Abstract:
A method for joining wiring boards, the method comprising:providing first and second non-conductive wiring boards, both wiring boards being made up of a resin material, and both wiring boards being respectively covered with a conductive pattern; placing said first and second non-conductive wiring boards together in a face-to-face relationship such that a first predetermined portion of said conductive pattern covering said first wiring board is facing a second predetermined portion of said conductive pattern covering said second wiring board; positioning the first and second predetermined portions between first and second welding surfaces of an ultrasonic welding tool; applying an ultrasonic vibration to said first and second welding surfaces to weld the first and second predetermined portions of said respective conductive patterns, thereby creating a conductive bond therebetween; exposing at least a portion of at least one of said first and second non-conductive wiring boards as a result of said act of applying an ultrasonic vibration; and welding at least a portion of said first non-conductive wiring board to said second non-conductive wiring board, thereby creating a mechanical bond between said wiring boards in addition to said conductive bond.
