Abstract:
A continuous assembly system comprising:means for transporting a lead frame in the form of a reel of tape along a transport path, the lead frame having a plurality of leads each having an inner lead portion connected to a support member for supporting a semiconductor chip;means for adhering a semiconductor chip having a plurality of electrodes on one main surface thereof to the support member at another main surface opposite to the one main surface, said means for adhering being disposed at a first position of the transport path;means for connecting the plurality of electrodes via a plurality of bonding wires to corresponding inner lead portions of the plurality of leads, said means for connecting being disposed at a second position of the transport path more downstream than the means for adhering;means for forming an insulating layer as protective coating, the insulating layer covering a top surface of an assembly unit including the semiconductor chip, the plurality of bonding wires, the support member, and the inner lead portions of the plurality of leads, said means for forming an insulating layer being disposed at a third position of the transport path more downstream than the means for connecting; andmeans for separating the inner lead portion of each lead among the plurality of leads from the supporting member, at a position between the support member and a contact area of the bonding wire to the inner lead portion under the condition that the top surface of the assembly unit is covered with the insulating layer, said means for separating being disposed at a fourth position of the transport path more downstream than the third position.
