Elevating Customer Success with the IntelliJet Jetting System

Jump To Blog Content

Miniaturization poses complex fluid dispensing challenges for semiconductor manufacturers. While chip populations on substrates continue to increase, the gaps between them are becoming increasingly narrow – down to a few hundred microns today and moving towards < 100 µm in the near future. At the same time, bump heights underneath chips are decreasing to tens of microns for small form factors. These narrow spaces and tight geometries require a specialized solution to ensure efficient, high-quality dispensing results.

One customer in the semiconductor manufacturing industry shared how the IntelliJet^® Jetting System helped them overcome these obstacles – enabling them to improve quality and increase UPH by jetting consistent, narrow stream widths at high frequencies.

The Challenge

The application required large amounts of underfill to be dispensed into small gaps. Dispensing into small gaps requires minimal fluid volumes to achieve narrow, in-air stream widths. One approach to achieving narrow stream widths is decreasing the dot volume. However, that can result in a higher overall dot count and reduced productivity. Another method is increasing the dot volume, which improves productivity but increases the stream width and sacrifices quality. With these tradeoffs in mind, the challenge was finding a solution to balance the stream width and the flow rate without compromising quality and productivity goals.

The Solution

The Nordson applications team suggested the piezo-driven IntelliJet to support productivity, quality, and cost-of-ownership requirements.

The Results

The IntelliJet delivered significant benefits:

The higher jetting frequency increased UPH four times over the previous rate while maintaining quality.
ReadiSet^® Jet Cartridge and IntelliJet process adjustments delivered twice the dot volume while dispensing fewer dots and meeting total dispense volume requirements.
With a longer life cycle and patented internal self-calibration capabilities, IntelliJet reduced the cost of ownership by 40%.

By switching to the IntelliJet Jetting System, our customer achieved immediate results that created significant overall quality advancements and improved UPH, up-time, and cost of ownership in their manufacturing process.
