The invention relates to an FBGA arrangement, comprising a substrate on which
at least one chip is chip-bonded face-down, which has a central row of bonding
pads connected to contact islands (landing pads) on the substrate by a bonding
channel in the substrate via wire bridges, which substrate, for its part, is provided
with soldering balls—arranged in an array—for contact connection to
a printed circuit board, and the contact islands and the soldering balls being
connected to one another via a rewiring of the substrate. The preferred embodiment
of the invention is intended to provide an FBGA arrangement which supports the
center pad row technology and at the same time has low electrical parasitics. This
is achieved by virtue of the fact that at least two substrates (1, 2) are
provided, the substrates (1, 2) are provided substratewise in each case
with bonding channels (3, 4) having different dimensions, in a manner forming
a multistage bonding channel, the bonding channels (3) in the ball-side
substrate (2) having larger dimensions than those in the chip-side substrate (1).
