High Speed Dispensing with Novel 6” Print Head

Towards 3D-lithium ion microbatteries based on silicon/graphite blend anodes using a dispenser printing technique

“…For industrial dispenser process speeds the shear rate is surpassing 5000 s À1 , which cannot be measured with commercial rotational rheometers due to signicant sample spillage at high rotation speeds. 23,36 Here all paste samples show similar viscosities at high shear rates (see Fig. 3a) but differ signicantly during dispensing experiments in terms of their printed line geometry.…”

Conductive Highly Filled Suspensions for an Electrochemical Dispensing Approach to Pattern Full-Area Thin Metal Layers by Physical Vapour Deposition

“…The ECD setup consists of a commercially available dispensing machine combined with minor adjustments to provide a necessary electrical circuit. The potential throughput rate of ECD is similar to the state of the art flatbed screen printing and dispensing process of commercial available metal pastes 5,6 . Over the last 15 years the PV industry is demonstrating how a systematic approach for paste development and rheological improvements contributed significantly to a further optimization of printed line geometries.…”

“…The volume flow rate of each paste sample is generated by a constant pressure applied to the cartridge. The experiment is done similarly to metallization of silicon solar cells by the parallel dispensing approach, described in literature 5,9,12,13 . Depending on the rheological parameters of each dispensing paste, it is necessary to evaluate the correct pressure in order to ensure a sufficient volume flow rate for a given speed v x of the table robot.…”

Increasing the Effective Area of Small‐Sized CIGS Modules by Printed Ag Front Contacts

“…Multinozzle print heads with up to 130 parallel nozzles guarantee high throughput rates, which are especially essential in the photovoltaic market. [ 25–27 ] Furthermore, the dispensing approach enables a very uniform narrow Ag‐electrode shape which can be described by different geometrical parameters. [ 28 ] The maximum shaded area of the Ag‐electrode including any spreading is represented by the shading electrode width w shading .…”
