Do you know how to calculate the whole thickness of the metal dome array? As this is also very important for the whole product design.
Now we make the metal dome array the structure is double layers: Mylar + spacer + snap dome. The total thickness is equivalent to Mylar + snap dome thickness,here we can ignore the spacer thickness, because spacer is shrapnel to snap domes. Mylar thickness is generally 0.025mm, metal snap dome thickness according to the shape and diameter. Such as our 5mm, 160g,circle snap dome: the thickness is about 0.20mm, then the total thickness is 0.025 +0.20 = 0.225mm.
Now I think you should know to calculate the thickness? As each snap dome with different thickness, please contact us to request the drawing which with details information.
