As the industry has evolved and SMT has become more demanding, it is important to understand the basics of the process. One of the most important first steps in the SMT process is successfully getting the paste on the board, which is commonly done by stencil printing. However, a majority of defects in the SMT process can stem from incorrect stencil printing setup. Going back to the basics and ensuring you have the correct setup can save you from defects down the line. In two sessions of Stencil Printing 101, Presenter Meagan Sloan, CSMTPE, will talk about the solder paste printing process and typical design of experiments (DOE) that can be used to obtain data on how the solder paste will perform.

More

Soldering defects in SMT can arise from three main areas: the design, the materials, and the process. Identifying the root cause and troubleshooting these defects can be timely and expensive. There can be many ways to resolve one solder issue and oftentimes the easiest and least expensive way to resolve one of these soldering defects is by adjusting the reflow process. But in order to understand how to best optimize the reflow profile, it is crucial to understand the basics behind the solder materials. In the two sessions of Reflow 101 from a Solder Manufacturer’s Perspective, Indium Corporation, will explain some of the materials science basics behind solder pastes and how this knowledge can be used to optimize the reflow profile in order to resolve some common solder defects.

Miniaturization has been, and continues to be, a challenge for the electronics industry. Assemblies are getting more complex and component spacing is steadily decreasing. With more dies and components packed into smaller footprints, the need for heterogeneous integration for advanced packaging is getting greater. However, solder paste printing is not always possible in some packaging designs and solder paste dispensing can be an alternative method for solder paste deposition. Ultrafine solder paste dispensing is only achievable with the correct combination of dispensing equipment and solder materials. In Ultrafine Solder Paste Dispensing for Heterogeneous Integration, presenter Kenneth Thum will discuss different dispensing equipment technologies and important solder paste characteristics, along with sharing a solution for and steps on how to achieve consistent fine-dot dispensing.

When the world was moving toward green manufacturing, lead-free soldering – originally driven by RoHS (Restriction on the use of Hazardous Substances in electrical and electronic equipment) of Europe – was becoming the mainstream for the electronics industry, and Sn-rich alloys – including SnAgCu, SnAg, and SnCu – have been prevailing for more than a decade. While the electronics industry keeps advancing rapidly toward miniaturization, two important drivers are dictating the evolution of lead-free solders: low cost and high reliability. In “The Evolution of Lead-Free Solder Alloys,” Presenter Hongwen Zhang will discuss the evolution of lead-free solders after the implementation of lead-free soldering in the industry from 2006, covering: (1) the first generation of high-Ag SAC solders; (2) low Ag/zero Ag Sn-rich solders; (3) high-reliability SAC solders; (4) low-temperature lead-free solders; and (5) high-temperature lead-free bonding materials. Zhang will also discuss the market need, and the pros and cons of the representative materials in each group.

Implementing high-density assembly in all electronic products requires a lot of considerations. Before starting any development work or implementing a new technology, it is critical to understand the product and industry requirements and capabilities; if this is not fully understood, failure is the most probable outcome.

There are many ways to increase the packaging density. However, the use of new technologies poses a number of challenges for solder paste selection, PCB design, assembly process and reliability, and the type end-product will have different challenges, concerns, and requirements in all aspects. The assembly line for many of these end-products will look very similar, but specification limits would be different. And when it comes to material section – and solder paste in particular – the type of end-product plays a big role.

Even with the right solder paste selection, a good assembly process and a quality PCB can still result in component failure, leading to yield losses and extra cost. In this webinar, we will discuss selection of the correct solder paste based on end-product and the need for doing proper root cause analysis before making any material or processes changes.

Heating PCBs for soldering can cause the substrate and components to potentially warp. This can cause parts to expand and contract, leading to common soldering defects such as HiP/HoP and non-wet opens. High-temperature lead-free soldering made these problems worse. To help solve these issues, interest had grown for low-temperature solders for reflow and selective soldering. However, not all companies have the ability to change the alloys they use. Invited guest speaker, Bob Willis will provide practical insights for common and not so common soldering and assembly problems relating to warpage. Some of the solutions as well as “shop floor tricks” will also be illustrated.

The reliability specifications for the product lifetime validation of electronic assemblies are increasing due to the changing requirements of duration of use (increased cycles) as well as increased service temperatures (125-200°C). This is especially true in high-reliability verticals such as automotive, RF, and industrial applications. This makes the choice of solder materials more critical, as the solder paste attributes have a direct impact on increased product service life reliability requirements. in "Solder Attributes & Impact on Increased Product Reliability Requirements of Electronic Assemblies," Andreas Karch will discuss the parameters that should be taken into consideration to calculate the service life using the Coffin-Manson model. He will also discuss innovative solder solutions to address the higher thermo-mechanical loads on solder joints due to the increased mission profiles and product lifetime validation requirements.
