Abstract
812,772. Moulding printed circuits. ERIE RESISTOR CORPORATION. Sept. 26, 1956 [Oct. 10, 1955; Nov. 7, 1955], No. 29405/56. Addition to 725,115. Class 87(2). [Also in Groups VIII and XXXVI] In a method of making a printed circuit as described in the parent Specification in which a metal foil sheet is united to an uncured resin-impregnated laminate under heat and pressure to mould the laminate to a desired form, cause the metal foil to adhere thereto and effect the curing thereof, holes extending wholly or partly through the laminate are formed where required during the moulding process. Fig. 4 illustrates the resultant form of the laminate and attached metal foil after moulding between heated dies as shown in Fig. 3. By grinding away the upper surface of the laminate at the level 19, the desired circuit configuration is obtained ; while by removing its lower surface at the level 20, the hole partly formed during the moulding is completed. Figs. 5 and 6 (not shown) illustrate a modified arrangement in which the form of the die is such that the hole is completely formed during the moulding operation.
