    摘要: The invention provides multilayer circuit boards and methods for formation of a sequential build circuit board. Among other things, glass fiber reinforced copper clad epoxy substrates, required to provide strength or rigidity to prior boards, are not required for preferred circuit boards of the invention. Preferred methods of the invention include applying a dielectric coating onto a support; forming recesses in the dielectric coating that define openings including opening for at least one reinforcing member; depositing copper metal into the recesses to form a first layer; applying a second dielectric coating onto the first circuit layer; forming recesses in the second dielectric coating that define openings including openings for at least one reinforcing member in registration with the one or more reinforcing members in the first layer; depositing metal into the recesses in the dielectric coating to form the second layer; and repeating the process to form sequential build board having the desired number of layers.
