SOME SORT OF wire-to-board connector, as the particular name suggests, connects a wire/cable with a PCB. The wire connections are like the one used for wire-to-wire connection, and the board cable connections are, for the most part, press-in or soldered two-piece connectors; although, some card edge versions remain being used. The mating interface for your separable connection may be identical to that of a wire-to-wire connector in the same product family. While there are various applications of wire-to-board connectors, this trend is toward cable-to-board connectors, and also cable assemblies, to make benefits of IDC. Board-to-board (BTB) connectors utilized to connect printed world boards (PCB), electronic components that incorporate a conductive pattern printed on the surface of the insulating base in an exact and repeatable manner. Each terminal using a BTB connector is attached to a PCB. A BTB connector includes housing as well as a specific number of terminals. The terminal manufactured from a conductive content (mostly copper alloy), and plated to further improve conductivity and antirust. Terminals transmit the current/signal between PCBs linked by BTB; the housing consists of insulating material (mostly plastic). https://www.hrb-connector.com/Wire-to-Board-Connector-pl3238786.html
