Core Product Portfolio

Interactive Segment Filter:

Integrated Circuit (IC) Lead Frames

SOP, DIP, QFP Series

High-density structural configurations tailored to secure silicon dies and deliver pristine connection profiles across standard multi-pin package arrays like Small Outline Packages (SOP) and Dual In-line Packages (DIP).

Discrete Device Frames

SOT, TO-92, TO-126 Series

Specially stabilized copper architectures manufactured to match exact mechanical footprints for foundational discrete components including transistors, small-signal diodes, and standard SOT surface-mount form factors.

Power Series Lead Frames

TO-220, TO-247, TO-3P, TO-263

Heavy-duty layouts structurally optimized with thick copper frames and maximized thermal conductive paths to support high-voltage power modules like MOSFETs, IGBTs, and thyristors.

Etched Ultra-Fine Pitch Series

QFN, DFN, Fine-Pitch Matrix

Engineered via chemical subtraction processes instead of mechanical punches, allowing ultra-thin profiles, matrix layouts, and tight pad margins required for high-density QFN/DFN chip architectures.

Advanced Manufacturing Capabilities

TOOLING DEVELOPMENT

In-House Progressive Die Fabrication

Independent construction and maintenance of high-precision dynamic progressive stamping tools, giving electronics manufacturers rapid customization channels and custom design adaptability.

STAMPING BAY

Automated Multi-Station Stamping

High-speed manufacturing facilities fitted with specialized high-tonnage automated pressing units, ensuring low defect rates across massive corporate supply allocations.

SUBTRACTION

Precision Chemical Etching Lines

Advanced chemical-mill pathways that safely render micrometer-level trace definitions without introducing stamp shear stresses onto delicate raw copper strips.

METALLIZATION

Selective Surface Electroplating

Highly targeted continuous functional plating capabilities (such as localized silver zone plating) to secure robust wire-bond interfaces and avoid packaging oxidization paths.
