A semiconductor chip assembly includes a semiconductor chip that includes
a conductive pad, a conductive trace that includes a routing line, a
metal pillar and an enlarged plated contact terminal, a connection joint
that electrically connects the routing line and the pad, and an
encapsulant. The chip and the metal pillar are embedded in the
encapsulant, the routing line extends laterally beyond the metal pillar
towards the chip, the metal pillar is welded to the routing line and
includes a ball bond and a stem, and the plated contact terminal is
plated on the stem.
