A new technique for building stochastic clustered-dot screens is being proposed. A large dither matrix comprising thousands of stochastically laid out screen dots is constructed by first laying out the screen dot centers. Screen dot centers are obtained by placing discrete disks of a chosen radius at free cell locations when traversing the dither array cells according to either a discretely rot...

FlexTrail printing has been invented and developed for (fine-line) of various fluids, e.g., particle-based metal-containing etchants, liquid-phase pyrophoric media. Compared to other techniques, is highly independent the fluids’ viscosity. Using this approach, feature sizes 10 μm below are reached. This work utilizes as a direct metallization method silver-nanoparticle-based front electrodes on...

Since the discovery of carbon nanotubes (CNTs), researches of field emission display (FED) have been mainly focused on it, because of their high-aspect configuration, low work function, high mechanical stability and high conductivity. For CNTs to become a viable engineering material for FED applications, efficient assembly and integration processes for large size are required that are currently...

Appendix 1-Experimental Details Preparation of the conductive adhesive tracks was accomplished by first mechanically mixing a typical thermoset type of adhesive test vehicle with a loading between 78-85 wt% of silver-plated copper to form a uniform paste. The composition is then applied onto a substrate to form conductive traces or electronic circuitry. Usual methods of applying the composition...

This study is to develop a micromachining technology for a light guidepanel(LGP) mold, whereby micro dot patterns are formed on a LGP surface by a singleinjection process instead of existing screen printing processes. The micro powder blastingtechnique is applied to form micro dot patterns on the LGP mold surface. The optimalconditions for masking, laminating, exposure, and developing processes...

The low level doping of a selective emitter by etch back is an easy and low cost process to obtain a better blue response from a solar cell. This work suggests that the contact resistance of the selective emitter can be controlled by wet etching with the commercial acid barrier paste that is commonly applied in screen printing. Wet etching conditions such as acid barrier curing time, etchant co...

Abstract Conventional electronics have been highlighted as a very unsustainable technology; hazardous wastes are produced both during their manufacturing but also, due to limited recyclability, end of life cycle (e.g. disposal in landfill). In recent years additive processes (i.e. screen printing) attracted significant interest more sustainable approach electronic (printed electronics). Despite...

In the last years efforts were made to overcome the widespread screen printing metallization technique to reduce shading of the front side, increase the finger conductivity, and improve the contact properties of the metallization of crystalline silicon solar cells. A promising approach is plating via wet chemical metal deposition. Hereby, the metals nickel as contact layer and copper or silver ...

This paper describes the fabrication and the characterization of an original example of a miniaturized resistive-type humidity sensor, printed on flexible substrate in a large-scale manner. The fabrication process involves laser ablation for the design of interdigitated electrodes on PET (Poly-Ethylene Terephthalate) substrate and a screen-printing process for the deposition of the sensitive ma...
