Abstract
The invention is to an apparatus and method for applying a plastic material to a lead frame for stabilizing the leads and retaining them in a common plane.
Claims3
A apparatus for applying material to lead frames to stabilize lead frame leads, comprising:
- a support base on which to align a lead frame and the applied stabilizing material;
- a carrier base for supporting the applied stabilizing material, the carrier base is positioned between the support base and the lead frame;
- a heater block for applying heat to the lead frame and stabilizing material;
- and
- a press for creating pressure to the lead frame and stabilizing material between the support base and heater block.
