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.
