Abstract
A stencil printer for printing an assembly material on an electronic substrate includes a frame, a stencil coupled to the frame, the stencil having apertures formed therein, a support assembly coupled to the frame, the support assembly being configured to support the electronic substrate, a print head gantry coupled to the frame, and a print head assembly supported by the print head gantry in such a manner that the print head assembly is configured to traverse the stencil during print strokes. The stencil printer further comprises a verification system to determine whether an item placed within the stencil printer is properly installed within the stencil printer.
Claims19
A stencil printer for printing an assembly material on an electronic substrate, the stencil printer comprising:
- a frame;
- a stencil coupled to the frame;
- a support assembly coupled to the frame, the support assembly being configured to support the electronic substrate;
- a print head gantry coupled to the frame;
- a print head assembly supported by the print head gantry in such a manner that the print head assembly is configured to traverse the stencil during print strokes;
- and
- a verification system to determine whether an item placed within the stencil printer is properly installed within the stencil printer,
- wherein the print head gantry includes an elongate beam that rides along rails provided on the frame, the elongate beam of the print head gantry including at least one linear bearing that extends in a horizontal direction, and wherein the verification system includes at least one tooling member configured to move laterally on the at least one linear bearing.
A stencil printer for printing an assembly material on an electronic substrate, the stencil printer comprising:

- a stencil coupled to the frame;
- a support assembly coupled to the frame, the support assembly being configured to support the electronic substrate;
- a print head gantry coupled to the frame;
- a print head assembly supported by the print head gantry in such a manner that the print head assembly is configured to traverse the stencil during print strokes;
- and
- a verification system to determine whether an item placed within the stencil printer is properly installed within the stencil printer,
- wherein the verification system includes
- at least one tooling member configured to move laterally on at least one linear bearing of the print head gantry, the at least one tooling member includes a downwardly extending pin configured to be moved between a fully extended position and a retracted position, and
- a controller configured to move the at least one tooling member over the item and determining whether the pin of the at least one tooling member is in the retracted position.
