xyztec patents

Challenging traditional approaches, xyztec’s dedicated R&D team has developed many innovative technologies that provide a variety of ways to improve bond testing. Some of these developments are protected by patents, granted in Europe, the United States of America, China, Taiwan and/or other territories. Among these are:


Digital creep and drift correction

NL2016315, WO2017146566, PCT/NL2017/050081, EP3420329, US20190072441

Sensor apparatus for determining a deformation due to creep in an output of a sensor, said sensor apparatus comprising force means arranged for applying a mechanical force to said sensor, said sensor arranged for measuring, in a current measurement, a displacement of said sensor caused by said applied force and a processor component arranged for determining said deformation due to creep for a next measurement by said sensor.


Improvements to high force die shear tooling

EP2473832, WO2011028107, CN102770747, ZL201080049812.5, PCT/NL2010/050545

A test device for shear testing semiconductor die bonded to a substrate. Shear block being self aligning and made from a soft material to minimise stresses on the die caused by the test load thereby reducing or eliminating any damage to the die. Different block designs can be made to suit different applications, shear face being tailored to test either single die, die placed very closely to each other or stacked die. The depth of shear face may be less than the die thickness ensuring that the bond surface is not damaged by block during the test.

Solder cleaning system

WO2016012357, PCT/EP2015/066389, CN2017022201023170, CN107073527, GB20140013225, US20170209903, CN107073527 (A)

The present invention provides a method of cleaning solder from the jaws of a solder ball test device. The method comprising the steps of heating a gas to a temperature above the melting temperature of the solder and directing the heated gas over the jaws of a solder ball test device to remove solder from said jaws. An apparatus which for carrying out the method is also disclosed.


A method for determining a strength of a bond and/or a material as well as a bond tester apparatus

PCT/NL2016/050850,  CN108700502A, EP3387412A1, NL2015919B1, US11112350B2, US2018364151A1, WO2017/099590A1

A method for testing a bond using a bond tester apparatus, the method comprising the steps of applying a mechanical force to the bond, determining, by a sensor component comprised by the bond tester apparatus, the applied force to the bond by measuring, by the sensor component, a displacement of the sensor component caused by the applied force and calculating, by the sensor component, the applied force on the basis of a first component which comprises a direct relationship with the measured displacement and on the basis of at least one of a second component, a third component and a fourth component.


Improvements to step back height

WO2019235924, NL2021048, US2021229371 

A bond tester apparatus arranged for determining a strength of a bond and/or a material present on a base, said bond tester apparatus comprising a force measurement module for applying a shear force to said bond and/or said material, and a displacement module and a controller arranged for controlling the distance between the force measurement module and the displacement module such that the shear height of a shear tool can be set.


None contact shear testing


A method of calibrating a sensor of a materials tester, wherein said sensor is arranged to measure a shear force applied by a tool of said materials tester to a sample, for example a wafer or a printed circuit board, said materials tester comprising a shear sensor mount, wherein said sensor is mountable on said shear sensor mount, wherein said method comprises the steps of accelerating said shear sensor mount over a predefined distance towards and/or away from said sample; measuring, by said sensor, a relative movement of said shear sensor mount; calibrating said measured relative movement to an acceleration of said shear sensor mount, thereby testing operation of said sensor.
