Drill needle for FPC board

Abstract

The invention discloses a drill needle for an FPC board. The drill needle for the FPC board comprises a needle handle, wherein a needle head mounting base is welded to one end of the needle handle; and a threaded hole is formed in the middle position of the needle head mounting base, a positioning groove is formed in the outer wall of one side, far away from the needle handle, of the needle head mounting base, and a mounting hole is formed in the position, located on one side of the positioning groove, inside the needle head mounting base. According to the drill needle for the FPC board, the needle handle, a needle head, a positioning ring, the needle head mounting base, a fixed screw rod, the positioning groove, the threaded hole and an unlocking button are arranged; when the needle headis installed, the needle head is fixed on one side of the needle head mounting base through the fixed screw rod and the positioning ring, the needle head mounting base is welded to one end of the needle handle, so that the connection between the needle handle and the needle head is completed, and the positioning ring and the fixed screw rod are used for enabling the needle head and the needle headmounting base to be effectively fixed; and meanwhile, the installation position of the needle head can be effectively limited by a lock rod in the positioning ring, the phenomenon that the needle head of the drill needle is loosened in the rotating process is avoided, and therefore the fixation stability of the needle head is ensured.

Description

technical field [0001] The invention belongs to the technical field of flexible circuit boards, and in particular relates to a drill for an FPC board. Background technique [0002] Flexible printed circuit board (FPC for short) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film, with high wiring density, light weight, thick Thin and flexible. [0003] However, drills of various sizes and specifications are required in FPC processing, and the existing drills are inconvenient to replace the needle handle and needle head separately during use, resulting in low replacement efficiency, and the installation structure of the drills is not enough It is stable, and it is easy to cause the drill pin to deviate, resulting in damage to the FPC board. In addition, the polyimide in the existing FPC board has high viscosity, and the powder generated during the drilling of the FPC board is easy to contact with the surface of the drill pin....
