Gold/copper ball shear #
The gold ball bond measurement unit can be fitted to any of our machines. Precise alignment to the bond is simple and stress free using the standard EZ controls. Precise shear height control and force measurement ensure accurate data with minimum distribution. Password protected flexibility of the programmable test parameters allow you to be in control.
An optional camera system is available for visually inspecting the test result. Xyztec complies with all relevant international standards such as ASTM, MIL.
