Abstract
An image sensor module includes a lens member, a resin frame that holds the lens member, a diaphragm formed on the lens member, an image sensor chip that receives light converged by the lens member, and a supporting board upon which the image sensor chip is mounted. The board is fixed to the bottom side of the resin frame. The diaphragm includes an opening for allowing the passage of light, and a light-shielding portion which is entirely held in contact with the lens member. The lens member is glued to the frame so that any additional fixing element such as a lens cap is unnecessary.
Claims17
An image sensor module comprising:
- a lens member including a first surface and a second surface opposite to the first surface;
- a frame that holds the lens member;
- a diaphragm formed on the first surface of the lens member, the diaphragm including an opening and a light-shielding portion;
- an image sensor chip that receives light converged by the lens member;
- and
- a board upon which the image sensor chip is mounted, the board being fixed to the frame;
- wherein the light-shielding portion of the diaphragm is entirely held in contact with the lens member.
A method of making an image sensor module, the method comprising the steps of:
- mounting an image sensor chip onto a supporting board;
- forming an intermediate assembly by fixing the board to a lens holding frame;
- fixing the intermediate assembly to an external element by reflow soldering;
- and
- fixing a lens member to the lens holding frame.
