Polyurethane spray coating of aluminum wire bonds to prevent corrosion and suppress resonant oscillations

, 2015
Unencapsulated aluminum wedge wire bonds are common in particle physics pixel and strip detectors. Industry-favored bulk encapsulation is eschewed due to the range of operating temperatures and radiation.
