Abstract:
A method for processing resin sealed lead frames by performing a first number N of processing operations on said resin sealed lead frames, said method comprising the following steps:(a) preparing said resin sealed lead frames with products (2) on said resin sealed lead frames (4) having a spacing corresponding to a first pitch (P) defined as an on-center distance between neighboring products (2) on said resin sealed lead frames (4),(b) assembling a second number n of processing tool modules (100, 101, . . . ) for each of said first number N of processing operations, in series along a processing feed advance path, so that a total number M of processing tool modules corresponds to M=N.multidot.n for performing said operations on said resin sealed lead frames, and(c) sequentially feeding said resin sealed lead frames with said products on said resin sealed lead frames (4) along said processing feed advance path in steps having a step length corresponding to a second pitch (P') that is equal in length to said second number n times said first pitch (P), thus P'=n.multidot.P, and wherein said second number n is at least equal to two for simultaneously processing at least two of said products on said resin sealed lead frames.
