What is the role of high-frequency probe, RF probe and high-current probe in test probe?


The test probe serves as a developmental electronic component, overseeing the examination of signals and quality concerns within electronic control circuits. It proficiently captures signals without any loss, subsequently forwarding them to the corresponding test data system for thorough research and analysis.

The transmission of the current signal occurs through the cable bundle of the tester to the probe casing, and from there, it proceeds through the probe tip to the designated test point. The operational principle of these test probes involves assessing the open and short circuit parameters of circuit boards through the transmission of current signals.high voltage probe The test system inputs the transmitted current into the device under examination, gauging the device's response to the input signal.

Test probes, when categorized based on structure and application in the research field, exhibit various types such as shrapnel probes, cantilever probes, and vertical probes. Their application in technology development spans semiconductor test probes, high-frequency data test probes,wafer chuck RF module test probes, high-current control test probes, conventional ICT probes, and more.

High-frequency test probes, essential for PCBs, high-speed digital circuit boards, wafers, and low impedance, wear-resistant microwave chips, offer versatility with a range of head types. Tailoring high-frequency wire length and wire type to meet customer requirements, these probes can operate at frequencies as low as 2.4GHz with an attenuation of -1.5dB. They demonstrate excellent performance in testing laptops, wireless network cards,manual prober and Bluetooth devices, ensuring reliable connections and convenient usage.

RF system testing through specialized probes, crafted from beryllium copper, showcases outstanding conductive network performance. The durability of these probes is notable, contributing significantly to the testing processes of micro-switches, plug connectors, and circuit boards. RF test probes are integral in the technology development, parameter extraction, performance debugging, and production testing of RF products, enhancing efficiency, reducing test time, and cutting down on development costs.

In the realm of high-current test probes, these components are designed to withstand and conduct large test currents, particularly in applications with high temperatures. Industries requiring high-current probes leverage their usage in functional tests, signaling, production tests, and as built-in shock elements. The current-carrying capacity of high-current test probes depends on intrinsic factors such as probe core area, material conductivity, and insulation conductivity. A thicker probe core, high-purity copper in the conductive material, and effective thermal conductivity in the insulating material collectively enhance the conductivity and current-carrying capacity of the high-current test probe.
