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.

First claim

What is claimed is:

1. A linescan jetting apparatus for at least one of depositing or jetting viscous medium on a workpiece, the apparatus comprising:
a conveyor configured to carry the workpiece in a first direction;
a first set of beams extending longitudinally between opposite sides of a depositing head assembly frame;
a second set of beams extending longitudinally between the first set of beams in a direction that is perpendicular to a direction in which the first set of beams extends longitudinally, such that each beam of the second set of beams is connected at opposite ends to separate beams of the first set of beams, the second set of beams including a first beam and a second beam;
a first depositing head assembly movably fixed to the first beam, the first depositing head assembly being configured to move along the first beam in a second direction, which is perpendicular to the first direction; and
a second depositing head assembly fixed to the second beam, the second depositing head assembly being configured to move along the second beam in the second direction.

2. The apparatus of claim 1 , wherein the conveyor is configured to move the workpiece incrementally in the first direction.

3. The apparatus of claim 1 , wherein the first and second depositing head assemblies are configured to at least one of concurrently and simultaneously deposit viscous medium on the workpiece.

4. The apparatus of claim 1 , wherein the first and second depositing head assemblies are configured to move in a third direction, which is perpendicular to the first and second directions.

5. The apparatus of claim 1 , wherein the first and second depositing head assemblies are configured to at least one of,
shoot different types and/or different classes of solder pastes,
shoot droplets with different shot sizes and/or shot ranges, and
shoot droplets of various types of viscous media.
