1. Superior insertion performance
By smoothing process after electroplating, smoothness of the flat surface, plating thickness uniformity of the corner part and good insertion performance to connector elements and print circuit boards are provided.
2. Low and stable contact resistance
By combination with the sharp corner of square wire and tin layer of low contact resistance, reliable contact performance is provided.
3. Superior soldering performance
Good soldering performance is provided, because of the undercoating layer between tin plating layer and brass wire made of nickel or copper to prevent metallic diffusion and smoothness of the surface.
4. Whisker prevention
The occurrence of whisker is inhibited and an unexpected short circuit accident is prevented by reflow process and smoothing process to the tin plating layer.
