Solderless `fingerprint` RF shield

A method of constructing a substantially cylindrical coil coil having a circumference C comprising the steps of:

• a) creating a support having a length L greater than C;
• b) attaching a plurality of multi-loop `fingerprint` coils each having a center, on a first surface of the support at predetermined locations relative to each other and the circumference C such that centers of the coils are substantially perpendicular to predetermined first set of axes through said cylindrical coil assembly when the support is rolled;
• c) rolling the support and coils into a cylindrical shape to result in a coil assembly in which the centers of the coils are substantially perpendicular to the predetermined first set of axes;
• and
• d) attaching a plurality of multi-loop `fingerprint` coils each having a center, on a second surface of the support at predetermined locations relative to each other and the circumference C such that centers of the coils are substantially perpendicular to a predetermined second set of axes through said cylindrical coil assembly when the support is rolled.

A substantially cylindrical coil assembly having a circumference C comprising:

• a) a rolled support having a length L greater than circumference C, such that the support overlaps itself;
• b) an integral number of `fingerprint` coils each having a center, positioned on a first surface of the support such that, when rolled, the centers of the coils are substantially perpendicular to a predetermined first set of axes;
• and
• c) an integral number of `fingerprint` coils each having a center, positioned on a second surface of the support such that, when rolled, the centers of the coils are substantially perpendicular to a predetermined second set of axes.
