Abstract: A method for manufacturing a circuit board with a buried element having high density pin count, wherein a micro copper window formed in a first circuit by patterned dry film electroplating is easily controlled less than 50 μm so that the micro conduction holes formed after the laser drilling each has a diameter greatly shrunk less than 50 μm so as to highly increase density of the micro conduction holes, thereby facilitating in burial of the buried element with the high density pin count. Additionally, by disposing the micro conduction holes in the same elevation, optically aligning a fixing position for the buried element can be controlled precisely.

Abstract: A method for manufacturing microthrough-hole includes electroplating a metal layer on a carrier plate, patterning the metal layer to form a first circuit having copper pads, covering the first circuit with a photoresist layer and not covering the copper window between two of the copper pads, etching the metal layer beneath the copper window and removing the photoresist layer, sequentially forming an insulation layer and a second circuit on the first circuit and the copper window, the second circuit layer having a stop pad corresponding to the copper window, removing the carrier plate, upward drilling through the insulation layer between the stop pad and the copper window to form a microthrough-hole beneath the stop pad, and forming a conductive layer in the microthrough-hole to form the microthrough-hole connecting the first and second circuits. The microthrough-hole and its occupied area is greatly reduced, thereby achieving high circuit density.
