Abstract
A dual axis linear motion system utilizing one or more printed circuit boards embedded within a stage wherein the system components, including the controller, drive, and controller, may be mounted to a printed circuit board (PCB), and the electrical communications between the system components and the power to the system components are supplied through traces or etchings on the printed circuit board, thereby omitting the need for additional power and communication cables.

A dual axis linear motion system comprising:
- a base having an upper surface;
- a printed circuit board having an upper surface and a lower surface, wherein the printed circuit board is configured to move back and forth along a first linear direction relative to the base;
- a moving carriage having a lower surface, wherein the moving carriage is configured to move back and forth along a second direction relative to the printed circuit board, wherein the second direction is substantially orthogonal to the first direction, and wherein the printed circuit board is disposed between the upper surface of the base and the lower surface of the moving carriage;
- a first linear motor configured to move the printed circuit board in the first direction, wherein the first linear motor comprises at least one first motor coil and at least one first motor magnet;
- a second linear motor configured to move the moving carriage in the second direction, wherein the second linear motor comprises at least one second motor coil and at least one second motor magnet;
- an electronic motion controller configured to provide motion commands in order to control the movement of the printed circuit board and the moving carriage;
- and
- an electronic drive configured to translate commands from the electronic motion controller, wherein the electronic motion controller is configured to supply at least one first current to the first motor coil, and wherein the electronic motion controller is configured to supply at least one second current to the at least one second motor coil;
- wherein the electronic motion controller and electronic drive are mounted on the printed circuit board;
- wherein the at least one first motor magnet is mounted on the upper side of the base, and wherein the at least one first motor coil is mounted on the lower side f the printed circuit board.
