Full Description

1.1These test methods cover tests to determine the shear strength of a series of ball bonds made by either thermosonic or thermal compression techniques using either gold or copper wires.

Note 1:Common usage at the present time considers the term ball bond'' to include the enlarged spheriodal or nailhead portion of the wire, (produced by the flameoff/spark [EFO] and first bonding operation in the thermosonic [or thermal compression] process), and the ball bond-bonding pad interfacial-attachment area or weld interface.

1.2These test methods cover ball bonds made with small diameter (from 18 to 76-m (0.0007 to 0.003-in.)) gold or copper wire of the type used in integrated circuits and hybrid microelectronic assemblies, system on a chip, and so forth.

1.3These test methods can be used only when the ball height and diameter are large enough and adjacent interfering structures are far enough away to allow suitable placement and clearance (above the bonding pad and between adjacent bonds) of the shear test ram.

1.4These test methods are destructive. They are appropriate for use in process development or, with a proper sampling plan, for process control or quality assurance.

1.5The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
