Photo Chemical Etching Micro Etched Lead Frames with Customized Materials

Lead Frames Overview

Xinhaisen Technology specializes in manufacturing precision-etched lead frames for semiconductor and microelectronics packaging. Our lead frames serve as the critical interconnection platform for IC chips, providing superior electrical conductivity, heat dissipation, and mechanical stability. Utilizing advanced chemical etching technology, we deliver products with unmatched dimensional accuracy for applications in QFN, DFN, SOP, SSOP and other advanced packaging formats.

Lead Frames Features

• Burr-Free & Stress-Free: The etching process creates smooth edges without the mechanical stress or burrs common in stamped parts, preventing delamination and improving reliability.

• Design Flexibility: Easy and cost-effective to iterate complex designs, fine pitches, and custom geometries without the high cost of hard stamping dies.

• High Precision & Consistency: Achieves exceptional accuracy for fine-pitch applications and ensures uniform quality across large production batches.

• Material Versatility: Capable of processing a wide range of alloys, including high-conductivity copper (C194, KLF-1), low-CTE Alloy 42, and Kovar.

• Rapid Prototyping: Significantly faster lead time for prototypes and pre-production samples compared to traditional methods.
