Consumer electronics acoustic component potting: thermal grease case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to potting 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 using a precision dispensing valve with suck-back and servo three-axis motion for uniform coating.

Result

Filler-related stoppages reduced from three per week to one per month.
Shot volume 0.4 mL with deviation within ±3%.
Cycle time 0.9 s per dot with no stringing or dripping during continuous running.
