apart the terminal pins 12 of an electrical component 10 before the component is mounted on a printed circuit board 16 the component is placed in a guide body 18 which has pin guide sockets 32 with funnel like mouths through which the pins pass to be guided through apertures 36 which are offset to different sides of an imaginary median line of the sockets application_number US 13390998 A description fig1 shows a conventional liquid crystal display panel 10 hereinafter referred to as a 34 lcd panel 34 with eleven parallel pins 12 extending from one edge the pins can be for example 40 mm long the pins all extend in one plane and their ends 14 are at this stage free and are not restrained in any way other than by the rigidity of the metal from which they are made although eleven pins are shown in fig1 it will be understood that the number of pins actually present will depend on the number of functions to be displayed on the lcd panel 10 and therefore there may be a greater or lesser number than eleven indeed panels with different numbers of pins are shown in the accompanying drawings in fact in one particular embodiment there were twenty two pins spaced apart with a pitch of 1 8 mm the pins are conveniently of rectangular cross section with the major dimension of the pin cross section lying in the plane of the pins.
