Hot Bar Bonding

Hot bar bonding is the generic term used to describe a number of processes including Hot Bar Reflow Soldering, Heat Staking, ACF Laminating, Heat Seal Bonding and ACF Bonding.

Hot Bar Bonding is achieved using a thermode or “Hot Bar” which is heated and cooled under pressure using either a pulsed heat or constant heat reflow soldering power supply, creating an electrical connection between the materials joined.

Hot bar bonding is commonly used to connect flex-foils to printed circuit boards, small wires, small coax cables and very light or small components.
