Optoelectronics and display lens holder coating: thermal grease case study

Background

An equipment integrator / manufacturer in Optoelectronics and display needed to coating on a lens holder using thermal grease.

Process challenge

Bead width and height must stay stable with no edge creep.

Solution

We recommended Dispensing Valve + Glue Distributing Machine, with tuning rotor/stator fit and flow path geometry to the filler particle size.

Result

• Volume drift held within ±3% over an 8-hour run.
• Shot volume 0.1 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
• Workpiece: lens holder
• Fluid: thermal grease
