Consumer electronics camera module metered filling: polyurethane potting compound case study

Background

An equipment integrator / manufacturer in Consumer electronics needed to metered filling on a camera module using polyurethane potting compound.

Process challenge

Supply pressure ripple during continuous running, causing volume drift.

Solution

We recommended Screw Valve + Dispensing 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 0.05 mL with deviation within ±3%.
• Cycle time 0.6 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Consumer electronics
• Workpiece: camera module
• Fluid: polyurethane potting compound
• Process: metered filling
• Recommended lines: Screw Valve, Dispensing Valve
