Nationwide Exclusive! RANA's 9,000 ㎡ Class 10k Clean Workshop

Introduction In the fluorine material lining industry, a Class 10k dust-free clean workshop represents a highly sought-after hardware benchmark that most enterprises cannot attain. RANA (Jiangsu Ruineng Fluorine Material Technology) is the only domestic enterprise that not only possesses such a facility but also operates a total 9,000 ㎡ clean production complex, setting an industry-leading standard.

Understanding Class 10k Clean Workshops

Per ISO 14644-1 international standards, clean workshops are classified by particle concentration: ISO Class 4 (Class 10) for semiconductor lithography, ISO Class 5 (Class 100) for wafer manufacturing, ISO Class 6 (Class 10k, ≤35,200 particles ≥0.5μm per m³) for high-purity fluorine lining production, ISO Class 7 (Class 100k) for semiconductor packaging, and ISO Class 8 (Class 1M) for general electronics assembly.
For fluorine lining products used in IC semiconductor and wet electronic chemical applications, strict purity requirements mandate metal impurity levels ≤0.1ppb (SEMI C12 grade) and particle contamination ≤0.2 particles/μL. A Class 10k environment is essential to prevent airborne particles from adhering to PTFE/PFA surfaces and compromising product purity.

RANA's 9,000 ㎡ Facility: Nationwide Exclusive

RANA's clean complex comprises 1,800 ㎡ of Class 10k space for PPB-PPT grade high-purity lining production, and 7,200 ㎡ of Class 100k space for PPM-PPB grade medium-high purity products.
This facility is unique in China: most domestic lining manufacturers have no clean workshops at all and are limited to low-end products; the few with Class 1k/10k facilities only have areas of a few hundred square meters, limiting their production capacity for high-end products. RANA is the only enterprise capable of simultaneously delivering high-purity products and large-scale production capacity.
This advantage translates to strong market competitiveness: we can fulfill high-end orders for 12-inch wafer fabs requiring PPB-grade purity, ensure reliable delivery thanks to our large production capacity, and offer competitive pricing through economies of scale.

Fully Imported Key Equipment for Precision Production

Complementing our clean workshop infrastructure, RANA has invested in imported key production equipment: automatic welding robots for high-integrity PTFE welds, precision injection molding machines for high-accuracy PFA components, CNC cutting machines for minimal material waste, and advanced testing equipment including spark testers and insulation resistance testers. These imports offer higher precision, better long-term stability, and longer service life compared to domestic alternatives, ensuring consistent production quality and continuity.
