Consumer electronics acoustic component underfill: thermal grease case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to underfill on a acoustic component using thermal grease.

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

• Overflow and stringing defects reduced by roughly 60%.
• Shot volume 0.4 mL with deviation within ±3%.
• Cycle time 0.3 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Consumer electronics
• Workpiece: acoustic component
• Fluid: thermal grease
• Process: underfill
• Recommended lines: Screw Valve, Dispensing Valve
