Abstract

PURPOSE: To obtain a sure waterproof and moisture proof effect with a simple construction by molding conducting patterns formed on a board except the parts of the patterns for measuring electrodes and soldered positions with thermoplastic synthetic resin.
CONSTITUTION: On one surface of a printed board 58, conducting patterns on which electronic parts 59W61 are to be attached are formed of a copper foil or the like. An upper metal mold 56 and a lower metal mold 57 constitute female and male metal mold cavities. By forming the cavities so that synthetic resin may not be injected to portions corresponding to the electronic parts 59W61 which are to be fixed to the printed board 58 using these metal molds, or measuring electrodes and through holes, and carrying out injection molding to the printed board, a molded board is obtained. By so doing, insulation between the conducting patterns can be made perfect and sure waterproof and moisture proof effect can be obtained with a simple construction.
