Bending machine for testing reliability of flexible electronics

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1563564

A novel bending machine has been designed and tested. It enables flexible electronics to be subjected to repeated bending with constant radius and tension. In-situ electrical characterization can give accurate analysis of lifetime distributions if sufficiently many samples are ran to failure, allowi...

Soldering of components onto a smart tag - an evaluation of the process window

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1479622

An experiment was designed using optimal design of experiments to identify the most relevant parameters in an assembly step for a smart tag; the soldering of 0402 resistors to a polyimide backplane. The parameter window was set to reflect natural variations in production, and parameter variations we...

Hygrothermal aging of flip-chip assembled MOEMS

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1458002

A flip-chip version of an optical MEMS (MOEMS) assembly is demonstrated in this work. A dummy MOEMS device is attached directly onto a traditional FR-4 board using a novel isotropic conductive adhesive (ICA) in order to minimize both fabrication costs and footprint of the assembly. The assembly solu...

Smart Tags that are exactly Reliable Enough

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1450852

Smart tags for fast moving consumer goods are among the products predicted to be part of the Internet of Everything. The tags must be extremely low cost, be fabricated in huge volumes, and have a quality accepted by the end user. Screening tests have been performed to evaluate technologies for hybri...

All-Copper Flip Chip Interconnects by Pressureless and Low Temperature Nanoparticle Sintering

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1413917

Flip chip interconnects purely made out of Cu, so-called all-Cu interconnects, have the potential to overcome the present current capacity limit of state-of-the-art solder based interconnects, while meeting the demand for ever decreasing interconnect pitches. Parasitic effects in solder based interc...
