Background:
As Intel® manufactures computer chips, they undergo different tests and quality control procedures. One particular procedure requires the application of diol (a liquid chemical compound) for the purpose of cooling the chip. This fluid must be removed completely and discarded prior to the final packaging of the product for the customer. Failure to remove the fluid completely would result in residual contaminants that would both affect the performance and appearance of the final product. The objective of this project is to design, build, and demonstrate a de-applicator for Intel® that quickly and completely removes thermal fluid from the surface of a microchip’s silicon die.

Results:
- Fluid removal was mathematically modeled.
- Designed, build, and coded a custom differential pressure monitoring device to measure mass flow rate information in 10 millisecond increments.
- De-applicator designed, built and tested.
- Discrepancies between mathematical model and physical tests are attributed to the compounding affect of several assumptions used to simplify the model.
- The device removed approximately 80% of the fluid within 900 milliseconds.
