New energy and storage storage module underfill: thermal grease case study

Background

An equipment integrator / manufacturer in New energy and storage needed to underfill on a storage module using thermal grease.

Process challenge

Supply pressure ripple during continuous running, causing volume drift.

Solution

We recommended Glue Supply System + Screw Valve + Glue Distributing Machine, with using a servo dispensing module with a programmable speed profile to hold a constant extrusion rate.

Result

Potting void defects reduced from 4% to below 1%.
Shot volume 0.05 mL with deviation within ±2%.
Cycle time 0.5 s per dot with no stringing or dripping during continuous running.
