Apparatus for carrying a plurality of lead frames during processes for plating the lead frames, which comprises:
- a rack and a conductive hoist flight bar;
- said rack including:
- a rack body having the lead frames removably loaded there into;
- at least two latch bars which are connected to the rack body and are fixed to and detached from a hoist flight bar to which a plating electrode is electrically connected during plating of the lead frames;
- and
- an indexing means provided on said rack for positioning the rack and for positioning an apparatus for transferring the rack;
- the rack and hoist flight bar being such that the rack is removably hung from the hoist flight bar.
A system for plating lead frames, comprising:
- (A) an apparatus for loading lead frames, which comprises a rack into which a plurality of lead frames are removably loaded;
- a conductive hoist flight bar arranged to be removably connected mechanically and electrically to the rack;
- and a clamper for releasably fixing the rack to the conductive hoist flight bar;
- (B) a loading arm for loading and unloading the rack carrying lead frames to and from the clamper;
- (C) a line for loading lead frames to be plated into the rack and for unloading plated lead frames from the rack;
- (D) an unloading buffer for transferring the racks carrying plated lead frames from the loading arm to the line (C);
- and
- (E) a loading buffer for transferring the racks carrying lead frames to be plated from the line (C) to the loading arm.
