FIRE-RESISTANT PRINTED CIRCUIT BOARD ASSEMBLIES

摘要

Printed circuit boards, or PCBs, may include cross-linked oligomers that have been modified to prevent corrosion and have reduced flammability. The oligomers may be functionalized to include cross-linkable moieties and a flame retardant. The modified materials are more environmentally benign and less toxic than current fiberglass technologies used to manufacture PCBs.

主权项

1. A printed circuit board assembly comprising:
at least one substrate sheet comprising a flame resistant material, the flame resistant material comprising functionalized oligosaccharides, the functionalized oligosaccharides comprising cross-linked oligosaccharides functionalized with a flame retardant; electrical conduction traces disposed on the substrate sheet; and electronic components disposed on the substrate sheet in contact with the electrical conduction traces.
