Apparatus for thermocompression bonding

Leads are bonded to thin-film conductors on a substrate by the application of heat and pressure of a thermode. The thermode encloses a fusible material, adjacent its tip, which is heated and fused during the nonbonding portion of a bonding cycle. During the bonding portion of the bonding cycle, the...

Zusammenfassung:	Leads are bonded to thin-film conductors on a substrate by the application of heat and pressure of a thermode. The thermode encloses a fusible material, adjacent its tip, which is heated and fused during the nonbonding portion of a bonding cycle. During the bonding portion of the bonding cycle, the fused material supplies the heat of fusion to the thermode tip when the tip contacts the leads. This helps maintain control of the tip temperature.
