The probe consists of different components, each carefully chosen for its properties and characteristics. The top and bottom plungers are made of BeCu (Beryllium Copper) and are Au (Gold) plated. This combination provides excellent conductivity and corrosion resistance, ensuring reliable electrical contact during testing. The barrel is made of P.B. (Phosphor Bronze) and is also Au plated, further enhancing its conductivity and protecting against oxidation. The spring is made of Music Wire, a high-quality steel alloy known for its strength and durability, and is also Au plated to resist corrosion.
In terms of mechanical specifications, the probe has a spring force of 11 grams at 0.65mm. This force ensures firm and consistent contact with the semiconductor device under test, allowing for accurate and reliable measurements. The full travel distance of the probe is 1.0mm, indicating the maximum distance the probe can move during testing. The recommended travel distance is 0.65mm, which suggests the optimal operating range for precise testing.
The probe has a mechanical life of 50K, meaning it is designed to withstand repeated use over a significant number of testing cycles. This longevity ensures reliable performance and consistent results throughout its lifespan.
In terms of electrical specifications, the probe has a current rating of 0.3A, indicating its ability to handle a maximum current without compromising performance. Additionally, the probe has a self-inductance of 1.15nH, which measures the ability to store energy in the probe's magnetic field, and a capacitance of 1.38pF, which measures the ability to store electric charge. These specifications are crucial for accurate signal transmission and measurement in high-frequency applications.
The probe also demonstrates excellent bandwidth performance, with a measured -0.047dB attenuation at 20GHz. This characteristic ensures minimal signal loss and accurate measurements in high-frequency testing scenarios.
