Used ASM AD 889 #197316 for sale

ASM AD 889 is an autocollimator with an attached rotary die attacher for the accurate alignment and placement of die attach adhesives in the electronics assembly process. This unit is manufactured by Varitronix, an industry leader in die attach and inspection systems. ASM AD889 is designed for simplified end-point scanning, rapid adhesive placement and increased production efficiency. The general mechanism of AD 889 consists of three components: an 88 mm perforated base plate, a die attacher, and a die attachment head. The base plate is mounted to the benchtop of the production line and provides guidance for precise placement of the adhesive. The die attacher is then affixed to the base plate and is designed with an adjustable nozzle holder as well as a built-in perforated plate alignment mechanism for die placement accuracy. The adhesive is dispensed from a refillable container positioned in the attachment head, which can be adjusted to the optimal position for application to the die. AD889 is capable of attaching dies at speeds of up to 1 die per second, with a die size range of 0.25mm to 12mm. This unit is also equipped with a pressure control equipment to ensure consistent adhesive dispense, as well as a patented dual-jaw translation clamping system which accurately holds the die in place during bonding. The die attachment accuracy of ASM AD 889 is ± 0.01mm for X, Y and Z axes, ensuring accurate placement and end-to-end bonding of the dies to the substrate. Furthermore, the unit is programmed with an auto-tuning mode, which recognizes the position of the die and adjusts the parameters for bonding process optimization. ASM AD889 also features high-resolution imaging and inspect modes, programmed to detect any surface contaminants or defects. The unit also includes a wafer centering and alignment function for automated wafer placement and verification. The control unit for AD 889 includes an interactive GUI (graphical user interface) combined with a menu-driven machine for simplified operation. Overall, AD889 is an efficient, accurate and repeatable die attacher which is designed for easy operation and optimal performance in the electronics assembly process. With its high-resolution imaging capabilities and sophisticated automated functions, it is the perfect tool for large scale production and a reliable choice for reliable on-site bonding.
