In Korea’s fast-growing smartphone and automotive camera industries, manufacturers often face a common but serious challenge: uneven transparent glue in camera modules. When adhesives for lens bonding, IR filter sealing, or VCM fixing are not applied with precision, defects such as bubbles, overflow, or misalignment appear. These issues reduce image quality, affect waterproofing, and increase rework rates. For factories under pressure to deliver consistent, high-volume output, even small dispensing errors quickly become costly.

The Need for Precise Dispensing in CCM Production

Camera modules are getting smaller, yet demand higher performance. Transparent glue, usually UV or epoxy adhesive, plays a key role in bonding and sealing. Traditional dispensing methods—such as needle-based contact dispensing—often struggle to deliver consistent micro-dots of glue. Problems like stringing, glue breakage, and overflow are especially common in Korea’s dense production lines, where speed and repeatability are essential.

What manufacturers need is a non-contact, high-speed, and bubble-free dispensing method that ensures every droplet of adhesive is uniform and placed exactly where it should be.

The Piezo Jet Valve: A Solution for Korean Camera Module Lines

The KPS2000 High-Precision Piezo Jet Valve addresses these challenges directly. Unlike conventional valves, it uses piezoelectric actuation to jet ultra-small, consistent droplets without touching the delicate surface of the camera module. This ensures:

• Precise glue control – No bubbles, no drawing, no overflow.
• High consistency – Each droplet has the same volume, improving yield.
• Non-contact dispensing – Protects sensitive lenses and IR filters from contamination.
• Material flexibility – Works with UV adhesives, epoxy, and black glue for shading.

With fast response and easy integration into automated lines, the KPS2000 makes it possible for Korean CCM manufacturers to improve both quality and efficiency.

Real Case: Lens Bonding and IR Filter Sealing

One Korean camera module supplier recently upgraded its lens bonding process. Previously, contact dispensing caused glue overflow around the lens edge, leading to high rejection rates. After switching to the piezo jet valve, the factory achieved stable micro-droplet control. The glue was placed exactly within the bonding line, preventing contamination of the lens surface.

In another case, a smartphone supplier used the valve for IR filter sealing. Here, consistency was critical—any missed spot could lead to light leakage. The piezo jet valve provided reliable coverage with no gaps, ensuring both performance and durability.

Conclusion: Improving Yield in Korean Optical Module Production

For Korean manufacturers competing in smartphones, vehicles, and imaging devices, uneven transparent glue is no longer acceptable. The KPS2000 piezo jet valve offers a proven solution—high precision, stable output, and compatibility with different adhesives. By adopting advanced jet dispensing, factories can reduce waste, improve reliability, and meet the strict demands of global customers.

If your camera module production still struggles with uneven glue, it’s time to consider upgrading your dispensing process.
