METHOD FOR MANUFACTURING RESISTOR FOIL STRAIN GAGE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a resistor foil strain gage, for eliminating such problems that in manufacturing a strain gage using an electric resistor foil, accuracy of a designed pattern degrades by repetition of exposure and development and that the number of processes for managing or producing a screen or a mask cannot be reduced.;SOLUTION: A strain gage is manufactured by exposing a photoresist applied to a resistor foil 3 adhered on an insulating film to laser irradiation from a laser generator 5 without preparing a screen or a mask, and then etching the resist.;COPYRIGHT: (C)2015,JPO&INPIT
