Custom Lead Frames Precision Etched Metal Frames for IC Semiconductor Packaging

What Is a Semiconductor Lead Frame?

A lead frame is a metal structure used in semiconductor packages to connect integrated circuits with external electrical connections.

Lead Frames Overview
Our etched lead frames provide critical connectivity and structural support for semiconductor devices. Using advanced chemical etching, we manufacture lead frames with exceptional dimensional stability and electrical performance, ensuring reliability in integrated circuits and microelectronic parts.

Manufacturing Process
We specialize in high-precision chemical etching, which enables stress-free, burr-free production of complex lead frame patterns without altering material properties. This method supports rapid prototyping and mass production with consistent quality.

Lead Frames Features

• Ultra-Precise Etching Capability: Achieves fine line widths down to 0.02mm and maintains tight tolerances of ±0.01mm, ensuring perfect alignment and connectivity for delicate semiconductor components.

• Excellent Electrical Performance: Manufactured from high-conductivity materials with optimized plating surfaces to ensure minimal signal loss and stable current transmission in high-frequency applications.

• Superior Thermal Management: Designed with optimal thermal expansion coefficients and heat dissipation properties to maintain performance stability under varying temperature conditions.

• Enhanced Mechanical Strength: Maintains excellent flatness and structural integrity during assembly processes, preventing deformation during molding and bonding operations.

• Clean Edge Quality: Burr-free edges and surfaces prevent micro-short circuits and contamination, crucial for high-reliability semiconductor applications.
