Description

Technical Field

[0001] The invention relates to the technical field of circuit board drilling, in particular to a device for recovering copper powder from circuit board drilling powder. Background Art

[0002] Drilling powder will be produced when drilling holes in a circuit board. The ingredients of drilling powder generally include resin, glass fiber, copper powder, etc. The base material of the circuit board is usually composed of resin, such as epoxy resin. These resins will produce powder due to friction and cutting during the drilling process. In addition, in order to increase the strength and stability of the circuit board, glass fiber is usually added. When drilling, the glass fiber is cut and broken to form glass fiber powder. When drilling, the copper foil layer on the circuit board will produce copper powder. The content of copper powder in the drilling powder depends on the thickness of the copper foil of the circuit board and the process parameters of the drilling. Copper powder is usually in the form of fine particles, reddish brown or purple-red in color, and has good conductivity.

[0003] After proper treatment and purification, the recycled copper powder can be used as the raw material for producing copper foil for circuit boards. During the copper foil manufacturing process, the copper powder is melted and made into thin copper foil through a specific process, which is used for the conductive layer of the circuit board. In addition, the recycled copper powder can also be used to manufacture other electronic components. The recycled copper powder is processed into thin wires or connectors, which can be used for circuit connections inside electronic devices. In the manufacture of inductors and transformers, copper coils are one of the key components, and the recycled copper powder can be used to make copper coils. The existing circuit board drilling process requires the circuit board to be fixed on the pad first, and the circuit board can be penetrated when drilling. At this time, the drill rod will cut the pad and produce excess dust. When the circuit board is placed on a hollow support table with a hole in the middle, the drill rod can penetrate the circuit board, but due to insufficient support force, the circuit board will be squeezed and deformed during drilling.
