Optoelectronics and display LED module coating: polyurethane potting compound case study

Background

An equipment integrator / manufacturer in Optoelectronics and display needed to coating on a LED module using polyurethane potting compound.

Process challenge

High fluid viscosity and resistance causing pneumatic extrusion to lose speed.

Solution

We recommended Dispensing Valve + Glue Distributing Machine, with using a high-flow pneumatic valve for staged potting together with vacuum de-airing.

Result

Material utilisation improved by about 8% with visibly less waste.
Shot volume 0.02 mL with deviation within ±2%.
Cycle time 1.1 s per dot with no stringing or dripping during continuous running.
