[0001] The utility model belongs to the field of circuit board processing, in particular to a circuit board processing jig. Background Art

[0002] Circuit board is one of the common basic components in electronic devices. It provides a platform for supporting, connecting and organizing electronic components. The main part of the circuit board is the substrate, which is usually made of insulating materials, such as glass fiber reinforced epoxy resin. The circuit board also contains other parts, such as conductive layer, solder mask, through hole, etc. The solder mask is a layer of insulating material covering the conductive layer, usually green. The solder mask is used to protect the circuit pattern and improve the insulation performance.

[0003] The solder mask coating is often performed after drilling, and the debris generated during drilling may interfere with the coating. The current circuit board processing jig requires manual cleaning of the debris on the circuit board surface and the through-hole after drilling, which reduces the continuity of the processing and results in low processing efficiency. For this reason, the present application proposes a circuit board processing jig. Utility Model Content
