DETAILED DESCRIPTION OF THE INVENTION

The present invention will be fully described with preferred embodiments and accompanying drawings. It should be understood beforehand that any person familiar with the skill is able to make modification to the invention described and attain the same effect, and that the description below is a general representation to people familiar with the skill and should not be construed as a limitation on the actual applicable scope of the present invention.

Referring to FIG. 1A and FIG. 1B are the top and button exploded perspective view of the electronic component and the printed circuit board (PCB). The present invention provides an electronic actuator 10 of an electronic module and a flexible printed circuit board (PCB) 20. The electronic actuator 10 includes a plurality of pins 11, whereas the flexible PCB 20 includes a first surface 22 and a second surface 23. The first surface 22 includes a plurality of first electrical contacts 21a corresponding to a plurality of pins 11 of the electronic actuator 10. The second surface 23 includes a plurality of second electrical contacts 21b configured and connected to the first electrical contacts 21a, whereas the second electrical contact 21b includes pins for circuit layout on the second surface 22 of the PCB 20.

Referring to FIG. 2 and FIG. 3 are perspectives showing the assembly of the electronic component and the printed circuit board (PCB), and the method of fabricating an electronic module having a side contact made according to the present invention. Each of the pins 11 of the electronic actuator 10 is electrically connected to each of the first electrical contacts 21a on the first surface 22 of the PCB 20, with an edge of at least a side of the second surface 23 of the PCB 20 bending to the first surface 22, thereby forming an electronic module 1 having a side contact through the second electrical contact 21b.

The method disclosed in the present invention can be applied to the method of fabricating image sensor modules, and leads to obvious outstanding performance. The present invention first provides an electronic actuator 10, which is an image chip. The image chip includes a plurality of the pins 11, and the flexible PCB 20 includes a first surface 22 and a second surface 23. The first surface 22 includes a plurality of first electrical contacts 21a corresponding to a plurality of pins 11 of the electronic actuator 10, whereas the second surface 23 includes a plurality of second electrical contacts 21b configured and connected to the plurality of first electrical contacts 21a. The second electrical contact 21b has pins available for designing layout on the second surface 22 of the PCB 20.

It is to be noted that the PCB 20 is cross-shaped, and four sides of the PCB 20 are bended to the first surface 22 with a right angle to envelop the image chip, thereby an image module having a side contact will be formed through the layout of the second electrical contact 21b.

Referring to FIG. 4A to FIG. 4D are the schematic views showing the method of fabricating an image sensor component. According to the embodiment, a method of fabricating an image sensor module applies the method disclosed in the present invention. Wherein the image sensor module 1 is placed in a mold 30, then the mold 30 is removed after stuffing is added to the mold to form an image sensor module 1′ and install the lens module 31. Accordingly, the cutting steps of the PCB fabricating process will be removed, therefore the production cost can be reduced, the problem of designing circuit layouts on a limited unit area of miniaturized modules can be resolved, and the image sensors can be made smaller and thinner.

It is to be noted that the PCB 20 can be designed into T-shaped or L-shaped, depending on the needs of designers, in order to save materials and lower production costs. Also, the circuit designer can decide which side of the PCB 20 to be bent to the first surface 22 so as to envelop the electronic actuator 10.

It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
