Background
An equipment integrator / manufacturer in Optoelectronics and display needed to coating on a lens holder using conductive silver adhesive.
Process challenge
Bead width and height must stay stable with no edge creep.
Solution
We recommended Dispensing Valve + Glue Distributing Machine, with replacing time-pressure control with a positive-displacement screw valve to meter by volume.
Result
- Volume drift held within ±3% over an 8-hour run.
- Shot volume 0.008 mL with deviation within ±2%.
- Cycle time 1.1 s per dot with no stringing or dripping during continuous running.
Project facts
- Industry: Optoelectronics and display
