Below is a list of PCB Connectors manufacturers from Bohemia, New York. PCB (printed circuit board) connectors refer to a type of electronic connector that is used to transmit electrical signals between either two printed circuit boards or a printed circuit board and another type of electric circuit. A printed circuit board is a device used to mechanically support as well as electronically connect various electrical components by means of conductive pathways that are etched into copper sheets and then laminated onto a non-conductive material known as a substrate.
