Optoelectronics and display light guide assembly underfill: filled thermal gel case study

Background

An equipment integrator / manufacturer in Optoelectronics and display needed to underfill on a light guide assembly using filled thermal gel.

Process challenge

Large potting volume where voiding and incomplete fill are hard to balance.

Solution

We recommended Dispensing Valve + Glue Distributing Machine, with fitting quick-change interfaces and parameter recipes to shorten setup time.

Result

• Overflow and stringing defects reduced by roughly 60%.
• Shot volume 0.05 mL with deviation within ±2%.
• Cycle time 0.8 s per dot with no stringing or dripping during continuous running.
