IPC Webinar to address soldering and assembly defects.

Press Release Summary:

December 2, 2010 - IPC and U.K. National Physical Laboratory have teamed up to sponsor free webinar on Jan 27, 2011. During webinar, Bob Willis, NPL process defects database consultant, will share common problems, solutions, and ways to investigate root cause of defects. Webinar will cover most frequent defect types; how to monitor process defect levels, record defects for investigation, and coordinate process parameters; and most common wave, selective, and reflow soldering defects.

FREE Soldering and Assembly Defects - Causes and Cures Webinar

Press release date: November 30, 2010

Event sponsored by the NPL Process Defects Clinic at IPC APEX EXPO(TM) BANNOCKBURN, Ill., USA, - With hundreds of opportunities for problems to surface during the electronics manufacturing process, it is a credit to the manufacturing and engineering talent of the industry that planes fly, pacemakers keep hearts beating and phones are at the ready to provide Facebook updates or even make a call. To keep these dedicated professionals up-to-date on the latest causes and cures for assembly and solder defects, IPC and the U.K. National Physical Laboratory (NPL) have teamed up to sponsor a free webinar at 12:00 pm (noon) U.S. Central time on January 27, 2011 - a precursor to the hands-on, three-day Process Defects Clinic that will be held at IPC APEX EXPO in April. According to Bob Willis, NPL process defects database consultant, the advent of lead-free technology made every step of the assembly process more difficult. "Common process problems today relate to the correct selection of printed board materials, surface finishes and soldering materials," says Willis. "While some defects are cosmetic, others have significant reliability implications. Companies incur a great deal of cost if they can't distinguish between the different types." Willis estimates that 30 percent of printed board defects relate to surface finishes and 38 percent of component problems are related to ball grid arrays. Queries about BGAs top the searches in the NPL database. During the webinar, Willis will share common problems, helpful solutions and ways to investigate the root causes. The webinar will cover the most frequent defect types; how to monitor process defect levels, record defects for investigation, and coordinate process parameters; the most common wave, selective and reflow soldering defects; and how to find defect causes and cures. Participants can e-mail their problems and photos in advance of the webinar for discussion and resolution to To sign up for the free webinar, visit To calculate the time in your area, visit and use United States/Illinois time at 12:00 pm for comparison. In April, Willis will staff a free process defects clinic at IPC APEX EXPO, taking place at the Mandalay Bay Resort & Convention Center in Las Vegas. Over three days, April 12-14, 2011, the clinic in booth 217 will help identify process problems for visitors and provide suggested solutions. Attendees of the event are invited to bring electronic assemblies for examination or process problems for discussion.
