South Korea continues to lead the global smartphone camera supply chain, focusing on higher-resolution sensors and enhanced optical performance. However, as components become thinner and more sensitive, manufacturers face increasing challenges in contamination control during assembly. In particular, dust-catching adhesive dispensing for infrared filters in CCM camera modules requires extremely stable volume control and precise alignment to protect imaging quality.

To meet these growing requirements, a major South Korean camera module producer asked for an Inline Visual Dispensing Machine equipped with a piezoelectric jet valve and dual workstation configuration. This upgrade transformed their production capability, enabling two dispensing processes on a single system and significantly improving UPH.

Inline Dispensing Solution Optimized for Korean Production Demands

The advanced motion control system uses linear motors on X, Y axes with a grating ruler resolution of 0.5 microns delivering:

• Repetitive positioning accuracy within ±10 microns for X, Y, and Z axes
• Maximum motion speed of 1300 mm per second, enabling faster cycle time
• Smooth and stable dispensing even for micro-scale dot patterns

The machine supports a wide working envelope of 600 mm by 700 mm, ensuring compatibility with CCM, VCM, FPC, MiniLED and SMT production lines in Korea.

By integrating dual valves and dual tracks, the customer now performs dust-catching, glue dispensing and lens-related processes in parallel. One machine covers two workflows reducing capital cost and cleanroom floor usage.

 
Proven Results from a Korean Factory

Based on actual customer data the adoption delivered:

•  UPH improvement with dual station continuous operation
•  Better yield stability due to visual mark and appearance feature positioning
•  Non-contact jetting avoids part scratches and contamination
•  Precise glue volume preventing overflow and voids along the IR filter edges
•  Stable production even with dark colored optical components

Additionally, the track system supports automatic width adjustment of 40 to 205 mm and maintains parallelism below 0.1 mm, ensuring smooth inline handover with Korea‘s established transfer carriers.

Supporting High Growth in Korean Optical Module Manufacturing

Local manufacturers are now preparing for the next generation of smartphone optical upgrades, including periscope lenses AI vision enhancement, and anti-reflection coatings. The Inline Visual Dispensing Machine has already demonstrated how automated dust-catching gluing plays an essential role in protecting sensitivity and maintaining image clarity in high-resolution camera modules.

By enabling higher throughput and micro precision control with a compact investment footprint, Korean factories gain stronger competitiveness in the global smartphone device market paving the way for scalable smart production in advanced optical assembly.
