Cross large flat head M2.0 circuit board grounding nail

The Cross large flat head M2.0 circuit board grounding nail is a mini screw designed for high-density PCBs. It has a diameter of 2.0 mm and a head enlarged to 4 mm. It can achieve low-impedance grounding on a 0.8 mm copper foil layer. The nickel-plated copper alloy body guarantees a contact resistance of 0.5 mΩ. The cross slot is compatible with automatic screwdrivers and can be locked with 0.12 N·m. It is a common micro screw solution for consumer electronics and communication base stations.   As a Precision screw, the thread accuracy is 6 g and the head flatness is ≤0.02 mm; the surface is passivated with trivalent chromium, and it does not rust after 96 hours of salt spray. The resistance change of the pre-coated conductive microcapsule glue after 10⁶ thermal cycles is <5%, ensuring long-term reliable grounding.   After passing ASTM F837 certification, the nail can be directly used as Aerospace Micro Screws for satellite power boards and drone flight control ground networks.…
