영문 초록

FPCB (Flexible Printed Circuit Board) cutting by femtosecond laser was performed to make clean, debrisless, accurate cutting. We put 3 kHz, 300mW femtosecond pulse laser with 3 mm/s velocity, where center wavelength is 775 mm, and clean cutting was produced. No electro-shorting was occurred. No unwanted material damage is shown.
