Flexible electronic circuit board for a multi-camera endoscope

An electronic assembly for a medical device, wherein the electronic assembly comprises:

• a first optical assembly;
• a first illuminator;
• a second illuminator;
• a first circuit board configured to support the first optical assembly, the first illuminator, and the second illuminator, wherein the first circuit board is flexible so as to allow the first circuit board to be folded from an unfolded configuration to a folded configuration, and wherein the first circuit board includes:
• a distal portion including:
• a first planar portion facing a distal direction, wherein the first optical assembly is mounted to the first planar portion;
• a second planar portion positioned distal from the first planar portion, wherein the first illuminator is mounted to the second planar portion;
• and
• a third planar portion positioned distal from the first planar portion and spaced from the second planar portion, wherein the second illuminator is mounted to the second planar portion;
• and
• a circuit board holder configured to hold the first circuit board in the folded configuration, wherein the circuit board holder includes:
• a first end face at a distalmost end of the circuit board holder, wherein the first end face is coupled to the second planar potion;
• a second end face at a distalmost end of the circuit board holder, wherein the second end face is coupled to the third planar potion;
• a first intermediate face extending proximally from the first end face and facing the first optical assembly;
• and
• a second intermediate face extending proximally from the second end face and facing the first optical assembly;
• wherein the first optical assembly extends between the first end face and the second end face.
