How Can The Adhesion Of Cold-pressed Needles Achieve Long-term Stability?

The design of the crimp contact pin causes it to elastically deform when inserted into a PCB hole, forming a tight metal contact layer by means of the contact force between the pin and the hole wall. This contact exhibits almost no thermal stress from the presence of solder and avoids material fatigue caused by thermal cycling, thus improving the continuity and stability of the connection. The mechanical fit between the contact socket crimp and the PCB not only results in low and stable resistance, but also reduces the impact of vibration and mechanical shock on the contact interface.

In actual manufacturing processes, the omission of high-temperature soldering steps and the cold pressing process avoid stress differences between thermally expanding materials, stresses that are often the source of loosening or even breakage in traditional soldered connections. The crimp contact female has precise insertion force control, and its spring characteristics can maintain sufficient contact pressure at the connection point after insertion, so that the connection can maintain structural and electrical stability even after long-term use.
