Automotive electronics ECU unit potting: filled thermal gel case study

Background

An equipment integrator / manufacturer in Automotive electronics needed to potting on a ECU unit using filled thermal gel.

Process challenge

Particle fillers settling and clogging after long idle periods.

Solution

We recommended Pneumatic Valve + Glue Supply System, with replacing time-pressure control with a positive-displacement screw valve to meter by volume.

Result

Volume drift held within ±3% over an 8-hour run.
Shot volume 0.4 mL with deviation within ±3%.
Cycle time 0.3 s per dot with no stringing or dripping during continuous running.
