AI Technical Summary
During the FPC laser cutting process, the honeycomb plate vaporization produces black smoke and reverses the FPC surface, resulting in laser dirt and poorness.
An FPC laser cutting system is designed, which includes CNC-processed cutting grooves and first through holes on the carrier plate of the laser machine table to prevent laser energy from hitting the honeycomb board.
It effectively prevents the black smoke generated by the gasification of the honeycomb panel from sticking to the FPC surface, preventing laser contamination and defects.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to FPC laser cutting, and in particular to an FPC laser cutting system. Background Art
[0002] When FPC uses laser drilling for the first through hole, the product is usually placed directly on the machine for processing.

Therefore, after the first through hole is laser drilled, there will be excess laser energy hitting the honeycomb board. After the honeycomb board is vaporized, a large amount of black smoke is produced, which in turn sticks to the surface of the FPC, causing laser contamination and resulting in laser defects.
