POINTING DEVICE FOR PORTABLE DEVICE AND MANUFACTURE METHOD THEREOF

摘要

PURPOSE: A manufacturing method of a pointing device is provided to reduce a manufacturing cost and failure rate by accurately combining devices. CONSTITUTION: An image sensor(130) is combined with a substrate(140). An optical source unit(110) is combined with the substrate through an FPCB(Flexible Printed Circuit Board). A chimney structure is applied to the top of the image sensor. The optical source unit is molded in an EMC(Epoxy Molding Compound). The optical source unit is fixed to a concave part.
