It is of great difficulty for conventional techniques to machine brittle and hard materials. As one of nontraditional machining methods, laser beam machining has emerged as an effective technique for drilling of ceramics. This paper reviews the research work on laser drilling of structural ceramics from its different pulse width.
Furthermore, the chemical inertness impedes an efficient chemical processing which is standard in FR4 processing. Hence, laser drilling has been established as a standard ceramic processing method.

Trepan or Helical Drilling For the research on picosecond laser drilling in ceramic materials, in 2013, Wang et al. used a 1 ps (1030 nm, 100 kHz) laser to drill a blind hole and used a 10 ps (532 nm, 20 W) to drill a through hole in C f /SiC with a thickness of 3 mm.
Zhang et al. [49] have performed the fs laser drilling of TiC ceramic by helical drilling in air. Their study indicated that depth of hole increased and decreased then with the increase of laser energy density at the value 0.51 J/mm 2. Higher energy density was conducive to eliminating the parallel grooves on the surface of TiC.
