The superiority of the Ebina proposal process! Achieving ultra-high density fine holes without cracks or chipping.
Our processing technology enables the creation of glass without cracks or chips, and allows for ultra-high-density fine holes. The roughness of the sidewalls of the through holes is Ra0.08μm. We can achieve smooth sidewalls, enabling miniaturization and integration of devices. The shapes of the through holes can be selected from straight, hourglass, or tapered. 【Features】 ■ No cracks or chips ■ Smooth sidewalls ■ Ultra-high-density fine holes ■ Miniaturization and integration of devices *For more details, please refer to the PDF document or feel free to contact us.
