High-speed bond testing maximizes your units per hour (UPH) significantly. The standard Sigma* comes with a high axis speed of 50 mm/s, a direct-drive motor, and mapped linear positional encoders to ensure very accurate positioning.
Many systems rely on rotary encoders fixed to their drive motors. This system does an adequate job of positioning the motor. Backlash and hysteresis in gearboxes, lead screws, and linear guides induce very significant systematic errors of ±50 µm.
*Floor-based Sigmas come with high-speed axis of 500 mm/s and 10 nm encoders.
A controlled study with experienced users shows that the throughput of a Sigma compared to the most competing system is up to 39% faster.
Testing the bond without any movement of the sample is essential for obtaining reliable, reproducible measurements. The fiducial pattern recognition capability combined with precision XYZ stages, consistently maintains initial tool alignment to within ±5 µm within the entire test volume with 0.5 µm repeatability. Our wide range of standard and customized work holders allows precise sample clamping with a system stiffness of 1 µm/10 kg.
Exchangeable work holders allow rapid production setup for all samples. If a work holder is not suitable for your sample, the quick release handle enables you to take off the work holder in seconds. This interface provides a secure lock capable of withstanding 200 kgf while maintaining reproducible positioning.
To keep the sample locked in position, a vacuum and/or clamping system is most common for low force measurements or flexible substrates. When testing higher forces, you can rely not only on our dedicated selection of standard work holders but also on custom designs for perfect sample clamping.
