Background
An equipment integrator / manufacturer in Semiconductor and packaging needed to metered filling on a sensor die using two-component epoxy.
Process challenge
Micro-litre volumes with expensive material and no waste allowed.
Solution
We recommended Servo Dispensing Module + Screw Valve, with using a precision dispensing valve with suck-back and servo three-axis motion for uniform coating.
Result
- Overall equipment availability improved by about 12%.
- Shot volume 0.4 mL with deviation within ±2%.
- Cycle time 0.7 s per dot with no stringing or dripping during continuous running.
Project facts
- Industry: Semiconductor and packaging
- Workpiece: sensor die
- Fluid: two-component epoxy
