Used ASM AD 828 #9311922 for sale

ASM AD 828 is a die attacher used for attaching dies onto substrates. It is an automated die-bonding system which eliminates manual handling and increases productivity. ASM AD828 is equipped with a point-to-point servo positioning system which provides highly accurate placement of dies onto the substrate. Its distinct features include a box feeder for loading dies quickly and efficiently, a vision recognition system for inspecting die orientation and a built-in electric discharge protection for die protection. It also has a large working table and a wide scanning range which allows accurate scanning for precise die placements. The machine operates in a cycle mode where dies are placed onto the substrate for visual inspection and then picked up by AD 828 vacuum nozzle which firmly grips the die. The nozzle then moves the die to the designated placement area on the substrate and automatically dispenses adhesive. The unit has a pressure control monitor which ensures adhesive dispense is consistent. After adhesive is applied, the nozzle presses down and heat is applied in order to bond the die onto the substrate. The pressure contained within the adhesive layer between the die and the substrate is monitored throughout the process to ensure precise bond strength. Once the adhesive is cured, the nozzle releases the die and moves to the next die on the substrate. AD828 is designed to meet the most demanding production requirements and its capabilities include the placement of chips ranging in size from 0.5 mm to 20 mm and die pitched sizes from 0.08 mm to 1.27 mm. It also supports applications requiring temperatures up to 200°C and high bond line strength requirements. The machine also has integrated maintenance program which enables preventative maintenance to be carried out at scheduled intervals to reduce downtime and any further maintenance requirements. Overall, ASM AD 828 is an invaluable piece of machinery which allows for accurate and consistent die placements on substrates and a high level of production efficiency.
