    admin created Tin Whiskers Webinar 2015

     

    In September of 2015, David Love (HDP User Group) had a conversation with Dr. Polina Snugovsky (Celestica). Polina had just wrapped up her work on the “Manhattan Project” - an Air Force sponsored long term study of the use of lead-free electronics in Aerospace and Military avionics.  In this study they uncovered new tin whisker failure modes related to SAC alloy solder joints. Although aware of the problems with certain flux types, he was quite startled at some of the other things reported.

     

    In this discussion, David and Polina decided to make the industry aware of these issues. The result was a Webinar, sponsored by the HDP User Group with the assistance of EIPC, IPC, SMTA, and SEMI, which was held on October 29, 2015. Over 190 people attended. The top people in tin whiskers research were on the panel. Topics covered were whisker growth mechanisms, real-life failure histories, and whisker mitigation strategies.

     

    HDP User Group is making this webinar freely available for you to download and watch. The original slides shown by the panelists are provided as free downloads as well. Please pass this along to your colleagues. It is important that the entire industry is aware of these findings.

Subsequently, many electronic products, in particular mobile base stations and core network nodes, need to handle enormous amounts of data per second. One important link in this communication chain is high speed press fit connectors that are often used to connect mother boards and back planes in core network nodes. These new high speed press fit connectors have several hundreds of thin, short and weak pins that are prone to damage. Small variations in via hole dimensions or hole plating thickness affect the connections; if the holes are too small, the pins may be bent or permanently deformed and if the holes are too large they will not form gas tight connections. An example of deformed high speed connector press fit pins inserted in plated holes of different sizes is given in Figure 1. Figure 1 – 3D CT x-ray image of deformed high speed press fit connection pins1. The goal of this project was to understand how rework of these new high speed press fit connectors affects connection strengths, hole wall deformations and plating cracks. admin created Press Fit Paper Published at APEX 2017

    [Public] admin created High Fequency Measurements Paper Published at APEX 2015 May 2, 2017 - 10:35am Abstract The High Density Packaging (HDP) user group has completed a project to evaluate the majority of viable Dk (Dielectric Constant)/Df (Dissipation Factor) electrical test methods, with a focus on the methods used for speeds above 2.0 GHz. A comparison of test methods at common through to higher frequency ranges was desired, testing a variety of laminate materials (standard volume production with UL approval, low loss, and "halogen-free" laminate materials). Variations in the test board material resin content/construction and copper foil surface roughness/type were minimized.  Problems with Dk and Df test methods and discrepancies in results are identified, as well as possible correlations or relationships among higher speed Dk & Df test methods.  An example of present difficulties with the variety of test methods used for the same laminate material: a) Cavity resonator method at 10 GHz: Df = 0.008 b) SPP Df test data at 6 GHz:   Df = 0.006 to 0.0075 c) IPC TM 2.5.5.5, 2-20 GHz Stripline, Panasonic Method    (3 layer stripline TV, 2x1078 dielectrics ~65% RC, 0.15 mm core): E-Glass Foil Type P using E-glass: Df = 0.003 to 0.006 Foil Type P using NE-Glass:  Df = 0.002 to 0.005 Foil Type R using E-Glass:  Df = 0.004 to 0.007 Foil Type R using NE-Glass:  Df = 0.003 to 0.006 d) IPC TM-650, 2.5.5.9, Laminator published data sheet [1 GHz, 54% RC]: Df = 0.002 The above shows a range of Df from 0.002 to 0.008 depending upon the test method and frequency used.  Dk measurement methods have similar disparities. admin created High Fequency Measurements Paper Published at APEX 2015
