Image pickup device and method for manufacturing image pickup device

Abstract

The imaging device has: a plurality of miniature pins, which are arranged to protrude from the back side of the imaging surface of the imaging element; a plurality of circuit boards, which have a substrate surface on which electronic accessories can be mounted, and the substrate surface is provided with a plurality of micropins respectively. The through-hole or through-groove formed thereby; and the soldering part, it is used in the state that a plurality of circuit boards are stacked on the back side of the imaging element in a manner that makes a plurality of micropins respectively penetrate through the through-holes or through-slots of the plurality of circuit boards A plurality of micro pins and a plurality of circuit boards are fixed by soldering using pad portions adjacent to the through holes or the through grooves.

Description

technical field [0001] The present invention relates to an imaging device including an imaging element mounted on an endoscope or the like, and a method of manufacturing the imaging device. Background technique [0002] In recent years, endoscopes in which an imaging device is attached to the distal end of an insertion portion have been widely used in medical and industrial fields. [0003] Figure 13 The configuration of a conventional imaging device 100 similar to the configuration of the imaging device disclosed in JP 2008-177701 A is shown, which is attached to the distal end portion of an endoscope insertion portion. [0004] The main part of this imaging device 100 is made up of following parts: objective lens system 101, it is made of a plurality of lenses 101a-101f; Lens frame 102, it holds objective lens system 101; Element frame 104, it holds a part of imaging element 103; 105 ; a heat-shrinkable tube 106 ; a protective tube 108 covering the signal cable 107 ; and...

AI Technical Summary

Problems solved by technology

[0015] Therefore, assuming that the imaging device of the second conventional example is installed at the front end of the endoscope, the same Figure 13 In the case of the imaging device 100 in the same way, there is a disadvantage that the size of the longitudinal direction of the front end portion becomes large.

[0016] In addition, in the imaging device 100 of the first conventional example, it is difficult to sufficiently increase the strength of the connecting portion between the imaging element 103 and the FPC 110

[0017] In addition, when the first and second imaging devices are installed along the direction in which the optical axis direction of the objective lens system is perpendicular to the longitudinal direction of the tip portion, the radial dimension of the tip portion becomes larger.

[0018] In addition, in the imaging device of the above-mentioned second conventional example, the FPC on which the electronic components are mounted has the characteristics of being easy to process such as bending, and on the other hand, since the amount of bending is set within a predetermined value to avoid that each product There is a possibility of labor-intensive assembly due to adjustment operations that cause deviations, etc.
