Consumer electronics acoustic component metered filling: filled thermal gel case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to metered filling on a acoustic component using filled thermal gel.

Process challenge

Micro-litre volumes with expensive material and no waste allowed.

Solution

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

Result

• Overall equipment availability improved by about 12%.
• Shot volume 1.5 mL with deviation within ±3%.
• Cycle time 0.6 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Consumer electronics
• Workpiece: acoustic component
• Fluid: filled thermal gel
• Process: metered filling
• Recommended lines: Screw Valve, Dispensing Valve
