SUPPORT AND TRANSPORT UNIT FOR A PRINT SUBSTRATE FOR A PLANT FOR DEPOSITING PRINT TRACKS , AND RELATIVE DEPOSITION METHOD

摘要

PURPOSE: A PCB supporting and carrying unit in a print track depositing plant, and a deposition method thereof are provided to control the filling level of a hole by adjusting the level with a metal inside the hole. CONSTITUTION: A PCB(12) contains extended holes(57) through a first surface(55) and a second surface(56). A first fluid dynamic circuit is prepared to generate a first suction state at one or more first areas on a supporting surface(113) of a supporting plate in order to keep the PCB attached to the supporting surface of a supporting unit. A second fluid dynamic circuit(33) is prepared to generate a second suction state at one or more second areas on the supporting surface of the supporting plate. The one or more second areas are arranged to be connected with one or more holes of the PCB.
