Custom Metal Etching Lead Frames with Tight Tolerances for Advanced Sensor and MEMS Applications

Lead Frames Overview
Xinhaisen Technology is a leading manufacturer of high-precision etched lead frames for semiconductor packaging, ICs, LEDs, and power electronics. Our chemically etched lead frames offer superior dimensional accuracy, excellent conductivity, and reliable performance for advanced electronic applications. With state-of-the-art etching technology, we ensure tight tolerances, burr-free edges, and cost-effective solutions for both prototyping and mass production.

Manufacturing Process
We utilize state-of-the-art chemical etching (photochemical machining) to produce lead frames with fine features and tight tolerances. The process involves:

• Material cleaning and pretreatment

• Photoresist coating and UV exposure using high-precision tooling

• Controlled chemical etching to form precise geometries

• Thorough cleaning, inspection, and quality verification

This method allows for burr-free, stress-free production without altering material properties, enabling complex designs with rapid turnaround.

Lead Frames Features

• High Precision: Micro-features with line widths down to 0.015mm and positional accuracy within ±0.03mm

• Wide Material Compatibility: Supports copper alloys, stainless steel, aluminum, nickel alloys, and more

• Burr-Free & Stress-Free: No mechanical deformation, ensuring optimal electrical and thermal performance

• Design Flexibility: Rapid prototyping and customization for complex geometries

• Scalable Production: Efficient handling of both small batches and high-volume orders
