A method of managing thermal warpage of a laminate which includes: assembling a stiffener and an adhesive on the laminate, the stiffener being a material that has a higher modulus of elasticity than the laminate; applying a force to deform the laminate a predetermined amount; heating the laminate, stiffener and adhesive to a predetermined temperature at which the adhesive cures to bond the stiffener to the laminate; cooling the laminate, stiffener and adhesive to a temperature below the predetermined temperature, the laminate maintaining its deformed shape.
