Claim Text:
1. An encoder device for optical detection of movement and/or position, comprising: a first terminal adapted to deliver an electric measurement code signal; a first printed circuit board; a code device including a pattern; a detector mounted on said first printed circuit board, the detector and the code device displaceable relative to each other, the detector adapted to generate an electric measurement code signal in accordance with relative displacement between the detector and the code device, the detector including at least one light-sensitive semiconductor chip having a first light-sensitive chip surface and a second chip surface on opposing sides, the first light-sensitive chip surface having a first chip contact area adapted for an electrical connection, the second chip surface of the light-sensitive semiconductor chip mounted on the first printed circuit board; and a second printed circuit board positioned between the first light-sensitive chip surface of the light-sensitive semiconductor chip and the code device; wherein the second printed circuit board is adapted to allow passage of light from the code device to the first light-sensitive chip surface; wherein the second printed circuit board includes a first PCB contact area connected to the first terminal; wherein the first PCB contact area is connected to the first chip contact area by solder, electrically conducting glue, and/or ohmic contact.
