    摘要: An image sensor package module with a leadless leadframe between chips includes a chip carrier, an image sensor chip, an integrated circuit chip, and a flexible printed circuit board. The chip carrier comprises a leadless leadframe and a pre-molded body. The leadless leadframe has a plurality of leads. The pre-molded body is completely filled among the leads and has a dam on the upper surfaces of the leads. The upper surfaces and lower surfaces of the leads are exposed on the pre-molded body. The image sensor chip is attached to the chip carrier inside the dam and electrically connected to the upper surfaces of the leads. The integrated circuit chip is mounted on the lower surfaces of the leads via bumps. The flexible printed circuit board is electrically connected to the leads for signal transmission.
