PROBLEM TO BE SOLVED: To provide a setting method of laser drilling working conditions and a laser working machine which reduces a change of a parameter requiring experience and skill, confirms a hole shape without removing a substrate and does not require manual input of each parameter of optimum conditions.SOLUTION: Test areas are provided on at least five portions of a center part and four corner parts of a working area, a set of at least 16 pieces of holes is worked on each test area, and optimal drilling working conditions are selected by comparing hole diameter, hole shape and hole position of a hole formed on the same working conditions of each test area with those of a hole formed by other working conditions.SELECTED DRAWING: Figure 2 |
