The Global Bonding Sheets Market often referred to as prepreg bonding sheets or specifically designed bonding films, are advanced composite materials primarily used in the manufacturing of multi-layer printed circuit boards (PCBs) and other high-performance electronic components.
These sheets consist of a resin system (e.g., epoxy, polyimide, cyanate ester) impregnated into a reinforcing material (e.g., fiberglass, aramid) and partially cured (B-staged). During the PCB lamination process, these sheets are placed between core layers and subjected to heat and pressure, causing the resin to flow, bond, and fully cure, creating a robust, insulating, and mechanically stable connection between the layers. Their critical role lies in ensuring signal integrity, thermal management, and structural reliability in complex electronic assemblies.
