of the vacuum tube.

[0003] Chip packaging combines the chip with a casing, serving to house, fix, seal, protect the chip, and enhance its electrothermal performance. The contacts on the chip are connected to the pins of the package casing by wires, and these pins are then connected to other devices through wires on the printed circuit board.

[0004] During the packaging process, chips are typically cleaned using cleaning devices. Existing technology includes a Chinese patent with authorization announcement number CN219541074U, entitled "A Chip Surface Dust Removal Device," which discloses a chip surface dust removal device comprising a base, a motor fixedly mounted on the outer wall of the base, a threaded rod fixedly mounted on the outer edge of the motor's output shaft, a slider threadedly connected to the outer edge of the threaded rod, and a placement plate fixedly mounted on the top of the slider.

[0005] The aforementioned patent describes a slider connected via a threaded rod's outer thread, allowing it to move under force. A mounting plate fixed to the top of the slider, along with a third motor, drives a brush to rotate, achieving reciprocating cleaning of the chip. While existing technologies, including this patent, can meet the cleaning needs of chip surfaces to some extent, achieving a simple cleaning effect using complex power mechanisms requires a sophisticated control system to manage multiple mechanisms, leading to a more cumbersome manufacturing process and significantly increased production costs. Therefore, these technologies have certain shortcomings. Utility Model Content
