Manufacturing method of solid-state image sensing device
View Patent ↗In a method of manufacturing a camera module having a CMOS image sensor, a semiconductor chip to serve as a light sensor is mounted on a optical-component-mounting face of a wiring substrate mother board and, after bonding wires are connected to the semiconductor chip, a lens barrel is joined to the wiring substrate mother board so as to cover the semiconductor chip. A position adjustment pin and a through hole are provided on the lens barrel and the wiring substrate mother board respectively outside a junction face between the lens barrel and the wiring substrate mother board to be used for adjusting the position of the lens barrel with respect to the wiring substrate mother board by inserting the position adjustment pin into the through hole.
1. A method of manufacturing a solid-state image sensing device comprising the steps of:
(a) preparing a wiring substrate mother board having a first face and a second face on the side opposite to said first face;
(b) mounting first electronic components over said first face of said wiring substrate mother board;
(c) encapsulating said first electronic components by using an encapsulation body;
(d) mounting second electronic components including image sensors over said second face of said wiring substrate mother board; and
(e) joining a frame to said second face of said wiring substrate mother board so as to cover said second electronic components,
wherein said frame has a position adjustment pin for adjusting the position of said frame with said wiring substrate mother board,
wherein said wiring substrate mother board has a through hole into which said position adjustment pin is to be inserted, and
