General terminals with copper rolling surface matching terminal contact conduction, but when the connector reduced PITCH (such as PITCH =

1.0 mm or 0.5 mm), terminal may have to the shear plane as the conduction of the contact surface.

At that moment, shear faces for copper percentage and shear surface roughness will most likely be asked to achieve a high standard (e.g., 80% of the shear plane).

In the face of such shear plane problem, stamping in the mold design to use those methods, consider what condition to overcome?

Shear section introduces

Shear section:

(A) first as early embryo blanking section, local area reserved about (0.10 mm, 0.06 mm, 0.04 mm) material width.

(B) feed section further refinement.

To be seen:

(1) for discharging the reserved material width of early embryo size, the influence of shear percentage after finishing.

(2) the shear clearance of refinement to the influence of two of the following features: - after finishing the integrity of the residues. - percent of thickness shear plane.

(3) the refinement punch local area for polishing processing, to improve the terminal shear effect of surface roughness.
