Laminate materials with embedded heat-generating multi-compartment microcapsules

A composite material incorporates multi-compartment microcapsules that produce heat when subject to a stimulus such as a compressive force or a magnetic field. The stimulus ruptures an isolating structure within the multi-compartment microcapsule, allowing reactants within the multi-compartment microcapsule to produce heat from an exothermic reaction. In some embodiments, the composite material is a laminate used in the manufacture of multi-layer printed circuit boards (PCBs) and provides heat during the curing process of the multi-layer PCBs to ensure a consistent thermal gradient in the multi-layer product.
