built-in Copper Coin PCB-- HONTEC uses prefabricated copper blocks to splice with FR4, then uses resin to fill and fix them, and then combines them perfectly by copper plating to connect them with the circuit copper
The so-called Buried Copper Coin PCB is a PCB board in which a copper Coin is partially embedded on the PCB. The heating elements are directly attached to the surface of the copper Coin board, and the heat is transferred out through the copper Coin.
