    SMTA Webinar:
    PCB Surface Finishing Overview: How Process Parameters Effect Functional Performance
    Wednesday, April 20, 2016
    1:00pm to 2:30pm Eastern
    Presented by: Leonara Toscano, MacDermid Enthone

    The performance expectations of printed circuit board surface finishes are greater than just solderability preservation. Historically, they were designed solely to protect copper from oxidation prior to the soldering of components. This included any storage and transportation from board manufacture to the assembly facility. Now the expectations are much greater; superior solderability, contact performance, wire bondability, corrosion resistance, extended life in aggressive environments and all this must be achieved at a low cost.

    As the last step in the manufacture of printed circuit boards, all process steps leading to the surface finish must be taken into consideration. The quality of the product entering the surface finish line will affect the resultant performance. It is important to follow operating guidelines to ensure a wide operating window. This Tutorial will detail the surface finishes on the market and the pros and cons associated with them from a fabrication perspective. It will review process cycles and suggest areas from improvement. The session will focus on process parameters within the surface finish line to help promote a wide operating window and achieve desired performance.

    This will not only benefit the line engineer but also supplier quality managers and the designers putting various finishes into their specifications. It will also give end users a better understanding of the challenges associated with each surface finish which may help with selection for specific technologies.

    1. Review of surface finish offerings
    2. Surface finish process cycles and suggestions for improved performance
    3. Discussion of the copper quality entering the surface finish line and its effects

    Who Should Attend: Anyone who deals with specifications and/or defect analysis for surface finishes. Those responsible for choosing the surface finish for end use products. Process engineers and supplier quality managers.

    SMTA Webtorial:
    It is Time for Low Temperature - Low Temperature Solders, New Development, and Their Applications
    Two (2) 90 minute Sessions
    Tuesday, May 17 and Thursday, May 19, 2016

    1:00-2:30pm Eastern
    Presented by: Ning-Cheng Lee, Ph.D., Indium Corporation

    Since the dawn of the electronic industry, the soldering process encompasses mainly component manufacturing and printed circuit board assembly with hierarchic melting range selection. The former use solder alloys with melting temperatures around 300C, which will not melt in the subsequent PCB assembly process, where the solders typically melt around 200C. Low temperature solders with melting temperature < 180C are currently mainly used for niche applications. However, the iNEMI Roadmap predicts low temperature soldering to become one of the main stream processes by 2017. Low temperature soldering is greatly desired for a number of special applications, such as heat sensitive devices, systems with more hierarchic levels, parts with significant difference in coefficient of thermal expansion, components exhibiting severe thermal warpage, or products with highly miniaturized design. This course will cover the varieties of low temperature solders with emphasis on lead-free alloys, their physical, mechanical, and soldering properties, and the applications involved with those alloys.


  • Market Demand & Tentative Binary Alloys Options
  • SnIn
  • BiSn
  • BiSn + Ag
  • BiSn + Proprietary Dopants
  • BiSn + In, Ni
  • BiSn + Sb, Zn, Ag
  • SnInAg & Applications
  • Summary
  • Appendix

    What you will Learn
    You will learn the benefits of low temperature soldering, and how this may broaden your options in product design, your soldering process, your choice of components and board materials, and hierarchic combinations. You will also know the variety of solder alloys, and the pro and cons of each of the alloys in terms of their properties and their performance at the applications.

    Who Should Attend:
    Technology directors, technology managers, product managers, design engineers, process engineers, reliability engineers, material scientists, process technicians, and any one who is interested in low temperature soldering, their applications, and wants to know how to achieve it should take this course.

    SMTA Webtorial:
    Robotic Iron and Laser Soldering for Lead-Free and High Temperature Alloys
    Two (2) 90 minute Sessions
    Tuesday, November 8 and Tuesday, November 15, 2016

    12:00pm-1:30pm Eastern
    Presented by: Bob Willis, & NPL National Physical Laboratory

    When we start to talk about high temperature electronics it's not the solder it's all the parts that make up an electronic assembly. Substrates, components, connectors, cables, solder and all of the assembly process needs to be examined in detail. Some newer techniques of soldering can reduce the stress on boards and components and also need through put requirements of modern manufacture. Working at high temperature means between 150-200oC, however, there are many applications that have to work at much higher levels, up to 300oC. Typically the industries affected by these hostile working conductions include, aerospace, automotive, petrochemical and military. The use of selective soldering is used with high temperature materials and more recently there is a growth in the use of robotic laser and iron soldering. These systems are being used telecom and automotive producers with different cored wire combinations.

    High Temp Defects

    The webinar is a mixture or theory and practical assembly trial evaluation results with current and future technology using selective soldering plus laser and robotic iron soldering processes at NPL National Physical Laboratory . A FREE copy of the High Temperature Electronics Defect Guide will be provided to each delegate. The defect charts can be printed on site for future reference or training. A guide to major reference sources and publication on high temperature manufacture will be discussed and suppliers providing different assembly resources.

    High Temp Defects

    Topics may include:

  • Oil, Gas, Space, Automotive & Military Applications
  • Reference books, specification and standards
  • Product temperature range
  • Component compatibility
