Automotive electronics ECU unit potting: two-component epoxy case study

Background

An equipment integrator / manufacturer in Automotive electronics needed to potting on a ECU unit using two-component epoxy.

Process challenge

Particle fillers settling and clogging after long idle periods.

Solution

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

Result

• Volume drift held within ±3% over an 8-hour run.
• Shot volume 0.05 mL with deviation within ±3%.
• Cycle time 0.3 s per dot with no stringing or dripping during continuous running.
