ASM wire bonder SG60 Spark Generator 02-89581

Regarding the SG60 Spark Generator—a component for ASM wire bonders (part numbers 02-89581 )—the part number 02-89581 is designated in spare parts catalogs as the SKU for the SG-60 spark generator unit.

Functionally, the SG60 serves as a spark discharge/ignition control module within the wire bonder. Its primary role is to support the EFO (Electronic Flame-Off) system by applying a high-voltage spark to the tip of the gold wire prior to the bonding process. This creates a uniform Free Air Ball (FAB), providing a reliable foundation for subsequent ball bonding. On the ASM Eagle/AERO platforms, the SG60 unit also facilitates signal switching for bond-adhesion detection: during the spark discharge phase, a relay connects the gold wire to the spark generator, while during the actual bonding phase, it switches the connection to the detection circuitry.
