A pair of releasing layer is adhered at each bonding layer. The releasing layer comprises one of the conductive metal or the insulating material.
Abstract:
A carrier member for transferring circuits, a coreless printed circuit board using the same, and methods for manufacturing the same minimize damage to circuits and improve reliability of the printed circuit board by forming a concavo-convex only in the bottom of an inner side of a circuit pattern. A carrier plate composed of a carrier layer(302a, 302b) and a barrier layer(303a, 303b) on both sides of thermal adhesive representing non-adhesive property in a thermal process is attached to both sides carrier structure. The barrier layer is the metal seed layer except copper. A plating resist is coated on the part including lands or the part except for the circuit formation part which does not include the lands, on the barrier layer of the both sides carrier structure. The circuit pattern is formed by electro copper plating the opened circuit formation part through the plating resist. The concavo-convex part is formed by roughing an exposed surface of the circuit pattern. A pair of carrier members for transferring circuits is obtained and separated from the thermal adhesive by removing the plating resist and thermal treating both sides carrier structure.

A bottom substrate of a POP(Package On Package) and a method of manufacturing the same are provided to increase the number of integrated circuits mounted thereon without increasing a size of a solder ball. A bottom substrate of a POP is electrically connected to a top substrate by using a solder ball. The bottom substrate includes a core substrate(10), a solder ball pad(12) formed on a surface of the core substrate corresponding to a position of the solder ball, an insulating layer(20) stacked on the core substrate, a through-hole formed by removing a solder ball pad part from the insulating layer to expose the solder ball pad, and a metal layer(28) for filling up the through-hole. The metal layer is electrically connected to the solder ball. The insulating layer is formed by stacking photoresist on the core substrate and hardening the photoresist.
