Flexible Circuits




  • NPL research is focused upon characterising nano-interconnects for electronic applications.
  • Electronics are increasing being required to operate above 150ºC, in applications which include avionics, oil drilling and automotive. NPL is developing techniques for characterising interconnect systems at elevated temperatures.
  • Improving manufacturability and lifetime prediction of plastic electronics systems.
  • NPL is at the forefront of activities in the UK to investigate technical and implementation challenges facing the industry changing from Sn/Pb solders to the lead-free alternatives.
  • NPL research is focused upon developing solderability testing of lead-free alloys in both air and inert (N2) atmospheres.
