1. A printed circuit manufacturing system for applying a mounting material to a substrate, the system comprising
a blade unit having a blade element elongated along a first axis and having a thickness along a transverse second axis and selectively movable along at least each of the first and second axes, wherein the blade element, during such movement along the second axis, transfers the mounting material to the substrate, a reciprocating motor coupled to the blade unit for reciprocating the blade element along the first axis concurrent with movement of the blade element along the second axis, a vibration detector coupled to the blade unit for detecting the vibrational movement of the blade element, wherein the vibration detector generates an output signal corresponding to the vibrational movement of the blade element, an air control unit coupled to the reciprocating motor for adjusting the amount of air pressure supplied to the motor, and a control unit coupled to the vibration detector and to the air control unit for generating an output signal in response to the output signal of the vibration detector to control the air control unit, wherein the air control unit in response to the output signal of the control unit adjusts a frequency of vibration of the reciprocating motor by controlling the air pressure supplied to the reciprocating motor. |
