    Solder Joint Voids- All You Should Know

    Two (2) 90 minute Sessions
    Nov 1 and 2, 2017
    1:00pm to 2:30pm Eastern
    Jennie Hwang Presented by: Jennie S. Hwang, Ph.D., H-Technologies Group


    With the goal to produce reliable products while achieving high yield production, this webtorial provides a holistic overview on solder joint voids. Four fronts in the industry have rekindled the interest and/or concerns about solder joint voids – the lead-free solder joints; the increased use of advanced packages (BTCs, PoPs); the ever-miniaturized electronics comprising “delicate” solder joints; and the increased demand in solder joint reliability for high performance and high reliability products. Different sources of solder joint voids, their respective causes and effects on the solder joint performance and reliability will be discussed. The practiced acceptance criteria of solder joint voids vs. real-world performance, and the steps to minimize solder joint voids of both the array solder ball solder joints (e.g., PoP, BGA, CSP) and lead-frame solder joints (e.g., QFP, BTC) will be outlined. The webtorial will conclude with the source of voids that is most critical to reliability, thus to avoid.

    Course Outline:
    Part 1

  • Driving Forces and potential effects
  • Likely impact on Reliability
  • Case studies
  • Different Sources
  • Factors contributing to each of the sources
  • Role of solder alloy composition

    Part 2

  • Mitigating approaches
  • BGA voiding – additional factors
  • BTC, PoP solder joint voids
  • Inspection
  • Voids criteria vs. applications
  • Most critical source of voids to avoid
  • Summary & recommendations

    Who Should Attend:
    The webtorial provides the working knowledge to all who are concerned about the reliability or interested in understanding the solder joint properties in relation to voids including designers, engineers, researchers, managers and business decision makers; also is designed for those who desire the broad-based information.

    Jennie Hwang Presented by: Bob Willis,

    The session includes solder paste testing, different reflow methods, reliable solder joint formation on high and low temperature and causes and cures of most common failures. Here we examine the most common process issues seen in the industry and how design, board selection and process materials can cause issues in manufacture. We look at the fundamentals of reflow with convection and vapour phase to understand the cause of failures

    With over 40 years in industry and 30 solving process problems for industry Bob Willis explains the causes and curses of most reflow issues see in industry. Bob’s session features many unique process video clips on testing and failures and make his sessions come alive providing a much better understanding of the root cause of failure and corrective action. Each delegate registered on the webinar will receive a free set of wall charts on reflow soldering and temperature profiling

    If you have a specific process problems with reflow send it to Bob to include in the webinar.

    Topics will include:

  • Design for reflow soldering
  • Selecting the best solder paste
  • Fundamentals of solder joint formation
  • Optimising your reflow process
  • Correct profiling procedures
  • Correct PCB finish for your process
  • Common soldering problems and why they occur
  • Reliability of solder joints
  • Practical testing of solder joints

    SMTA Webtorial:
    X-Ray Inspection of PCBs

    Two (2) 90 minute Sessions
    December 6 and 13, 2017
    1:00pm to 2:30pm Eastern
    Presented by: Kamran Iqbal, Nikon Imagining and Bob Wetterman, BEST

    This webinar series will focus on the x-ray inspection of printed circuit boards. This seminar will be taught by two subject matter experts, one coming from the vantage point of inspection as part of being a service provider and the other from an x-ray researcher who will come at the discussion from an imaging and machine capability standpoint.

    With the ever increasing trend towards miniaturization and the use of components with non-visual inspect able criteria, x-ray as QC tool is becoming a necessity even to the Tier 1 PCBA assembly area. Devices with pads underneath the device such as QFNs, LCCCs and LGAs have become the most placed component body style. Without x-ray the inspection and quality inspection cannot be made. Couple this to other devices such as traditional BGAs and ever finer-pitch connectors and the need for x-ray imaging augmenting optical inspection is getting to be a necessity. Even older throughhole devices, with lead-free solders and large thermal masses will test the ability to create proper hole fill. Verification of this hole fill becomes increasingly necessary.

    This webinar series will have the following overarching goals:

  • Understand the most important specifications in procuring a modern x-ray machine
  • Understand how x-ray inspection is used to inspect a variety of electronic component body styles including leadless devices, area array devices, high density connectors, throughhole connections and standard SMT components
  • Understand how x-ray inspection is used for inspection, defect analysis and troubleshooting in the SMT process
  • Understand how industry standards tie in with the use of x-ray inspection

    Who Should Attend:

  • SMT assembly process engineers and technicians responsible for production or new product introduction processes
  • SMT quality personnel interested in helping improve end-of-line yields and identifying root causes of failures
  • OEM supply chain engineers responsible for supporting and/or assessing SMT assembly contractors
  • Engineers and technicians just entering the SMT field who want to master the science and art of x-ray inspection

    Kamran Iqbal Kamran Iqbal is currently a product manager with Nikon Imagining having experience with Nordson/Dage and Goepel Eectronics He also has experience in the automotive, medical and defense industries. He has extensive applications experience within the semiconductor industry, device packaging, SMT, Manufacturing, test and inspection.
