SELF-ALIGNING OPTICAL SENSOR PACKAGE

摘要

One embodiment relates to an optical navigation device. The device includes a lead frame (102) having reference features, a laser (402), a detector array (404), and an optical component (106) having alignment features (206). The laser (402) is attached to the lead frame (102) and positioned in reference to the reference features (202) of the lead frame (102). The detector array (404) is attached to the lead frame (102) and positioned in reference to the reference features (202) of the lead frame. The optical component (106) is coupled to the lead frame (102) so that its alignment features (206) register to the reference features (202) of the lead frame (102). In this way, the molded optical component (106) is passively aligned to the laser (402) and the detector array (404). Other embodiments are also disclosed.
