Description

Technical Field

[0001] This invention relates to infrared detector component assembly technology and high-reliability wire bonding technology, and in particular to a fully automatic wire bonding machine with universal tooling for multiple specifications of products and its manufacturing method. Background Technology

[0002] Infrared remote sensing instruments are characterized by high detection accuracy and strong environmental adaptability, and are widely used in fields such as detection, intelligence reconnaissance, precision strikes, night vision, and meteorological observation. Currently, as infrared detectors develop towards ultra-long linear arrays and ultra-large arrays, higher demands are being placed on the assembly technology of infrared detector components.

[0003] In the assembly of infrared detector components, wire bonding is typically used to extract electrical characteristics. Wire bonding dominates the field of interconnect technology due to its low cost and high efficiency. Fully automated wire bonding technology is a modern, high-tech microelectronic packaging technology that integrates precision mechanics, automatic control, image recognition, optics, and ultrasonic thermoforming. It can efficiently and reliably interconnect infrared detector chips, electrode plates, and connectors to achieve signal transmission.

[0004] In typical standardized production, the loading platform of a fully automatic key press is often designed for a fixed product, resulting in low compatibility with components of different specifications. When the same machine is used with components of multiple specifications, it is often necessary to disassemble and replace the components mounted on the platform, which reduces lead wire efficiency and negatively impacts product reliability. In the production environment of multi-specification infrared detector components, there is an urgent need for a tooling that can adapt to various component specifications to improve the product changeover flexibility and equipment utilization efficiency of the fully automatic key press.
