An automotive electronic device includes a pocket, which houses electronic components, bond wires connecting the electronic components, and a protective gel to encapsulate the electronic components and bond wires. A pocket cover has fins that protrude into the gel to reduce vibration of the gel and reduce vibration fatigue failure of the bond wires. The fins may: divide the gel into a plurality of cells; reduce the width of cells perpendicular to the bond wires; protrude deeper into the gel than the bond wires; and/or have differing shapes and/or depths.

Automotive electronic device having a cover with fins to reduce gel vibration

A piezoresistive pressure sensor that uses a protective gel to protect the piezoresistive device is susceptible to lead wire failure by vibration-induced waves in the protective gel. Such waves can be reduced and the device made more robust by the use of three-dimensional structures in the gel, which are configured to reduce and/or re-direct vibration-induced pressure waves in the gel. The structures are referred to as 'breakwaters' in that they protect lead wires and lead wire connections from wave fronts and the damage that wave-induced pressure on the lead wires causes.
