FormFactor ACP Probe – Coaxial

Introducing the FormFactor ACP Probe – Coaxial

The Air Coplanar Probe (ACP) is a rugged microwave probe with a compliant tip for accurate, repeatable measurements for both on-wafer as well signal integrity applications. It features excellent probe-tip visibility and the lowest loss available. The ACP Probe delivers outstanding compliance for probing non-planar surfaces.

These probes offer stable and repeatable over-temperature measurements, with a typical probe life of 500,000 contacts on gold pads. Configurations for both single and dual signal applications are available.

Key Features

• Unique Air Coplanar tip design with choice of beryllium copper (BeCu) or tungsten tip material
• DC to 110 GHz models available in single and dual line versions
• Low insertion and return loss with ultra-low-loss ( -L ) versions
• Excellent crosstalk characteristics
• Wide operating temperature -65 ° C to + 200 ° C
• Wide range of pitches available, from 50 to 1250 µm
• Individually supported contacts
• Reduced contact (RC) probe tips for small pads
• BeCu tip provides rugged, repeatable contact on gold pads

Key Benefits

The ACP probe combines outstanding electrical performance with precise probe mechanics, and is today’s most widely used microwave probe. Fast delivery is available on 100, 125, 150, 200, and 250 µm pitched probes.

Specifications

The ACP40-GSG-xxx probe features include:
