TLDR
In this paper, an apparatus and a method for manufacturing electrical and optical materials by ink-jet printing of electronic ink(s) onto a flexible substrate is described, where the substrate can be rewinded prior to deposition of the second ink, or to reverse the feed/takeup direction of the rolls.Abstract:
An apparatus and a method for manufacturing electrical and optical materials by ink-jet printing of electronic ink(s) onto a flexible substrate are provided The apparatus includes a flexible substrate, a first roll and a second roll, a printing head for depositing a electronic ink onto the substrate according to a predetermined pattern, and a drying station for drying an amount of deposited electronic ink Each roll is reversibly configured for feed or takeup of the substrate When dry, the deposited electronic ink forms one of an electronic material, an optical material, a display, and a fuel cell electrode The apparatus may also include a second printing head configured for depositing a second electronic ink onto the substrate after the first ink has dried The apparatus may be configured to rewind the substrate prior to deposition of the second ink, or to reverse the feed/takeup direction of the rollsread more

Method and apparatus for assembling electric components on a flexible substrate as well as assembly of an electric component with a flexible substrate
TL;DR: In this paper, a method for assembling a component (30) with a flexible substrate (10), the component having electric contacts (31), comprises the steps of - placing the component on a first main side (11) of the substrate, applying a machine vision step to estimate a position of the electric contacts, depositing one or more layers (32) of an electrically conductive material or a precursor thereof, said layer extending over an area defined by the component to laterally beyond said area, calculating partitioning lines depending on the estimated position of electric contacts.
