QFN/LGA Contamination Testing with SIR & Saturation Testing

Welcome to this Bob Willis “Defect of the Month” video on QFN/LGA reliability This month we talk about QFN contamination testing with SIR and New NPL Saturation Testing. Results and testing procedures are available from NPL Defect of the Month is a series of videos originally produced for and featured as part of the NPL/IPC video library for the IPC website with examples taken from the NPL Defect Database http://defectsdatabase.npl.co.uk/ Over the last couple of years there have been over 40 clips produced to assist engineers and training technicians on common process issues the videos are also featured on our LinkedIn Group page Assembly Soldering Inspection Defects https://www.linkedin.com/groups/13513466 For help with your process defects and failures see http://www.bobwillis.co.uk/consultancy/ For our regular online webinars see http://www.bobwillis.co.uk/events/

Bob Willis Diving in Lanzarote September 2017

You do not get the same volume of fish as in the Caribbean and its colder to dive but very clear water. The main reason for me on this trip was to dive on the sculpture park just like the one in Grenada and Mexico Yes would dive again as there is lots more to see if I get the opportunity

Bob Diving in Grand & Little Cayman December 2017

Diving was great fun this year with lots to see and video. I would always go back to Little Cayman again and again

SMTA Europe Electronics in Harsh Environments Pre Conference Webinar

Electronics in Harsh Environments Conference 24-26 April 2018 Crowne Plaza Amsterdam - Schiphol Building on the successful Contamination, Cleaning and Coating Conference in 2017, SMTA Europe will host the Electronics in Harsh Environments Conference on 24-26 April 2018 in Amsterdam, Netherlands. The conference will focus on building reliable electronics used in power electronics and harsh environments to book visit https://www.smta.org/harsh/register_now.cfm Thermal, power and signal integrity requirements can present challenges when on devices that operate within harsh environments. Component integration, paired with a growing complexity of the package architectures, larger form factors and higher interconnection densities increase the risk of in-field failures. Over powering or over heating of a device can have serious consequences including internal package failure, down-stream device errors and second level interconnect solder joint failures. Soldering residues are more problematic, and if not understood, can result in both intermittent and complete device failure This conference tackles the challenges and best practices for building reliable electronic devices that will perform to design standards when used in harsh environments. Specific topics include building reliable high density assemblies, power electronics, electric hybrids, product assembly challenges, cleaning, coating, process control, and monitoring and tracking production hardware. Challenging areas such as high temperature soldering, solder material advances, and new standards will be presented

Bob Diving in Grand & Little Cayman December 2017 Update

Diving was great fun this year with lots to see and video. I would always go back to Little Cayman again and again as the fish life, coral and diving opportunities are so easy
