Portable electronic device and image-capturing module thereof, and carrier assembly thereof

A carrier assembly, comprising:

• a circuit substrate for carrying at least one electronic component, wherein the at least one electronic component is electrically connected to the circuit substrate;
• a package structure disposed on the circuit substrate and in contact with the at least one electronic component;
• a holder structure disposed on the package structure;
• and
• a reinforcing structure disposed on the circuit substrate, the package structure and the reinforcing structure being disposed on two opposite surfaces of the circuit substrate, wherein the package structure has a dustproof coating disposed on an outer surface thereof, and the holder structure is disposed on the dustproof coating of the package structure without contacting the circuit substrate, and wherein the package structure has a single package body and a light-transmitting window passing through the single package body, and the single package body has a surrounding light-guiding surface disposed inside the light-transmitting window.

A portable electronic device using an image-capturing module, characterized in that the image-capturing module comprises:

• a circuit substrate having a top surface and a bottom surface;
• an image-sensing chip electrically connected to the circuit substrate, wherein the image-sensing chip has an image-sensing area;
• at least one electronic component disposed on the top surface of the circuit substrate and electrically connected to the circuit substrate;
• a package structure disposed on the top surface of the circuit substrate and in contact with the at least one electronic component;
• a lens assembly including a holder structure disposed on the package structure and a lens structure being held by the holder structure and corresponding to the image-sensing area;
• and
• a reinforcing structure disposed on the bottom surface of the circuit substrate to surround the image-sensing chip, and a thickness of the reinforcing structure is greater than a thickness of the image-sensing chip, wherein the reinforcing structure includes a reinforcing board surrounding the image-sensing chip and a receiving space passing through the reinforcing structure, and the whole image-sensing chip is received inside the receiving space of the reinforcing structure.
