Full Description

1.1 These test methods cover tests to determine the shear strength of a series of ball bonds made by either thermal compression or thermosonic techniques. Note 1Common 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 and first bonding operation in the thermal compression and thermosonic process, or both,) the underlying bonding pad, and the ball bond-bonding pad interfacial-attachment area or weld interface.

1.2 These test methods cover ball bonds made with small diameter (from 18 to 76- although it may be contra indicated due to the possible interference with adjacent wire bonds and microcircuit components.

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

1.7 This 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 and health practices and determine the applicability of regulatory limitations prior to use.
