High-power UV laser cutting technology to avoid PCB circuit board burrs

In general, the surface of metal parts and the surface of small microscopic metal particles appear, these are called burrs. The more burrs, the lower the yield of PCB circuit boards.

Causes of burrs: The cutting edge becomes dull and the gap is too large; the saw blade is dull or improperly installed; the punch is worn or improperly installed; the flame cutting operation is improper; the welding system is not standardized, etc.

In order to solve the PCB burr problem, RFH Seiko has 13 years of special research and development and production by foreign professors and doctoral teams. The 15W high-power ultraviolet laser has the characteristics of low thermal impact, ±0.01mm high precision, and high power stability. When the board is cut, punched, and engraved, it can effectively avoid the generation of burrs, and the cut is clean and smooth, without burrs, and no dust particles, so it is widely used in the PCB and FPC circuit boa
