Electrical interconnects are an intrinsic part of any electronic system. The interconnect has to perform on a wide range of substrates and under wide range of environmental conditions, and survive induced stresses from thermal, mechanical, corrosive and electrical factors. In many instances the capability of the interconnect is a road block to realising the full performance of the functional circuit.
What we do
We investigate interconnect properties and develop metrological techniques to characterise performance, frequently in multiple domains. Our research is focused on the emerging technologies within printed electronics, harsh and high temperature electronics, wearable technology and electrochemical performance in coating barrier systems:
- Developing combinatorial mechanical, thermal and electrical measurement techniques, and inventing measurement instruments where necessary
- Developing measurement technology to characterise degradation by electrochemical corrosion in sub-micron aqueous films
- Developing microstructural and materials understanding to describe the properties in complex interfacial structures
- Developing metrology in smart textiles and printed electronics
Industry roadmaps and sustainability are driving technology into new material sets, whereas the PCB use to be plated copper and solder joints, all manner of substrates from paper to LCP, and interconnects from ink, adhesives and sintered nano-powders are being used. Operating conditions are becoming increasingly harsh, with higher temperatures, and corrosive gases. New innovations in smart textiles and labels call for metrology innovations. NPL is working with partners to provide the tools to move the industry forward.
Products & Services
- Scanning Acoustic Microscopy (SAM) is a technique for studying buried solid interfaces of dissimilar materials.
- NPL's Electronic Interconnection Group will be presenting a series of technical webinars over the coming months.
- A new instrument, Interconnect Properties Test machine (IPTM), has been designed and built at NPL. IPTM, with a bespoke sample geometry, permits small solder volumes to be studied in pure shear.
