Abstract: This invention relates to a process for machining resin film for a wiring board or double-sided carrier tape which comprises forming openings in the resin film by applying a continuous-wave carbon dioxide gas laser beam which is scanned in one or two ways to the resin film or a laminate containing a layer of the resin film placed on a worktable (5) moving in the direction nearly at a right angle to the scanning direction of the laser beam (7). As a continuous-wave carbon dioxide gas laser beam is used for drilling holes, the operation is highly efficient and accurate and gives rigid-flex wiring boards or double-sided carrier tapes of good quality in high yield.
