A METHOD FOR THICKNESS MEASUREMENT OF DIPPING COATING LAYER ON WIRE

摘要

A method for measuring dip-coating thickness of a wire is provided to secure the uniformity of dip-coating and control the dip-coating thickness in the wire manufacturing process. A method for measuring dip-coating thickness of a wire includes a step(110) for coating dipping solution on the wire surface, a re-coating step(120) for forming a platinum(Pt) or tungsten(W) coating layer by using ion beam sputtering deposition(IBS/e) coating equipment in order to classify the coating layer before measuring the dip-coating thickness of the wire, a section step(130) for making a sample for coating thickness measurement of the re-coated wire, and a step(140) for measuring the coating thickness of the sample by using the TEM(Transmission Electron Microscope).
