Spade width
Spade width is specified in millimeters and describes the width of a spade-shaped Tip style at the contact tip of a Contact Probe. It influences the size of the contact area and thus the current-carrying capacity, contact stability, and mechanical stress at the Test Point. The appropriate spade width is adapted to the geometry and surface of the Test Point to ensure reliable and reproducible electrical contact.
FAQ
It influences the current carrying capacity, contact stability, and mechanical load at the Test Point.
It is adapted to the geometry, surface, and mechanical requirements of the Test Point to ensure reliable electrical contact.
A wider spade width distributes the spring force over a larger area, thereby reducing the mechanical stress at the Test Point, while a narrower spade width can allow for higher surface pressure and deeper penetration into oxide layers.
