Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of copper foil repair of copper-clad substrates and relates to a jig for repairing edge defects of the copper foil of a substrate. Background Art
[0002] Copper clad laminate, also known as copper foil substrate, is the basic material of the electronics industry and is mainly used for processing and manufacturing PCB printed circuit boards. It provides a conductive layer and insulation support for electrical connections, laying the foundation for the birth of PCB printed circuit boards.
[0003] Currently, copper foil substrates undergo a press-brazing process, which can cause solder overflow, solder diffusion, and edge defects on the substrate's copper foil. Manual polishing is usually performed using a small pneumatic grinding pen. However, manual polishing with a pneumatic grinding pen is inefficient and prone to uneven polishing and non-uniform margins, affecting the actual use of the product. Utility Model Content
[0004] In response to the above-mentioned problems existing in the prior art, the present application provides a jig for repairing edge defects of substrate copper foil.
[0005] The technical solution of the utility model is as follows:
[0006] A jig for repairing edge defects of copper foil of a substrate comprises a sliding guide rail, the sliding guide rail is equipped with a slider, a grinding pen is installed on the top of the slider, and a grinding head is provided on the top of the grinding pen. The grinding pen and the slider move back and forth on the sliding guide rail. The substrate to be processed is placed on a platform, and the substrate to be processed is positioned by the cooperation of a first positioning plate and a second positioning plate. The platform is positioned on a positioning block by a fixing screw, and the height of the platform is adjusted by a top screw so that the grinding head and the substrate to be processed maintain an appropriate height. The substrate to be processed is turned by adjusting the first positioning plate and the second positioning plate, so as to process each edge of the substrate to be processed.
[0007] As a preferred embodiment of the present invention, there are two groups of sliding guide rails.
[0008] As a preferred embodiment of the present invention, the number of the top screws is four.
[0009] As a preferred embodiment of the present invention, the number of fixing screws is four.
[0010] As a preferred embodiment of the present invention, the widths of the first positioning plate and the second positioning plate are equal.
[0011] The beneficial effects of the utility model are:
[0012] The utility model discloses a jig for repairing edge defects of copper foil of substrate. The sliding guide rail is used to realize forward and backward operation, the consistency of the width of the polished edge is guaranteed, and the polishing depth is controllable. By adjusting the height of the positioning block and the platform, substrates to be processed with different specifications and lengths can be processed; the manual polishing alignment process is omitted, and batch operations of the same specifications can be carried out through the positioning of the jig; the operation is effectively controlled, avoiding manual visual operation, and can ensure the effective distance of the polishing margin, polishing is smooth and the margin is made uniform, which is convenient and efficient.
