Abstract
PURPOSE: To reduce the circuit substrate forming process while eliminating the control of thickness and hardness of the nickel by bonding a nickel foil having a specified thickness and hardness on the insulated base material.
CONSTITUTION: A nickel foil with a thickness of 9 to 15 μ and a hardness exceeding 90 micro Vickers necessary for the LED pellet junction is directly bonded on an insulated based material made of phenol, paper epoxy, glass cloth epoxy or the like. With such an arrangement, it is possible to eliminate the complicated control of the thickness and the hardness in the case of nickel plating. With the formation of desired nickel pattern simply by photoetching, a substrated can be obtained in accordance with the specifications of finishing nickel. The substrate in accordance with the metal and silver finishing specifications can be obtained through direct metal or silver plating on the substrate with the nickel pattern formed. An aluminium foil may be used in place of the nickel foil.
