Method of manufacturing continuous strip of electronic devices

A method of manufacturing of continuous strip of electronic devices comprising the steps of:

• forming a first interconnected strip carrying a plurality of small size electronic devices having at least one terminal, said strip comprising a grid-like conductor strip member of a belt-like shape as a whole including a plurality of preassigned mount locations provided at a predetermined pitch along a center line of said grid-like conductor strip member and designated for mounting thereon small size electronic devices, and a plurality of conductors extending from each of said preassigned mount locations to both sides of said grid-like conductor strip member, said conductors having respective one end portions positioned closely to one another adjacent to the associated one of said mount locations, said end portions being used for connecting said at least one terminal of said electronic devices, those of said conductors extending to one side of said grid-like conductor strip member being connected to one another in the longitudinal direction with those conductors extending to the other side of said conductor strip member being connected to one another in the longitudinal direction;
• molding a first plastic strip segment including molded bodies formed integrally with said grid-like conductor strip member at said preassigned mount locations, respectively, each of said molded bodies having an opening portion at which said end portions of said conductors are exposed and which is used for assembling said electronic device therein, a runner member formed integrally with said molded bodies so as to interconnect said molded bodies, and a connecting portion formed at least at one end of said plastic strip segment at a predetermined position;
• shifting said first plastic strip segment by a predetermined distance in the longitudinal direction;
• placing a second interconnected strip formed in the same way as said first interconnected strip;
• and
• molding a second plastic strip segment which is the same as the first plastic strip segment upon said second interconnected strip, while connecting said connecting portion of said first plastic strip segment with one end of said second plastic strip segment, wherein said predetermined position of said connecting portion is such that the distance between said preassigned mount locations for the small size electronic devices positioned on both sides of said connecting portion coincides with said predetermined pitch.
