An electronic system comprising: an electronic system support substrate
for the attachment of components of the electronic system, the electronic
system support substrate including electric signal propagation paths for
the propagation of electric signals between the system components; at
least a first and a second electronic components wherein at least the
first electronic component is part of a module in mechanical and
electrical connection with the electronic system support substrate, the
module comprising a module substrate to which the first electronic
component is at least mechanically connected, and an electric coupling
between the first and the second electronic components, for the electric
coupling allowing the first and the second electronic components exchange
of electric signals. The electric coupling comprises a direct electric
connection particularly formed by a flexible electrical interconnection
member, between the first and the second electronic components, the
electric connection being independent of the electronic system support
substrate.
