SETTING METHOD OF LASER DRILLING WORKING CONDITION AND LASER WORKING MACHINE

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 【課題】本発明の目的は、経験と熟練が必要なパラメータの変更を軽減し、基板を取り外すことなく穴形状を確認し、最適条件の各パラメータを手入力する必要のないレーザ穴あけ加工条件の設定方法及びレーザ加工機を提供することにある。【解決手段】少なくとも、加工エリアの中心部、四隅部の５か所にテスト領域を設け、各テスト領域に加工条件の異なる１６個以上の穴の組を加工し、各テスト領域の同一の加工条件で形成した穴の穴径、穴形状、穴位置を他の加工条件で形成した穴のものと比較して最適な穴あけ加工条件を選定する。【選択図】図２
