摘要:
A pattern of material is continuously deposited onto a substrate. The substrate and a mask are continuously brought together over a portion of a drum where a deposition source emits material. The mask includes apertures that form a pattern, and the material from the deposition source passes through the pattern of the mask and collects onto the substrate to form the pattern of material. The elongation and the transverse position of the substrate and the mask may be controlled. Pattern elements of the substrate and of the mask may be sensed in order to adjust the elongation and/or the transverse position of the substrate and/or mask to maintain a precise registration. Furthermore, the apertures may have a least dimension on the order of 100 microns or less to thereby create features on the substrate having least dimensions on the order of 100 microns or less.

Methods and systems for forming layered electronic devices on a flexible, elongated substrate are described. The layered electronic devices include at least one electronically or optically active layer. Deposition of one more layers of the electronic devices occurs as the flexible substrate is moved through one or more deposition stations. At each deposition station the substrate is aligned with an aperture mask having apertures arranged in a pattern. The aperture mask and the substrate are brought into proximity over a portion of a circumference of a rotating drum. A layer of the layered electronic devices is formed by deposition of material through the apertures of the aperture mask. At each deposition station, registration between at least two layers of the layered electronic devices is maintained.

A web-handling machine frame, at least partially built from reconfigurable interconnected blocks having precision alignment points. From such blocks, modular equipment web-handling lines for web-handling operations can be constructed ad hoc with their shaft mounted web-contacting devices in tram without the need for separate alignment procedures.

A manufacturing system includes a sensing system that provides high-resolution feedback for web guiding and tension control. The system may be especially useful for web material that is manufactured to include micro-replicated structures with micron size scale. A micro-replication station forms a pattern of micro-replicated lenses on a web material. The sensing system illuminates a measurement area on the web material and detects an angular distribution of light exiting a set of the micro-replicated lenses within the first measurement area. A control system that adjusts at least one process control parameter of the transport system based on the detected angular distribution.
摘要:
A method of applying a conductive pattern of metal onto a web of indefinite length material. This method includes applying a metal containing composition onto the web in a predefined pattern, providing a roll having a very low thermal mass, and conveying the patterned web around the roll while simultaneously applying heat energy to the metal containing composition thereby converting the metal to a conductive pattern. This allows for flexible circuitry to be fabricated in an inexpensive roll-to-roll process.
摘要:
A method of controlling a moving web in relation to a selected transverse position comprising positioning a first positioning guide proximate a second positioning guide wherein the second positioning guide has a mechanism for positioning the web having minimal backlash. The web is passed through the first positioning guide and the second positioning guide. A sensor detects the transverse position of the moving web at the second positioning guide. The sensor transmits the transverse location of the web at the second positioning guide to a controller. The controller manipulates a zero-backlash actuator wherein the zero-backlash actuator is coupled to the second positioning guide such that the transverse position of the web is controllable to within a preselected dimension of the selected transverse position.
摘要:
An apparatus for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll, a second pattered roll, and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the opaque web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 micrometers.

A microreplicated article is disclosed. The article includes an opaque web having first and second opposed surfaces. The first surface includes a first microreplicated structure having a plurality of first features. The second surface includes a second microreplicated structure having a plurality of second features. The first microreplicated structure and the second microreplicated structure retain registration within 100 micrometers.
