Patent ID: 8341827

Claim:
A component mounting device suitable for placing a component on a substrate comprising a component feeding device, a component pick-and-place device comprising a nozzle, a substrate carrier, means for moving the component pick-and-place device from the component feeding device to said substrate carrier to pick up a component with said nozzle of said component pick-and-place device from said component feeding device and to place said picked-up component at a desired position on said substrate being located on said substrate carrier, a global measuring system for determining the position of said component pick-and-place device during movement of said component pick-and-place device from said component feeding device to said substrate carrier and for determining the position of said component pick-and-place device during movement of said component pick-and-place device from said substrate carrier to said component feeding device whereby said component mounting device further comprises a local measuring system, remote from said global measuring system, for substantially continually determining, in the proximity of said desired position of said component on the substrate, the position of said component pick-and-place device with respect to said substrate, during said movement of said component pick-and-place device and which local measuring system is located closer to said substrate carrier than said global measuring system.
