Automotive electronics harness connector underfill: filled thermal gel case study

Background

An equipment integrator / manufacturer in Automotive electronics needed to underfill on a harness connector using filled thermal gel.

Process challenge

Large potting volume where voiding and incomplete fill are hard to balance.

Solution

We recommended Pneumatic Valve + Glue Supply System, with fitting quick-change interfaces and parameter recipes to shorten setup time.

Result

• Overflow and stringing defects reduced by roughly 60%.
• Shot volume 0.008 mL with deviation within ±3%.
• Cycle time 0.6 s per dot with no stringing or dripping during continuous running.

Project facts

• Industry: Automotive electronics
• Workpiece: harness connector
• Fluid: filled thermal gel
• Process: underfill
• Recommended lines: Pneumatic Valve, Glue Supply System
