Used ASM AB 520 #9079270 for sale

ASM AB 520 is an advanced automated bonder specifically developed by ASM Assembly Systems for high volume production of microelectronics assemblies. This bonder is capable of achieving bond times below two milliseconds and contact forces up to 200g. Its mechanical motion is precise, constantly repeating the same movement pattern block-by-block, while the temperature of the bonding die is monitored and actively adjusted. The bonding process begins with the two opposing contact surfaces being brought together, establishing a contact between pads on the surfaces of two substrates. The surfaces are then heated and pressurized to a predetermined limit of contact force and temperature. As soon as the bond is formed, the heat and pressure are released and the bonder moves to the next contact. The bonder's precision is ensured by a unique design, including micro-stepper motor technology, adjustable heated heating plates which are separated by air gap, dual thermocouples for temperature control, one dedicated to the heating plates and another linked to a thermistor on the tip of the bonding tool, and a sophisticated thermal control equipment that delays the temperature rise of the heated area until just before bonding takes place. Due to its high bonding precision, the system works well for die sizes from 01005 up to 7x10mm (5060 mil) and various connectors. The bonder also features an advanced vision unit designed to measure bond integrity and solder paste spread which is based on the 3D sensing technology allowing it to measure height and tilt of the components as well as fine pitch vision machine allowing the bonder to align the substrate accurately for bonding. To further ensure reliable and correct operation, AB 520 is equipped with an Automatic Tool Balancing feature, which monitors tool centrifugal forces and stops the tool when balance threshold is exceeded. All necessary parameters are stored in the tool and their values can be quickly changed via the users intuitive user interface. As for safety features, the asset includes both safety barriers and catches that can be operated remotely, as well as an emergency stop feature for fast shut down in case of emergency. Additionally, the model is compliant with EN ISO 13849-1 safety regulations. Overall, ASM AB 520 is an advanced automated bonder designed for high volume production. The equipment offers superior precision bonding capabilities and multiple safety features that ensure reliable and safe operation.
