Title: Device for precise assembly of light receiver on substrate

Abstract: A device includes a vacuum nozzle, a driver, a light source, a measuring unit, and a controller. The vacuum in the nozzle picks up and holds a light receiver. The driver drives the nozzle to press the light receiver onto a substrate such that the light receiver is electrically connected to the substrate. A light source in the nozzle illuminates the light receiver causing the generation of a first electrical signal. The measuring unit measures a second electrical signal that is a part of the first electrical signal, and the driver is controlled drive the nozzle to press harder until the second electrical signal stops increasing, the degree of conductivity between the light receiver and the substrate being then at the maximum.
