Embodiment Construction

[0013] The present invention provides a cover plate for PCB drilling. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] figure 1 It is a structural diagram of a preferred embodiment of a PCB drilling cover plate of the present invention, as shown in the figure, it includes an original cover plate 1 and an adhesive resin layer 2 coated on the back of the original cover plate 1 . In the present invention, an adhesive resin layer is added to the back of the original cover plate 1 (that is, the traditional cover plate). The ridges that should appear on the surface of the PCB board are transferred to the surface of the cover plate, so that there is no ridge on the surface of the PCB board, and the gap b...

Abstract

The invention discloses a cover plate for PCB drilling. The cover plate comprises an original cover plate and an adhesive resin layer on the back of the original cover plate. According to the cover plate for PCB drilling, the back of the original cover plate is added with the adhesive resin layer, accordingly, the cover plate can be firmly attached to the surface of a to-be-drilled PCB plate in the using process, a clearance between the cover plate and the to-be-drilled PCB plate is prevented from being produced, and the cover plate and the to-be-drilled PCB plate are integrally formed. Burr to be appeared on the surface of the PCB plate is transferred to be on the surface of the cover plate, and the clearance between the cover plate and the PCB plate is prevented from being produced; accordingly, the hole position precision is improved, the chip discharging effect is improved, and meanwhile the cover plate is inhibited from moving relatively on the surface of the PCB plate.

Description

technical field [0001] The invention relates to the field of cover plates, in particular to a cover plate for PCB drilling. Background technique [0002] The cover plates used before are naturally placed on the surface of the PCB board to be drilled, and fixed with clamps or with masking tape around them. There will inevitably be a gap between the traditional cover plate and the PCB board, and the following problems will occur during the drilling process: (1) The gap will cause the copper foil on the surface of the PCB board to be lifted when the drill needle is lifted, forming a larger (2) The existence of the gap will cause uneven resistance to the drill needle when it enters the drill, and the deviation will occur, and the hole position accuracy will be reduced; (3) The existence of the gap will cause the cover plate and the The relative movement of the PCB board affects the drilling efficiency; (4) Part of the powder chips will be sucked into the gap during the drilling...
