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.
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
