Method of peeling a bonded film from a circuit board
摘要:
An apparatus for bonding a multi-layer thin film onto a substrate and for removing a layer of the film. A printed circuit board having a multi-layer film bonded to a planar surface thereof has one layer of the film lifted at a leading edge by vibration and fluid pressure. The leading edge is mechanically gripped and a pulling force applied thereto to draw the film from the surface of the circuit board and to transfer the removed film along a path to a discharge apparatus. The transfer apparatus includes frictionally engaged belts which direct the film along a transfer path to a source of ionized fluid which is applied to the film in order to remove static and direct the film along the transfer path towards a used film receptacle.
