Overview

  • Developed a facility which uses a pneumatic press and heated tip to attach microchips to PCB boards.

  • The system also includes:

  • Camera alignment system.

  • Precision XY adjustment to position the chip.

  • Bespoke vacuum chuck.

  • Computer software to aid with chip alignment.

Method

  • Iterative prototyping process using 3D printing.

  • Weekly presentations to senior engineers with cost-benefit analyses.

  • Custom parts CNC machined using precise tolerances.

  • Frequent correspondence with manufacturers.

  • Use of mills, lathes, drills etc.

  • Developed GUI using Python.

    Result

    • Completed at 30% under the €10,000 budget.

    • Bond strength increased 400% on average from un-pressurised sintering.

    • Achieved chip positioning with micron accuracy.
