Double-ended probes are suitable for products that require quick access to
both ends of the split pin. Since both ends can be docked with the PCB and other
parts, the trouble of welding one end is saved, and the docking is flexible,
which is suitable for shell-type connectors that do not require welding, such as
watch shells and mobile phone sound shells. In the assembly process, different
springs need to be installed in the pipeline twice, and the equipment process of
the spring and the pipeline is increased. In the process of mass production, the
increase of the installation process of one spring will reduce the overall
output. Then, double-headed What are the advantages of the probe, let's take a
look!
The double-headed probe is a high-end precision electronic hardware
accessory, which is mainly composed of three parts: spring, needle tube and
needle tip. Also known as "spring pin", from the name, the spring pin must be
related to the spring, but it is not literally a needle made of a spring, this
is wrong, but there is a spring structure inside, which is very different from a
spring, that is Very sophisticated electronic accessories, which are powerful
and widely used, are mainly used in mobile phones, computers, communications,
etc. Almost all industries with chips are promoting the testing of the testing
industry using semiconductors. The main demand is the testing industry of chip
packaging.
Advantages of double-ended probes:
1. The coating of all parts is a patented formula of vacuum coating, hard
gold and hard nickel, thick gold and thick nickel: the coating is
wear-resistant, maintains stable resistance and excellent contact
conductivity;
2. The needle bar has heat treatment to increase the hardness and
toughness;
3. Meet the requirements of RHOS;
4. Small tolerance of needle tube and high hardness; Fatigue resistance of
spring;
5. Imported lathe: small tolerance, good gloss;
6. Precision assembly mold: the finished product shakes little and slides
smoothly;
7. Corrosion: to increase the adhesion of the coating; both ends of the
same detector;
8. Some different materials; different plating thicknesses. To ensure all
wear resistance, durability.
The advantages of the double-ended probe are described above. The
double-ended probe is characterized in that it has a tube body and two pins
arranged at both ends of the tube body, and has through holes penetrating the
tube body. A spring is arranged in the insertion hole, and both ends of the
spring are respectively in contact with the two pins. By adopting the
above-mentioned technique, it is clear that one spring is put into the socket
and two pins are held, and the assembly process of the spring and the tube body
is reduced compared to two springs. In addition, due to the tube body of the
socket, the material and weight of the connector are reduced, the cost is
reduced, and the transportation is convenient.
