FFU & PAO Testing Solutions for PCB Cleanrooms: KOWA x Unimicron Case Study
Enhancing Cleanroom Performance with FFUs and PAO Testing
KOWA is proud to spotlight a recent success story involving Unimicron, a world-leading PCB and IC carrier manufacturer trusted by major global brands such as Intel and Apple. In this unique collaboration, KOWA went beyond equipment supply—we delivered a full-service solution that included FFU installation and PAO testing for the expansion of Unimicron’s Yangmei facility.
Project Overview: FFU Integration for Class 100 PCB Cleanroom
Unimicron’s Yangmei expansion project required the construction and validation of Class 100 cleanroom environments. Due to the high precision required for PCB production, the challenge was to maintain cleanliness while optimizing cost and efficiency.
Project Objectives:
Build a Class 100 cleanroom for PCB manufacturing
Install energy-efficient FFUs with minimal disruption
Conduct reliable PAO testing for HEPA filter integrity
Client-Specific Challenges and Customized Solutions
