  • Sometimes one piece of NanoFoil® just isn’t enough…

    We often NanoBond® sputtering targets which are large enough to require multiple sheets of NanoFoil® to cover the width or length of a bond. You may even need to use two pieces of NanoFoil® that were sized for a different application, or if someone made a mistake cutting foil. Oops!

    Luckily, butting two pieces of NanoFoil® up to each other is quite easy, and although visible with ultrasonic testing the small gap should not cause much of a difference structurally or performance-wise. To secure the pieces during preparation, you can use high-temperature tape (as long as it is not in the bond interface). The heat from the first piece will active the second if they are in close proximity. This chain reaction is useful for both prototyping with incorrect sized pieces or mass production with pieces that are not large enough.
