    Our solution
    Our solution
    1. Formulated bespoke silicone adhesive with supply partner (to bond to silicone rubber)
    2. Combined the formulated silicone with a low surface energy acrylic (for bonding to the plastic) to create a hybrid tape
    3. Developed a presentation with location features that allowed fast, repeatable and accurate assembly
    4. Designed an assembly method using a vacuum jig
