Vietnam has rapidly become a global center for notebook and mobile electronics manufacturing. As device designs continue to shrink, manufacturers rely on flexible printed circuits (FPCs) to support thinner structures and denser signal transmission. These FPC components require chip coating encapsulation and protective filling to ensure durability and long-term reliability, especially in high flex areas. However, the traditional dispensing process in FPC assembly often causes inconsistent glue volume, slow cycle time, and frequent rework when using low-temperature curable adhesives. To solve these challenges, a leading electronics manufacturer in Vietnam implemented the FS600DDF Dual Valve Inline Dispensing Equipment with piezoelectric jet valve technology.  Inline Dual Valve Dispensing for Higher Production Speed The FS600DDF is engineered to meet high-throughput production lines. A dual valve configuration allows two dispensing points in parallel, significantly improving UPH. The motion system supports fast acceleration and stable accuracy even on ultra-thin notebook FPC substrates. With piezoelectric jetting, the system can dispense contact-free free ensuring: Material consistency for chip coating and protective filling Controlled fluid behavior for low-temperature curing adhesives Clean edge finish without overflow or splashing Better protection of sensitive FPC circuits This upgrade allowed the factory to confidently reach 100000 units per day 24h operation, fulfilling the customer’s high-volume manufacturing plan.  Production Results Verified in Vietnam After introducing the FS600DDF system the factory reported:  Productivity increased to 10w pcs per 24h with stable takt time  Precise glue volume control reduced repair and inspection workload  Excellent compatibility with low-temperature thermal-curing epoxy  Lower adhesive waste and better coating reliability  Inline automation reduced labor dependency and improved traceability These results demonstrate how automated dispensing can help Vietnam manufacturers strengthen quality while reducing operational cost in FPC assembly. Enabling the Next Stage of Vietnam Electronics Manufacturing With international notebook brands continuing to expand their supply network in Vietnam factories are upgrading from manual to smart automation solutions to remain competitive. The FS600DDF Dual Valve Inline Dispensing Equipment supports that transition with high speed and high stability micro dispensing performance. By helping local manufacturers meet advanced packaging and reliability standards the FS600DDF plays a key role in accelerating Vietnam’s transformation into a high performance electronics production powerhouse in Southeast Asia.

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.

Vietnam’s consumer electronics industry has been expanding rapidly, driven by strong exports and growing local production capacity. However, many factories are still facing challenges in precision assembly — especially when bonding micro-components such as inductor modules, speaker diaphragms, and small protective housings. When the dispensing volume is too large, adhesive overflow can lead to assembly defects and costly rework. Too small, and bonding reliability cannot be guaranteed for high-vibration applications like portable audio devices and mobile phones. This has pushed more manufacturers in Vietnam to shift from manual assembly toward fully automated mounting and dispensing solutions.  Transition to Automation: A Real-World Case from Vietnam A leading electronics manufacturer in Bac Ninh Province recently adopted a Fully Automatic Mounting & Dispensing Machine to optimize the assembly process for inductor speaker components. Traditionally, operators manually applied epoxy glue and attached the diaphragm to the housing. This caused issues including: Irregular glue volume Visible glue overflow and scattered droplets High rejection rates Inconsistent output depending on operator skill To solve these problems, the customer integrated the machine with a high-precision piezoelectric jet valve, allowing for non-contact micro-dispensing with precise volume control — ideal for high-density product layouts.   Proven Results: High Efficiency & Stable Quality After switching to automated dispensing and mounting, the factory achieved:  Fast cycle time handling 8–12 glue points per part  Repeatable spot diameter as small as 0.27 mm  Accurate bonding with no diaphragm displacement  Significantly reduced overflow & scattered adhesive  Higher yield with consistent product quality  Labor cost savings & improved overall output The system supports epoxy adhesives widely used in Vietnam’s electronics industry, ensuring strong bonding, environmental resistance, and long-term stability in acoustic performance. Additionally, automated alignment and visual inspection ensure every diaphragm is correctly positioned before glue curing — something difficult to guarantee in manual operations. Enabling the Next Stage of Vietnam’s Electronics Manufacturing This case demonstrates that automation + piezoelectric jetting is not only technically feasible, but also commercially advantageous for Vietnam’s rapidly growing component industry. By adopting advanced dispensing automation, Vietnamese manufacturers are taking an important step toward smart production and sustainable expansion — ensuring they can continue to serve the world’s top electronics brands with speed, quality, and consistency.
