High-Precision Etching Multi-Material Lead Frames for Semiconductor and Automotive Electronics

Lead Frames Overview

We specialize in manufacturing high-precision lead frames using advanced metal etching technology. Our lead frames are essential components in semiconductor packaging, providing reliable electrical connectivity and heat dissipation for integrated circuits (ICs).

Manufacturing Process
Our lead frames are produced through precision chemical etching, which allows for burr-free, stress-free, and highly accurate results without altering the material properties.

Lead Frames Features

• Exceptional Precision: Capable of ultra-fine features, with minimum line widths down to 0.015mm and micro-hole diameters as small as 0.03mm.

• Superior Consistency: High etching uniformity (±0.03mm) ensures every part meets strict dimensional tolerances for reliable performance.

• Material Versatility: We process a wide range of metals, including Copper, Alloy 42, Kovar, and various stainless steels.

• Burr-Free & Stress-Free: The etching process produces smooth edges without mechanical stress, preventing damage to delicate chips.

• Complex Design Capability: Easily accommodates intricate and fine-pitch patterns that are challenging with other methods.
