A feasibility study of roll to roll printing on graphene

Roll to roll process is one of the famous printing techniques that are possible to create graphic and electronic device on variable substrate by using conductive ink. Graphene is an example of material that can be used as printing ink which usually used in producing micro-scale electronic devices. Here, it is proposed that extending roll to roll printing technique into the multiple micro-scale printing fine solid line onto substrate by using graphene as a printing ink. Flexography is a high speed roll to roll printing technique commonly used in paper printing industry. And this study elaborates the feasibility of graphene as a printing ink use in combination of flexography and micro-contact or micro-flexo printing for micro fine solid line. This paper will illustrates the review of graphene in producing multiple micro-solid lines printing capability for the application of printing electronic, graphic and bio-medical.

Exploration of Fine Lines Profile Effects in Flexographic Printing

Line profile is an important consideration in printing functional devices particularly in printing very fine line for electronic applications. Since laser machining provides the opportunity to apply extreme fine lines with different profiles where unachievable mechanically. Laser ablated printing plate are costly to produce, hence it is appropriate to investigate this within a computational framework beforehand. Therefore several designs will be investigated with different geometry as the variables using both linear elastic and non linear hyperelastic models. The results exhibits that finite element analysis serves appropriately as an exploration tool where it worked well with experimental results.

Angle resolved x-ray photoelectron spectroscopy (ARXPS) analysis of lanthanum oxide for micro-flexography printing

Micro-flexography printing was developed in patterning technique from micron to nano scale range to be used for graphic, electronic and bio-medical device on variable substrates. In this work, lanthanum oxide (La2O3) has been used as a rare earth metal candidate as depositing agent. This metal deposit was embedded on Carbon (C) and Silica (Si) wafer substrate using Magnetron Sputtering technique. The choose of Lanthanum as a target is due to its wide application in producing electronic devices such as thin film battery and printed circuit board. The La2O3 deposited on the surface of Si wafer substrate was then analyzed using Angle Resolve X-Ray Photoelectron Spectroscopy (ARXPS). The position for each synthetic component in the narrow scan of Lanthanum (La) 3d and O 1s are referred to the electron binding energy (eV). The La 3d narrow scan revealed that the oxide species of this particular metal is mainly contributed by La2O3 and La(OH)3. The information of oxygen species, O2- component from O 1s narrow s...

Cost Reduction Through Value Engineering Practices in Manufacturing Assembly

Value Engineering (VE) is important tool to company in global market competition to providing a demand. VE process can provide for company continued growth and prosperity if applied properly. VE is defines as the systematic application of recognized techniques, which identify the function of product or service, establishes a monetary value for that function and provides the necessary function reliability at the lowest overall cost. This paper will presents a process on how to apply VE tools in manufacturing company. Therefore, we would like to study the application of VE approach method and at the same time investigating how much cost reduction can be done. The function of product will be defining and cost reduction is suggested by proposing alternative method to achieve that function. However the function quality is never degrading. The result is showed that 60% cost reduction can be proposed.

An Investigation onto Polydimethylsiloxane (PDMS) Printing Plate of Multiple Functional Solid Line by Flexographic

Recently low cost production is vital to produce printed electronics by roll to roll manufacturing printing process like a flexographic. Flexographic has a high speed technique which commonly used for printing onto large area flexible substrates. However, the minimum feature sizes achieved with roll to roll printing processes, such as flexographic is in the range of fifty microns. The main contribution of this limitation is photopolymer flexographic plate unable to be produced finer micron range due to film that made by Laser Ablation Mask (LAMs) technology not sufficiently robust and consequently at micron ranges line will not be formed on the printing plate. Hence, polydimethylsiloxane (PDMS) is used instead of photopolymer. Printing trial had been conducted and multiple solid lines successfully printed for below fifty microns line width with no interference between two adjacent lines of the printed images.

The result shows that CNT water base ink is suitable with PDMS printing plate in printing fine solid lines image.
