METHOD OF ASSEMBLING A PERSONAL CARE PRODUCT

摘要

A method of assembling a heating element (16) for a shaving razor (10) by providing an insulating member (42) having a base (74) with a plurality of spaced apart electrical terminals (60). A flexible printed circuit board (34) having a plurality of spaced apart electrical terminals (54) is provided. The electrical terminals of the insulating member are soldered to the corresponding electrical terminals of the flexible printed circuit board. A liquid non electrically conductive underfiller encapsulant (72) is dispensed between the base of the insulating member and the base (76) of the flexible printed circuit board forming a water tight seal between each of the spaced apart electrical terminals of the insulating member and between each of the electrical terminals of the flexible printed circuit board by curing the liquid non electrically conductive underfiller encapsulant.
