FPC board dispensing: desktop dispensing machine use a Pneumatic jet dispensing valve to encapsulate

 Desktop vision dispensing machines paired with pneumatic jet valves are a mature and feasible solution for encapsulating mobile phone button pins, widely used in the industry. This combination is particularly suitable for the precision encapsulation of button pins on FPC flexible circuit boards, effectively preventing solder joint oxidation and providing reinforcement.


Below are the key technical points of this application solution:

I. Why choose a jet valve?

Compared to traditional needle dispensing, pneumatic jet valves offer several core advantages in FPC button encapsulation applications:



4 Axis Double Y SEC-E580SV-Y CCD Visua Desktop Despensing Machine

Second Intelligent’s SEC-E580SV-Y CCD Visua Desktop Despensing Machine Equipped with high-precision servo motors and precision ground ball screws, the visual dispensing platform offers more advanced and powerful functions. It can be integrated with vision positioning, automatic correction, dispensing inspection, laser height measurement and compensation, product information scanning, MES system connectivity, and other functions to meet the requirements of various industries and application scenarios.


III. Other Application Scenarios

Besides button pin encapsulation, this solution is also applicable to other stages of mobile phone production, such as waterproof adhesive dispensing for side buttons, bottom filling and reinforcement, and FPC component reinforcement.

IV. Key Points for Process Debugging

1. Injection Valve Parameter Settings
When using a Pneumatic injection glue dispensing valve to dispense UV adhesive, the following parameters need to be optimized to avoid air bubbles:
