Semiconductor Manufacturing Adaptation Principle: Selecting Filters Based on Cleanliness Grades
A recent chip semiconductor workshop client we consulted with has adopted an MAU+DDC+FFU design for its cleanroom system, yet all cleanrooms of different grades are equipped with U15 filters and DC FFUs.
In this regard, the professional team at Baihong Purification recommends: filters with appropriate filtration precision should be matched according to the cleanliness grade of the workshop.
Workshops with high-precision requirements such as Class 100 and Class 1000 are relatively sensitive to tiny particles. Particle contamination may affect chip yield, making U15 filters a suitable choice for these scenarios.
For Class 10,000 and Class 100,000 workshops, the core requirement is to intercept 0.5-micron particles. Blindly using U15 filters may lead to a sharp increase in resistance due to excessive filtration precision, which in turn forces the air conditioning system to operate at full load and pushes up electricity costs to a certain extent.
Additionally, U15 filters have relatively high procurement costs, are prone to dust accumulation, and require frequent replacement. This may not only increase subsequent maintenance expenses but also disrupt production continuity due to downtime for filter replacement.
Baihong Purification: Your Professional Choice for DC FFUs in Semiconductor Workshops
As a manufacturer with over a decade of experience in the cleanroom equipment industry, Baihong Purification has an in-depth understanding of the environmental characteristics and application scenarios of semiconductor chip workshops, with a wealth of practical experience to its name.
Our DC FFU Clean Air Supply Units are specially designed for semiconductor manufacturing scenarios, boasting three core advantages:
1.Digital Group Control Capability: Enables centralized intelligent control and real-time monitoring of the operational status of each FFU.
2.Precise Parameter Control: Dynamically tracks the temperature rise and pressure difference of each unit, helping maintain equipment within an optimal operational range.
3.Full-Cycle Cost Optimization: While ensuring high production yield and equipment stability, it minimizes energy consumption costs through low-power operation, supporting long-term cost savings for our clients.
Baihong’s DC FFU Clean Air Supply Units helps precisely meet the needs of workshops with different cleanliness grades. Meanwhile, with the support of intelligent management and control, it achieves the dual value of “stable production + energy conservation and consumption reduction”.
