Precise Lead Frame Manufacturer

Application Industries:
● Electronics
● Telecommunications
● Recreational
● Industrial Controls
● Aerospace
● Avionics
● Lighting
● Isemi-conductor
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  
sheet metal punch The micron-grade of stamping technology should be applied for the quality of products with cutting, bending, curling and coining process. sheet metal cutter Power transistor (hybrid IC), thick material stamping including coining process at 80 – 200 tons press.

Quality of Dynamic Stamping

Precise Lead Frame - Quality of Dynamic Stamping Above 1mm to BDC, the period is double of crank presses to match super grade forming and coining process’s requirement.
At 1,000 strokes, the BDC deviation is only ±2.5μm to match super accuracy requirement. Precise Lead Frame - Quality of Dynamic Stamping
Precise Lead Frame - Quality of Dynamic Stamping Warm up the press by thermostatic system to keep the BDC deviation within 0.03mm at the first running hour.
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.) Precise Lead Frame - Quality of Dynamic Stamping Precise Lead Frame - Quality of Dynamic Stamping
