Abstract
An apparatus for depositing and/or jetting viscous medium on a surface of a workpiece includes at least two depositing head assemblies. The at least two depositing head assemblies are configured to move in three dimensional space. The at least two depositing head assemblies are also configured to at least one of concurrently and simultaneously deposit the viscous medium on the workpiece.
Claims26
A method for depositing viscous media on a workpiece, the method comprising:
- moving at least two depositing head assemblies in three dimensional space, the moving including
- moving a first of the at least two depositing head assemblies along a first beam arranged above a platform holding the workpiece, and
- moving a second of the at least two depositing head assemblies along a second beam arranged above the platform and in parallel with the first beam;
- and
- depositing the viscous media on the workpiece at least one of concurrently and simultaneously by the at least two depositing head assemblies, the depositing including
- shooting droplets of mutually different types of viscous media, at least one of the mutually different types of viscous media is a solder paste and at least one other of the mutually different types of viscous media is not a solder paste.

A method for depositing viscous media on a workpiece, the method comprising:
- moving the workpiece in a first direction by transferring the workpiece from a first supporting arrangement to a second supporting arrangement;
- moving a depositing head assembly in at least the first direction and a second direction, the moving of the depositing head assembly in the first direction at least compensating for the movement of the workpiece in the first direction;
- and
- depositing, by the depositing head assembly, the viscous media on the workpiece at least one of concurrently and simultaneously while the workpiece moves in the first direction between the first and second supporting arrangement and while the depositing head assembly moves in the first and the second directions, the depositing including
- shooting droplets of mutually different types of viscous media, at least one of the mutually different types of viscous media is a solder paste and at least one other of the mutually different types of viscous media is not a solder paste.

A linescan jetting method for depositing viscous media a workpiece, the method comprising:
- moving the workpiece in a first direction;
- first depositing, by a first depositing head assembly movably fixed to a first beam, a first viscous medium on the workpiece while moving the first depositing head assembly along the first beam in a second direction, which is perpendicular to the first direction;
- and
- second depositing, by a second depositing head assembly fixed to a second beam, a second viscous medium on the workpiece while moving the second depositing head assembly along the second beam in the second direction;
- wherein
- the first depositing and the second depositing is performed at least one of concurrently and simultaneously,
- the first viscous medium and the second viscous medium are mutually different types of viscous media,
- the first viscous medium is a solder paste, and
- the second viscous medium is not a solder paste.

A linescan jetting method for depositing viscous media on a workpiece, the method comprising:
- moving the workpiece in a first direction;
- moving a depositing head assembly in the first direction to compensate for the movement of the workpiece in the first direction, the depositing head assembly movably fixed to a beam;
- and
- depositing, by the depositing head assembly, mutually different types of viscous media on the workpiece while moving the workpiece and the depositing head assembly in the first direction and moving the depositing head assembly along the beam in a second direction, which is perpendicular to the first direction, the depositing mutually different types of viscous media on the workpiece including
- at least one of concurrently and simultaneously shooting droplets of the mutually different types of viscous media, at least one of the mutually different types of viscous media is a solder paste and at least one other of the mutually different types of viscous media is not a solder paste.

A linescan jetting method for depositing viscous media on a workpiece, the method comprising:
- moving the workpiece in a first direction;
- moving a single depositing head assembly in the first direction to compensate for the movement of the workpiece in the first direction, the single depositing head assembly movably fixed to a beam;
- and
- depositing, by the single depositing head assembly, mutually different types of viscous media on the workpiece while moving the workpiece and the single depositing head assembly in the first direction, and moving the single depositing head assembly along the beam in a second direction, which is perpendicular to the first direction, the depositing including
- shooting droplets of the mutually different types of viscous media, at least one of the mutually different types of viscous media is a solder paste and at least one other of the mutually different types of viscous media is not a solder paste.
