Miniature Contact Spring for Autofocus Camera Module

Ultra-thin spring contacts often involve: Fine pitch structures Micro bending areas Tight tolerances Small radii Delicate conductive arms Without proper DFM evaluation, problems such as deformation, cracking, burrs, or assembly instability may occur more easily. We evaluate manufacturability before production to help improve process stability for miniature precision spring components.

Before production, we commonly review: Material selection Thickness suitability Spring geometry Compression direction Minimum feature size Bending radius Tolerance requirements Surface plating requirements Structural assembly feasibility For conductive spring contacts and precision flat springs, early evaluation helps reduce manufacturing and assembly risks.

For precision spring contacts and conductive flat springs, we control mass production consistency through: stable raw material sourcing, controlled process parameters, dimensional inspection, and production repeatability management. We pay close attention to: material thickness, spring geometry, burr level, flatness, and feature consistency to improve long-term stability across large production volumes.
