Semiconductor and packaging power device metered filling: polyurethane potting compound case study

Background

An equipment integrator / manufacturer in Semiconductor and packaging needed to metered filling on a power device using polyurethane potting compound.

Process challenge

Supply pressure ripple during continuous running, causing volume drift.

Solution

We recommended Servo Dispensing Module + Screw Valve, with pairing a micro screw valve with a level sensor in closed loop for accurate volumetric output.

Result

Setup time cut from 40 minutes to under 15 minutes.
Shot volume 0.1 mL with deviation within ±2%.
Cycle time 0.7 s per dot with no stringing or dripping during continuous running.
