ABSTRACT:
A control system for a blind microwave radiation tool a workpiece is described. The controlled system automatically tunes the cavity containing the workpiece. The control system automatically controls the temperature of the workpiece according to a predetermined temperature versus time schedule. Control system automatically determines when the workpiece has reached a particular predetermined physical condition. To achieve these results the control system automatically monitors applied power, reflected power or current temperature and automatically controls the microwave cavity volume and shape and launch structure including antennae location, cavity short location, cavity diameter, coupling loop position, etc. in order to maintain the cavity in resonance and to determine when to exit without operator intervention. Control system can run on a small computer or an embedded controller and is useful for automatically curing polyamic acid to polyimide to a predetermined percent cure, processing preimpregnated glass cloth in a continuous manner which can be used in circuit boards and drying and partial curing of web-like materials automatically without operator intervention.
