Disclosed is a supporting mechanism for a work panel at through hole forming process by laser drilling. When laser energy reaches the supporting panel on stage of laser drill machine after forming the through hole, the supporting material is decomposed by the laser energy and adhered to the work panel surface and through hole barrel as contamination. This invention disclosure provides the mechanism to prevent the work panel from contamination.
