probeIt is actually a high-end precision electronic component mainly used in electronic products such as mobile phones, playing a connecting role. The test probe introduced in the article is equivalent to a medium. During testing, the probe's head can be used to contact the test object, while the other end is used to conduct signals and transmit current. There are various types of probes available, which can be used to handle different testing points, such as pointed, round, claw, etc.
All test probes are composed of probe tips, needles, and springs. The selection of probe materials should not only consider technical application, production capacity, and cost factors. Finally, summarize the best probe material selection plan. Common probe materials include beryllium copper, high carbon steel, brass, palladium alloy, bronze, etc.
High carbon steel is commonly used to produce all sharp probe head types or ultra long durable probes. This material has high hardness and sharpness, and its hardness is higher than that of beryllium copper. Therefore, it ensures the good durability and reliable connectivity of the probe.
Beryllium copper, commonly used in the production of needles and contact components, is also suitable for producing high current probes and springs. This material has excellent mechanical properties and high conductivity in one. This also ensures long-term performance and durability optimization of the contact position.
Brass, commonly used in circular probe head shapes and processed needle sleeves. This material has excellent wear resistance, excellent mechanical properties, and high conductivity.
Palladium alloy, commonly used as a probe tip, does not require coating. This material has super strong hardness characteristics.
Spring: Installed inside the needle tube to make the probe elastic, mainly made of stainless steel wire and piano wire.
Stainless steel wire:It is the preferred material for probe springs due to its corrosion resistance, high temperature resistance, and resistance to rusting.
Qin steel wire:Strong elasticity, but prone to rusting when exposed to moisture.
Regardless of the material used, it must be determined based on the performance requirements of the components to ensure optimal lap reliability.
