Abstract

The invention provides an electronic component of an image sensing device, comprising: a packaging module, a lens group, a non-transparent conductive layer, a printed circuit board, and solder balls; The first conductive layer, the first protective layer and the first pad; the lens group is assembled on the packaging module; the non-transparent conductive layer is arranged on the side wall of the lens group and is electrically connected to the first conductive layer; the printed circuit board, Assembled in the encapsulation module and having a ground layer disposed inside; and solder balls disposed on the first pad and electrically connected to the ground layer. The present invention can solve the EMI problem without using a metal case for EMI protection, thereby reducing the manufacturing cost.

Description

technical field [0001] The present invention relates to an image sensing device technology, in particular to a packaging module and an electronic component with electromagnetic interference (electromagnetic interference, EMI) protection for an image sensing device. Background technique [0002] Charge-coupled device (CCD) image sensing devices and complementary metal oxide semiconductor (CMOS) image sensing devices are widely used in digital image products. Image capture techniques are also well known to consumers due to the increased usage of image sensing devices such as digital cameras, digital image recorders, camera phones and monitors, among others. [0003] An image sensing device typically includes a diode array for pixels, a control circuit, an analog-to-digital converter, and an amplifier. Regardless of whether these devices are on the same chip, such as a sensor device, or in a camera module or on a printed circuit board (PCB), preventing electromagnetic interfer...
