What are the advantages of a rotating probe?
Release date:
2021-09-07
The rotary probe, a dual‑ended probe, is a precision electronic hardware component consisting primarily of three parts: a spring, a probe tube, and a probe tip. It is also known as a “spring pin.” While the name suggests it involves a spring, it is not literally a pin made of spring material—this is a common misconception. In fact, it incorporates an internal spring mechanism, which is quite distinct from a conventional spring. As a highly precise electronic component with powerful functionality, let’s now explore the key advantages of the rotary probe.
The rotary probe, a double‑ended probe, is a precision electronic hardware component consisting primarily of three parts: a spring, a probe tube, and a needle tip. It is also known as a “spring pin.” At first glance, one might assume that a spring pin is made entirely of spring material, but this is incorrect. While it does incorporate a spring mechanism internally, it is quite different from a conventional spring. As a highly precise electronic component, it performs critical functions. Now, let’s explore the key advantages of the rotary probe.
Rotating probes are widely used, primarily in mobile phones, computers, and telecommunications. Virtually every industry that relies on integrated circuits is advancing the adoption of semiconductor testing technologies, with the chip‑packaging test segment representing the largest demand.
1. Products suitable for double-ended probes and rotary probes
The rotary probe with dual heads is suitable for products that require quick connection to both ends of the pin. Both ends can be mated with a PCB and another component, eliminating the need to solder one end; this flexible mating makes it ideal for housing-type connectors—such as watch cases and speaker housings in mobile phones—that do not require soldering. During the assembly process, different springs must be installed inside the tubing in two separate steps, increasing the complexity of spring‑and‑tube assembly. In mass production, adding an extra step for installing each spring can reduce overall throughput.
2. Advantages of the rotary detector and dual-head detector:
1) All components are subjected to vacuum plating, hard gold plating, and thick gold‑nickel plating; the plating offers excellent wear resistance and ensures stable electrical resistance and reliable contact performance.
2) The needle bar is subjected to heat treatment to enhance its hardness and toughness.
3) Meet the requirements of RHOS;
4) The rotating probe features a needle tube with tight tolerances and a high-hardness spring that offers excellent fatigue resistance.
5) Imported lathes: tight tolerances and excellent surface finish;
6) Precision‑assembled grinding wheel, resulting in minimal vibration and smooth sliding;
7) Etching 3360 enhances the adhesion of the plating layer: at both ends of the same probe;
8) Rotational probe for measuring the coating thickness of locally different materials. To ensure optimal wear resistance and durability;
Rotating probes are suitable for products that require quick connection and disconnection between the two ends of a spring pin. Since both ends can mate with the PCB and the mating component, there is no need to solder one end, allowing for flexible mating. This makes them ideal for housing‑type connectors that do not require soldering, such as watch housings and speaker housings in mobile phones. During the assembly process, different springs must be installed inside the tube in two separate steps, which increases the number of assembly operations for both the springs and the tubing. In mass production, adding an extra step to install a single spring can reduce overall throughput.
The foregoing describes the advantages of the rotary probe: the dual‑head probe comprises a tubular body and two pins mounted at its ends, with through‑holes extending along the length of the body. A spring is fitted within these through‑holes, with each end of the spring abutting one of the pins, thereby enabling a single spring to be inserted into the socket. Moreover, because the probe features a tubular design, it offers benefits such as reduced connector material and weight, lower costs, and easier handling and connection.
