Embodiment Construction

[0028] The term "part" is used herein to refer to a broad category of parts that can be "picked" and "placed" using a pick-and-place machine. Example components include semiconductor dies, capacitors, resistors, integrated circuits, packaged devices, and the like.

[0029] The term "board" as used herein refers to a broad class of substrates onto which components may be placed using a pick and place machine. Example boards (also referred to as substrates) include printed circuit boards, lead frames, wafers, glass substrates, metal plates, and the like.

[0030] The invention relates to a method of positioning a component at a desired position on a board, whereby said component is picked up by means of a nozzle of a movable placement unit of a pick-and-place machine. The placement unit includes sensors. After determining the orientation of the part relative to the nozzle, the part is placed in the desired position on the plate with the correct orientation. The invention also...

Abstract

Methods are provided for positioning components at desired locations on the board. The method comprises the steps of: (a) picking up a part with a nozzle of a movable placement unit of a pick-and-place machine; (b) conveying said part toward a plate according to a desired position; sensor data on the orientation of the nozzle; (d) acquire sensor rotation data on the orientation of the nozzle relative to the placement unit; (e) combine the sensor data and rotation data into a data set within the sensor; (f) send the data set from the sensor to a stationary computer and calculating correction instructions within the stationary computer; and (g) placing said components on the board according to the correction instructions from the stationary computer.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 268578, filed December 17, 2015, the contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a method of positioning a component at a desired position on a board, whereby the component is picked up by a nozzle of a movable placement unit of a pick and place machine. The invention also relates to a pick and place machine and a sensor for such a pick and place machine. Background technique [0004] Using a pick-and-place machine, parts can be rotated with the nozzle (about the nozzle's axis of rotation) in the φ direction and in the direction opposite to the φ direction, and can be rotated with the nozzle in (i) an XY plane extending perpendicular to the axis of rotation and ( ii) Movement in the Z direction extending parallel to the axis of rotation. [0005] Several methods are known to determine th...
