Generally, die bonding machines include a wafer feeding device, a swing arm device, a dispensing device, and a suction-and-carry device. The suction-and-carry device holds the film material, the dispensing device dispenses adhesive onto the film material, and the wafer feeding device holds a blue film sheet, on which the wafer is placed. The swing arm device moves above the blue film sheet, and the wafer feeding device, including a ejector mechanism, lifts the wafer from the blue film sheet. Subsequently, the swing arm device picks up the wafer and transfers it onto the film material, thus bonding the wafer to the film.
[0003] With the development of the semiconductor industry and continuous advancements in die bonding technology, efficiency and accuracy issues remain for die bonding of large-size films. Currently, most die bonding equipment on the market is designed for small-size films, and conventional equipment often cannot meet the needs of large-size films. Common practices for die bonding of large-size films include multiple positioning and segmented die bonding, or the use of specialized large-size die bonding machines. However, these methods all suffer from low accuracy. Multiple positioning and segmented die bonding affect die bonding accuracy and efficiency, while specialized large-size die bonding machines are expensive and not widely applicable.
