Background
An equipment integrator / manufacturer in Automotive electronics needed to underfill on a harness connector using conductive silver adhesive.
Process challenge
Large potting volume where voiding and incomplete fill are hard to balance.
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
- Overflow and stringing defects reduced by roughly 60%.
- Shot volume 0.4 mL with deviation within ±3%.
- Cycle time 0.6 s per dot with no stringing or dripping during continuous running.
