Precise tool alignment is essential to test the correct bonds correctly. Concentricity correction achieves tool eccentricities less than 5 µm, and unique tool designs can be of help during alignment.
We offer solutions in customized hook foot lengths or a self-aligning shear tool, which corrects for any tiny but important angular difference between tool and sample.
Using the camera and deep access tooling allows you to test complex sample architecture. And you can easily switch between different tools in seconds with our unique rotating 6-in-1 test head RMU.
Precise hook concentricity is essential (especially with automated wire pull) to ensure you test only the correct wire and to avoid the simultaneous pulling of multiple wires. With software concentricity correction you can achieve eccentricities less than 5 µm. The 360° tool rotation has a standard accuracy of ± 10 µm with 1° sensor rotation resolution.
When parts of the sample obstruct optical access from microscope to test point, special deep access tooling and flexible cameras enable testing of complex sample architectures. The standard Sigma and the floor standing HF offer 50 mm and 80 mm of deep access, respectively, maintaining clear visual access too.
Quickly and easily select the correct tool from the Revolving Measurement Unit (RMU). The RMU switches between 6 housed sensors and goes to a maximum of 200 kgf. Any combination of pull, push, and shear sensors, including USB Tweezers is possible.
