INDIAN HISTORY

Detailed explanation-1: -Copper clad boards are commonly used in the electronic industry. Copper is a conductive material that enables heat dissipation in PCB. An increasing number of electronic devices are featuring copper clad PCBs. There is no doubt these boards play a significant role in electronics production.

Detailed explanation-2: -Copper Hoard culture describes find-complexes which mainly occur in the western Ganges–Yamuna doab in the northern part of the Indian subcontinent. They occur in hoards large and small, and are dated to the first half of the 2nd millennium BCE, although very few derive from controlled and dateable excavation contexts.

Detailed explanation-3: -In the region of Ganga-Yamuna doab, almost all the Copper Hoards have been found along with deposits of the OCP, which reflects that the Copper Hoards are associated with OCP people in doab. But their cultural association in Bihar, Bengal, and Orissa is not clear.
