Abstract:
The disclosure relates to an X-ray opaque coating containing an epoxy resin including an iodinated phenol covalently bonded to a glycidyl ether. Iodinated phenol covalently bonded to a glycidyl ether may include iodinated bisphenol A, such as tetraiodobisphenol A, a glycidyl ether of mono-iodophenol, bis-iodophenol, tri-iodophenol, or combinations thereof. The coating may include an X-ray opaque inorganic filler. The disclosure also relates to an electronic component including a substrate and at least one device coupled to the substrate with an obfuscation layer disposed over the substrate for obscuring the device from an X-ray source. The obfuscation layer may include an X-ray opaque coating. The disclosure additionally relates to a method of obscuring at least a portion of an electronic component by depositing an obfuscation layer that may include an X-ray opaque coating and a method of forming an X-ray opaque coating.
