InfinityXT增强并扩展了FormFactor行业领先的Infinity探头系列，该系列十多年来一直为设备表征和建模领域的准确性和可重复性设定基准。随着市场的发展，新的 InfinityXT 系列以更高的温度范围、更好的探头可见性和耐用性以及对更窄间距的支持，进一步提升了行业标准。

最近，在汽车、移动通信/5G和物联网设备市场的推动下，射频和微波设备行业经历了爆炸式增长。新的InfinityXT探针的开发一直是由这些高增长市场的需求所指导的。这些要求包括设备建模和表征的超宽带宽和宽温度范围。用于建模的设备测量是最需要在晶圆上的测量应用之一，需要极高的测量精度和可重复性，因为提取的参数对非常微小的差异非常敏感。

Features / Benefits

•40 GHz, 50 GHz, 67 GHz and 110 GHz versions available.

• Excellent return and insertion loss combined with low and repeatable contact resistance on aluminum pads. This helps to ensure high-accuracy S-parameter measurements to meet the requirements of the most demanding applications

• Industry-leading solution for small pad, tight pitch, RF probing needs. Small, lithographically-defined contacts with a contact area of 12 μm W x 5 μm L. When combined with a new mechanical architecture to improve the skate vs overtravel ratio and excellent probe tip visibility for precise probe placement, enables probing of tight pitch, small pads.

• Standard pitches down to 45 μm with the ability to support pitches as small as 25 μm (for pitches 4 W (20 GHz), 2 W (67 GHz), 1 W (110 GHz)

》Contacts/Scrub/Performance Examples

SEM image of InfinityXT 100 µm pitch contacts highlights the highly visible, small 12 µm wide contacts.

InfinityXT GSG-50 scrub marks at progressively higher overtravel levels of   13, 25, 50 and 75 µm. Highly uniform scrub yields very high repeatability in your measurements.

The unique mechanical architecture of the InfinityXT probes provide higher force with less overtravel (OT) during the first 2 mils of over-     travel.   This helps to ensure that you achieve     good contact resistance at lower OT settings,    mean less skate and the ability to probe on smaller pads. This same unique architecture   enables significantly higher OT levels without   damage to the probe as the force levels offat higher levels of overtravel.

Performance Examples (continued)

Typical Insertion Loss thru 110 GHz for a GSG 50 µm   (   - spec limit)

Typical Return Loss thru 110 GHz for a GSG 50 µm probe (specifications can vary slightly by pitch;   - spec limit)

Performance Examples (continued)

Probe to probe isolation, shown at two separations. The blue curve shows 200 µm probe-to-probe separation and the

green curve shows 500 µm separation.
