Consumer electronics TWS earbud housing dispensing: conductive silver adhesive case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to dispensing on a TWS earbud housing using conductive silver adhesive.

Process challenge

Tight cycle time with frequent changeovers that squeeze setup time.

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 0.1 mL with deviation within ±3%.
Cycle time 0.3 s per dot with no stringing or dripping during continuous running.
