Since its first laminate manufacturing plant in 1988 in Shenzhen, the Kingboard Laminates Group (KL) expanded its production of new CCL, including FR4 and CEM1. Vertically, KL expanded into the production of key upstream component materials, including copper foil, glass yarn, glass fabric and epoxy resin. These developments have placed KL in a competitive position by optimizing economies of scale and achieving cost efficiencies. KL currently operates more than 20 manufacturing plants in China.
