Abstract
An electronic control unit (ECU) includes a flexible circuit substrate having a first partition interconnected to a third partition by a second, flexible partition. The electronic control unit further includes a rigidizer having a first partition interconnected to a third partition by a second partition. When the ECU is twice folded, the second, flexible partition of the circuit substrate assumes an approximate ‘U’-shape, resulting in a reduced cracking and splitting rate than the prior art. In various embodiments of the present invention, the assumption of a ‘U’-shaped fold in the second, flexible partition of the circuit substrate is facilitated by multiple apertures in a second rigidizer partition, by a depression in a second rigidizer partition, or by non-slidably affixing a first circuit substrate partition to a first rigidizer partition via a first adhesive and non-slidably affixing a third circuit substrate partition to a third rigidizer partition via a second adhesive.
