Topic of discussion:
Today’s electronic component packaging technologies of smaller packages (0201/01005/008003), finer lead pitch (0.4/0.35/0.3/…), bottom terminated components (QFN/LGA) and printed circuit board designs (high layer counts, finer lines, via in pad (VIP), increased copper thicknesses, copper routing, …), increased thermal sensitivity, trailing component, fabrication and assembly industry standards have impacted traditional assembly processes with addition of tight solder application, component placement, thermal management and soldering constraints. Using traditional, simplified mass production techniques are not be sufficient to achieve a high-yielding manufacturing process. This presentation will highlight elements of the impacts of these technologies on reliability and yield when not properly addressed in the design/assembly/inspection-test process, impacts of thermal connections on through-hole and surface soldering processes, introduce the elements of design for matched process (DFMP), and provide examples of several opportunities within the DFMP for yield improvement through manufacturing tooling design, SMT and PTH assembly process matching. The concept of manufacturing, test, reliability by design (XBD) will be presented.
What you will learn:
• Component packaging impacts
• PCB design impacts and industry standards limitations
• SMT and PTH solder design impacts
• Components with thermal management impacts:
- Component design
- PCB Thermal balance: X, Y and Z axis
- Trace routing
- Equipment limitation/tolerance
- PCB array tolerance
- Process tooling design
• Paste volume, thermal shock SMT and PTH, reflow process warpage

Speaker: Paul T. Vianco, Sandia National Laboratories
The development of advanced electronic packaging technologies – die materials, molding compounds, printed circuit board substrate, solder alloys etc. – is rapidly outpacing the capacity for empirical testing to provide adequate reliability data towards the design, manufacture, and fielding of components, printed wiring assemblies (PWAs), and next level sub-assemblies. Moreover, the increased reliance on electronics across different product lines has required reliability analyses to address a wider range of accelerated aging tests and service environments. Sandia recognized the challenges of this scenario and, as such, placed an emphasis on the development of computational models to predict the long-term reliability of advanced electronic packaging technologies. Although the expressed focus of these development efforts has been on solder joint reliability, the underlying toolset has been applied to such topics as die cracking, molding compound delamination, as well as the survivability of PWAs when exposed to shock and vibration conditions.
This presentation will describe the development of the computational modeling tools currently being used to support design decision for advanced, high-reliability electronics. The model predictions have been used to introduce bottom terminated components (BTCs) as well as stacked package components in such hardware. The numerical approach has been instrumental for documenting the long-term performance of alternative solder interconnections. An offshoot of this effort, which is currently being explored at Sandia, has been to predict the effects of Au embrittlement and Pb-contamination on solder joint performance and reliability. Several case studies will be presented to illustrate the predictions provided by computational modeling capability and its role in multiple applications.

Electronics in Harsh Environments Conference +
Crowne Plaza Amsterdam - Schiphol
Amsterdam 2132 HZ Netherlands
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. 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. Contact Tanya Martin, firstname.lastname@example.org, with questions or comments.

Novel Approach to Void Reduction Using Microflux Coated Solder Preforms for QFN/BTC Packages that Generate Heat
Speaker: Jason Fullerton, Alpha Assembly Solutions
The requirement to reconsider traditional soldering methods is becoming more relevant as the demand for bottom terminated components (QFN/BTC) increases. Thermal pads under said components are designed to enhance the thermal and electrical performance of the component and ultimately allow the component to run more efficiently. Additionally, low voiding is important in decreasing the current path of the circuit to maximize high speed and RF performances. The demand to develop smaller, more reliable, packages has seen voiding requirements decrease below 15 percent and in some instances, below 10 percent.
Earlier work has demonstrated the use of micro-fluxed solder preforms as a mechanism to reduce voiding. The current work builds upon these results to focus on developing an engineered approach to void reduction in leadless components (QFN) through increasing understanding of how processing parameters and a use of custom designed micro-fluxed preforms interact. Leveraging the use of a micro-fluxed solder preform in conjunction with low voiding solder paste, stencil design, and application knowhow are critical factors in determining voiding in QFN packages. The study presented seeks to understand the vectors that can contribute to voiding such as PCB pad finish, reflow profile, reflow atmosphere, via configuration, and ultimately solder design.
A collaboration between three companies consisting of solder materials supplier, a power semiconductor supplier, and an electronic assembly manufacturer worked together for an in-depth study into the effectiveness of solder preforms at reducing voiding under some of the most prevalent bottom terminated components packages. The effects of factors such as thermal pad size, finish on PCB, preform types, stencil design, reflow profile and atmosphere, have been evaluated using lead-free SAC305 low voiding solder paste and micro-fluxed preforms. Design and manufacturing rules developed from this work will be discussed.
9:30am - 10:00am
Identifying Defects on BTC Assemblies with X-ray Analysis
Speaker: Bill Cardoso, Ph.D., Creative Electron
The use of x-ray inspection in the electronics industry has gained wide adoption in the past 20 years, driven mainly by the development and use of bottom terminated components (BTC). The use of ball grid arrays (BGA), for example, allowed the development of standards and guidelines that dictate the maximum void size in each ball. In consequence, x-ray machine manufacturers developed solutions that address these requirements to became an integral part of the quality assurance function of modern electronic manufacturers.
However, as new x-ray technologies are introduced – from new algorithms to new hardware – users are faced with a growing range of options to choose from. Users need a solid technical background to understand these options to make an educated decision when acquiring x-ray inspection capabilities. For example, what level of resolution is necessary for a specific application? Is an open tube or sealed source the most appropriate technology to deploy?
The goal of this presentation is to give the audience the tools needed to avoid making mistakes when acquiring x-ray inspection capabilities. Instead of focusing on the x-ray technology per se, this work starts from the application needs of the electronic industry and ties it back to the available technology offerings available in the market today. The goal is to set the record straight and clearly define critical concepts in x-ray inspection. The different x-ray modalities, 2D, 2.5D, and 3D x-ray inspection will be explained in details at the user level – no math involved. Most importantly, this presentation will cover when each modality must be utilized for a successful quality assurance program. A rich set of images and videos will be used to illustrate the advantages and disadvantages of each x-ray inspection modality.
11:00am - 12:00pm
Expert Panel Discussion on BTC Challenges and Strategies
Hosts: Martin Anselm, RIT, and Kim Flanagan, Indium Corporation

Avoiding the Pitfalls of BTC Assembly
Speaker: Kim Flanagan, Indium Corporation
Bottom termination component use has increased very quickly throughout the last decade. Typical assemblies now have many of these components, often varying types of BTCs on one assembly. What is there to do when one or more starts to show increased variation within the same process? Many investigations have been conducted to find materials that offer the lowest voiding in large ground plane solder joints. In addition, there are many process modifications that have been proposed over the last decade to alleviate voiding in BTC components. These include but are not limited to: pad design, pad patterning, stencil design, via positioning, solid solder addition, and reflow profile optimization.
Furthermore, improved pad design strategies have been proven in the industry. IPC committees are updating the recommendations for design and implementation of BTCs including big changes to the IPC-7093. This presentation will discuss these changes and how these strategies can be used to minimize voiding and ensure robust BTC assemblies.
2:30pm - 3:00pm
Reflow Solutions to Minimize Voiding
Speaker: Dave Heller, Heller Industires Inc.
Vacuum assisted reflow soldering is a robust process that reduces void % in SMT and die attach soldering, typically by a factor of 10X. Thermal cycling test results have indicated that solder joint fatigue life and die life in BGAs, bottom terminated components, LEDs and power devices can be reduced by excessive solder joint voids. Much work has been done in the past to optimize flux, pad, component metallization, and solder paste deposition but these changes have not reduced voids in a thorough and consistent manner. This paper will review customer and lab experience in reducing voids in typical die attach and SMT applications as well as review the equipment needed for vacuum assisted reflow. These results can be applied to existing soldering processes that may currently produce excess voids and inadequate reliability.
