Precision Machining for Semiconductor, Aerospace, and Medical Components: Surface Roughness & Particle Control

 Precision Machining for Semiconductor, Aerospace, and Medical Components: Surface Roughness & Particle Control

In high-end manufacturing industries such as semiconductors, aerospace, and medical devices, surface roughness and particle control are critical factors for component acceptance. European and American customers typically require internal cavities and fluid channels to achieve a surface roughness of Ra ≤ 0.2–0.4 μm, while ensuring no particle shedding. This requirement goes beyond visual brightness and directly impacts the functionality and reliability of the components.

For example, in the semiconductor industry, residual micro-particles in cavities and fluid channels can enter vacuum or fluid circulation processes, potentially causing wafer defects and significant financial losses. Therefore, components must undergo ultra-precision polishing, rigorous cleaning, and microscopic inspection to ensure particle-free surfaces.

In contrast, some domestic workshops still rely on "shine is enough" polishing methods, overlooking quantitative surface roughness control and particle shedding risk assessment. This gap is a critical concern for international clients when auditing suppliers.

Mid Precision has extensive experience in this field. We can control surface roughness to meet strict client requirements during ultra-precision polishing, and apply professional cleaning and inspection processes to ensure components reach high cleanliness standards. This not only guarantees functional stability but also gives clients confidence in high-risk applications across semiconductor, aerospace, and medical industries.
