NPV (Negative Pressure Vacuum)  Hole-plugging Printing

NPV technology is currently the industry's unique plug hole printing patented technology, especially for small apertures below 0.2mm has a significant effect. Taking the 1.7mm thick substrate in the upper left picture as an example, it can achieve a rapid single-point plugging of a 0.2mm aperture and greatly eliminate the problem of air bubbles in the hole.

(The highest plug hole aspect ratio is up to 60)
