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.
Project facts
- Industry: Semiconductor and packaging
- Workpiece: power device
- Fluid: polyurethane potting compound
- Process: metered filling
- Recommended lines: Servo Dispensing Module, Screw Valve
