Improving Electronic Reliability - Through Product and Process Qualification at NPL (Webinar series)



NPL's Electronic Interconnection Group is presenting a new series of technical webinars in 2015.

Recordings of previous webinars are available here

This Group is internationally recognised for its practical and innovative work on lead-free reliability, PCB interconnection failures, tin whisker migration and conformal coating research.

These FREE online webinars provide the opportunity to draw on years of practical experience without the participant needing to leave his/her desk - to participate, all that is needed is a phone line and Internet access. Please note that registration is essential.

Each webinar lasts approximately 60 mins (and is limited to 100 delegate/company registrations). After the webinar, participants receive a copy of all of the slides and a listing of all relevant technical reports which can be downloaded for FREE.

Please note that all webinars are at UK time - check local time in other countries here




Laser & Robotic Iron Soldering for Electronics Assembly
Presented by Bob Willis NPL Defect Database Co-ordinator

Monday 19 January 2015 (14:30 hrs UK time)

Book your place here

Over the past few years there has been a lot of discussion on the need for higher temperature materials and expanding the use and knowledge of high temperature assembly techniques. In many industries there is also increasing interest in automating these soldering processes rather than the traditional manual soldering techniques for small and medium volume. When we start to talk about high temperature electronics it is not just the solder alloy but all of the materials that go to produce an electronic assembly. Substrates, components, connectors, cables and solder need to be examined; the needs of the assembly process also require careful consideration.

Often, due to the smaller volumes, many companies who require high temperature capability have used manual soldering techniques, particularly for through hole. Typically, the industries affected by these hostile working conditions include aerospace, automotive, petrochemical and military. Laser soldering and robotic iron systems are increasingly being investigated for use in factories and, due to the limited availability of information, NPL has started looking at the benefits of these techniques.

Topics covered:

  • Reasons for laser and robotic soldering
  • Equipment considerations
  • Soldering with high temperature solder alloys
  • Intermetallic formation
  • Impact of ageing
  • Inspection of solder joints
  • Common process defects

This webinar will run for between 45-60 minutes, with a Q&A session. A copy of each of the slides presented and links to NPL reports will be provided after the webinar.



Smart Textiles for Wearable Technology
Presented by Roya Ashayer-Soltani, NPL

Monday 16 March 2015 (14:30 hrs UK time)

Book your place here

There is an increasing demand for wearable electronics from industries such as sport and fitness, consumer electronics, medical and healthcare applications. Smart textiles with wearable technology have the potential to change the way we manage our health, respond to emergency, communicate and entertain ourselves.

Currently, weaving or knitting a metal wire is the most commonly-used method for making a conductive textile. However, true wearable technology should be integrated within the clothing with maximum comfort and minimum visibility. The conductive textile solution we present here could make this possible. Currently, there are significant challenges for wearable electronics which needs to be overcome, e.g. a critical performance metric for future smart textiles is the ability to withstand multiple wash cycles. Also, there are environmental concerns regarding the release of metals in the form of nanoparticles.

This webinar will provide information regarding existing technologies, developments and challenges facing the wearable market.

Topics covered:

  • Why wearable technology?
  • Market opportunities
  • Limitation of existing processes
  • Available manufacturing techniques
  • Advance techniques fabric technology

This webinar will run for between 45-60 minutes, with a Q&A session. A copy of each of the slides presented and links to NPL reports will be provided after the webinar.
