Medical and consumables medical catheter underfill: thermal grease case study

Background

An equipment integrator / manufacturer in Medical and consumables needed to underfill on a medical catheter using thermal grease.

Process challenge

Particle fillers settling and clogging after long idle periods.

Solution

We recommended Screw Valve + Sensor, with adding regulated supply with a drum pump for continuous feed to suppress pressure ripple.

Result

• Potting void defects reduced from 4% to below 1%.
• Shot volume 0.4 mL with deviation within ±2%.
• Cycle time 0.7 s per dot with no stringing or dripping during continuous running.
