| For semi-conductor application, the complete production line includes sub-micron tooling design and manufacture, super accuracy 2μm high speed press and stamping technology of lead frame, Pd (palladium), Ag multiple metal-plated and accurate injection molds. The LED related application, such as automotive, TFT-LCD display, general illumination and etc is famous now. |
|
| After first stamping of lead frame at 45 – 60tons press and plastic injection, the strip requires second stamping (forming) process |
|
| |
|
 |
The micron-grade of stamping technology should be applied for the quality of products with cutting, bending, curling and coining process. |
 |
power transistor (hybrid IC), thick material stamping including coining process at 80 – 200 tons press. |

| During eccentric loading from tooling stamping, the parallelism between slide and bolster is changing. Apex-Knuckle press deformation is 1/3 of other crank presses. (JIS special grade require 0.07mm at parallelism without eccentric loading.) |
