Why Semiconductor Equipment Bases Demand Zero Tolerance for Vibration
If you’re in the semiconductor, PCB drilling, or femtosecond laser industry, you already know the enemy: vibration. A tiny vibration in a CMM (Coordinate Measuring Machine) or an AOI (Automated Optical Inspection) system doesn’t just cause a bad reading; it causes batch failures. Standard m...Read more -
Beyond the Machine: Inside ZHHIMG’s 10,000㎡ Vibration-Free Workshop
You can’t manufacture what you can’t measure. This is a core belief at ZHHIMG®. But even the best measurement tools will fail if the environment is fighting against you. That’s why we invested heavily in a 10,000㎡ constant temperature and humidity workshop. But we didn’t just build a stand...Read more -
