company news about What are the requirements for the modular cleanroom level in the auxiliary area of the electronics factory？

These modular cleanrooms feature adjustable air change rates and localized purification systems.

During peak operational hours, air exchange rates can increase to 20-30 times per hour to counteract elevated particle emissions from material handling.

In idle periods, rates reduce to 10-15 times per hour to save energy. Localized laminar flow hoods or portable HEPA filters are deployed at critical workstations to create micro-environments with higher cleanliness than the surrounding area.

Unlike core production zones that demand ISO 1-5 (Class 1-100) standards, auxiliary areas such as material preparation rooms, tool maintenance stations, and staff buffer zones typically adopt ISO 6-8 (Class 1000-100,000) cleanliness levels.

This tiered design aligns with the actual contamination sensitivity of tasks—for example, component packaging preparation only requires ISO 7 standards to prevent particulate adhesion without overinvesting in ultra-high purification.
