[Also in Division B5] To avoid misalignment of the terminal connectors of electric circuit modules having flat substrates, each connector is formed from wire of semi-circular cross-section bent into U-form and a contact portion on the substrate 9 is soldered between the flat sides of the U, the remaining parts of the U being pressed together to form a circular cross-section terminal connector 11 which may be inserted in sockets in a printed circuit board or other base. The module may be encapsulated, after first spraying the substrate with a protective coating, by inserting the terminal connectors 11 in holes in a removable base 13 (Fig. 8) of a die 12 and compressing heated plastics moulding material in the die with a plunger 14 until the plastics has cured. Alternatively the module may be encapsulated by known dipping methods.
