Infinity 3.5 Time Extended Life Bonding Capillaries
In wire bonding, load-up on the capillary face is inevitable as the bond touchdown increases. This is mainly due to the scrubbing action of the capillary from the ultrasonic energy applied in the process of making bonds. As the load-up amount increases, bond quality is affected. The useful life of the capillary can be defined as the maximum bond number before the bond quality produced by the capillary is deemed unacceptable. Depending on the types of substrate and bonding condition, the tool life of the capillary can vary from a few hundred thousand bonds to more than 1 million bonds.
A SPT proprietary process has been developed to extend the bonding tool life by at least three times its current limit, utilizing state-of-art controlled high purity process that enhances the sub-surface properties of the ceramic based material. Through various in-house testing and user evaluations, the long life capillary has proven to exceed the current tool life by at least 2 times the standard.
Failure Rate Distribution as a Function of Tool Life Comparing Infinity and Non-Infinity Capillary
Long life capillary at least 3X of its original.
No change in the bonding parameters.
Higher mean time before failure (MTBF).
Less bonder downtime; higher production output.
Capillary Part Number Selection Guide
The capillary design selection guide is always based on specific device & package configuration, wire type, and wire bonder. The selection of capillary part number process is simplified as follows:
Capillary Tip The selection of capillary tip design is determined by the device and metallization, bond pad pitch, bond pad opening, wire size, target mashed ball diameter, and critical loop height to derive the hole diameter(HD), chamfer diameter (CD), chamfer angle (CA), tip diameter (T) and face angle (FA).
Shank Style The shank style selection is characterized by geometrical design of the capillary bonding tool as dictated by specific device and / or package configuration.
Surface Finish The selection of a particular capillary tip surface finish hinges on whether the application is for gold or copper wire bonding.
Material Capillary material selection for optimum tool life performance for a given bonding application.
Wire Type The proper selection of capillary design is a resultant of the various wire bonding considerations.
