Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a punching device for processing circuit boards. Background Art

[0002] A circuit board, or PCB, is primarily composed of pads, vias, mounting holes, conductors, components, connectors, fillers, and electrical boundaries. PCBs miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. During the PCB manufacturing process, numerous and densely packed through-holes are required.

[0003] Existing circuit board punching equipment usually requires operators to manually place the circuit board into the punching equipment. The operation process has low safety and efficiency, and lacks a clamping means. During the punching process, the circuit board is prone to deviation in the punching position due to displacement of the circuit board, affecting the subsequent use process and failing to meet people's usage needs. For this reason, we propose a punching equipment for processing circuit boards. Utility Model Content
