An method for operating an object printing system printer prints electrical circuits on non-planar areas of objects and accurately places electronic components within the printed circuits. The method includes operation of a direct-to-object printer to form an electrical circuit on an object secured within the direct-to-object printer and operation of an electronic component placement system to retrieve an electronic component and install the electronic component in the electrical circuit on the object secured within the direct-to-object printer in response to a generation of a signal by the direct-to-object printer for the electronic component placement system that indicates the electronic component is to be installed in the circuit on the object secured within the direct-to-object printer.

A method for processing substrates, in particular wafers, masks or flat panel displays, with a semi-conductor industry machine, wherein a computer-supported process is used to determine the presence and/or position and/or orientation of the substrate. Further, a system designed to execute the method. The computer-supported process includes an artificial neural network.

A method of transferring micro-devices includes selectively treating a first adhesive layer to form a treated portion and an untreated portion while micro-devices are attached the first adhesive layer. A second adhesive layer on a second surface is placed to abut the micro-devices. The first adhesive layer is exposed to illumination in a region that overlaps at least some of the treated portion and at least some of the untreated portion. Exposing the first adhesive layer to illumination neutralizes the at least some of the untreated portion to create a neutralized portion that is less adhesive than an exposed area of the treated portion. The first surface is separated from the second surface such that micro-devices in the treated portion remain attached to the first surface and micro-devices in the neutralized portion are attached to the second surface and separate from the first surface.

A method of transferring micro-devices includes attaching micro-devices to one surface of a first body with a first adhesive layer, and selectively forming a masking layer on an opposite surface of the first body. A second adhesive layer on a second body is placed to contact the plurality of micro-devices. The first adhesive layer is exposed to illumination through the first body to create a neutralized portion while the masking layer blocks the illumination from reaching some of first adhesive layer to provide a less exposed portion that is more adhesive than the neutralized portion. The first surface is separated from the second surface such micro-devices on the less exposed portion of the first adhesive layer remain attached to the first surface and micro-devices corresponding to the neutralized portion attach to the second body and separate from the first surface.

An adjustment jig for performing position alignment of nozzle holders, including: multiple positioning pins including a primary insertion section configured such that multiple nozzle holders of a primary side device are insertable into the primary insertion section and a secondary insertion section configured such that multiple nozzle holders of a secondary side device are insertable into the secondary insertion section; and a board member configured such that the multiple positioning pins protruding to an opposite side to the primary insertion section and the secondary insertion section can be attached at a specified fixing position via a fixing section, a position of which is adjustable.

A calculation device for a work machine comprising a holding head including a holding tool configured to hold a lead component comprising a lead and a body and a moving device configured to move the holding head, the calculation device calculating a release position of the lead component held by the holding tool, when the work machine mounts the lead component on a board by inserting the lead of the lead component held by the holding tool into a hole formed on the board by operating the moving device.

The first surface is separated from the second surface such that micro-devices in the treated portion remain attached to the first surface and micro-devices in the neutralized portion are attached to the second surface and separate from the first surface.

A mapping device includes: a substrate engraved with an alignment pattern; an electrostatic chuck under the substrate and in contact with the substrate; and an anti-separation frame on the substrate and preventing the substrate from being separated.
