ASM AD 838 die attacher is a semi-automatic die-bonding machine designed for high accuracy and speed. It is specifically used for lapping flat metal plates, such as components for semiconductors. The machine operates by using a pneumatic equipment to attach the bonding die to the plates without using conventional methods such as soldering. ASM AD838 can manipulate the bond plates up to a size of 180mm x 400mm, with a maximum die height of 60mm. It requires air pressure of 6 bar and a power supply of 480V, 3-phase / 400V, 3-phase, 3mA max. The die attachment process of AD 838 is a highly precise procedure. The machine uses a vacuum securement and an alignment pin to position the die during attachment. The vacuum provider type is a diaphragm pump with compressed air. The die is aligned with the plate using sensors that are mounted on the machine. This provides a coordinate system for the precision of the lapping process. The vacuum securement provides a strong hold to accommodate the stresses created by the die lapping process. AD838 has a host of features to enhance the efficiency and accuracy of the die lapping process. The machine is equipped with a pre-lapping motor that regulates the die speed based on the surface of the plate. Re-tensioning of the pressure roller is done with a pneumatic motor, and the lapping pressure is adjustable. The machine also features an abrasive-water reservoir to provide water to the die-lapping process and a water-actuated hopper for clean up after lapping. ASM AD 838 also has an alignment and registration inspection unit, which helps ensure die attachment accuracy. The inspection machine uses magnifying cameras and zoom/focus/brightness controls to inspect each die attachment point for accuracy and quality. This tool also assists in detecting errors in the die mounting process, such as too small a gap between the die and the plate or incorrect alignment of the die. Overall, ASM AD838 is an accurate and reliable die attacher because it is capable of precise die mounting. It uses easy-to-use controls to provide precise and reliable die lapping, while the alignment and registration inspection asset helps guarantee die-mounting accuracy. This makes AD 838 an ideal tool for high-volume and high-precision die attachment needs.
