Webinar: Practical Failure Analysis Methods in Printed Board Assembly  +


Bob WillisMonday 14th October @ 2:30pm - 4:00pm UK Time (9:30am - 11:00am US Eastern Time)

Presenter: Bob Willis, SMTA Europe

Overview

Different levels of failure analysis exist, from the very basic with virtually no equipment, to the use of a full failure analysis laboratory. Often simple analysis methods can point engineers in the right direction, but proving the root cause of failure often needs the electronic pathologist with all his investigation tools. When conducting any failure analysis, it is important the results prove the cause of the fault. The true reason for failure needs to be clear and proven with hard facts, not just opinions.

 

Topics include:

  • Optical and X-ray inspection
  • Solder joint crack detection
  • Microsectioning
  • Component opening techniques
  • Surface analysis
  • Shear testing
  • Question and answer session

In preparation for the event and to ensure you are equipped to get maximum benefit from the event, read our Webinar Guide.

The webinar will run for between 60-90min with question and answer session. The webinars are limited to 100 delegates/companies. A copy of the slides will be provided after the webinar.

Oregon Chapter: SMTA Oregon Chapter: October Technical Meeting. Evaluation for 3D Printed Resins: Applications in Engineering and Manufacturing  +

Axiom Electronics, 9845 NE Eckert Dr. Suite 200, Hillsboro, OR 97006



This study aims to characterize 3D printed Resins from an applications perspective within engineering and manufacturing. 3D printing technology has grown enormously over the past decade, and is starting to make a transition from being a prototype technology to one that can be used in everyday applications around the factory floor. With the increase in technology and expansion of materials that can be used, the range for applications has increased dramatically. The aim of this study was to help create a selection guide of materials to use, by characterizing each resulting resin with the appropriate mechanical properties. A multi factorial Design of Experiments was used in order to optimize the post processing settings, to achieve maximum desired mechanical properties (Ultimate Tensile Strength, Hardness, Impact, etc…). I end goal is to provide both engineering and manufacturing another option for fabrication, as well as having an easy selection and processing guide for materials used in the factory.

“Development of a Solder Paste Test Vehicle for Miniaturized Surface Mount Technology”
 
By Dr. Mark Currie – Henkel Corporation
Authors and acknowledgements to:
Dr. Neil Poole/Doug Dixon (Henkel Electronic Materials, Irvine, CA, USA)
Chrys Shea (Shea Engineering Services)
 
 
Consumer demand has accelerated the pace of the electronics miniaturization trend, compelling assemblers to develop robust capabilities for 01005 components and 0.3 mm pitch array packages to remain competitive.  The process of acquiring these capabilities can be complex, as they involve numerous interactive factors.  To optimize the stencil printing and reflow portions of SMT assembly given the challenging new realities, a process evaluation tool has been developed that provides a turnkey solution for solder paste performance testing.
 
The evaluation toolkit incorporates PCB design, a complete and costed bill of materials, full documentation for programming, setup and test methods, and step-by-step directions for a designed experiment.  It is the product of a cooperative effort among industry specialists that draws on their materials expertise, statistical know-how and process engineering skills, and was specifically developed to make solder paste testing as easy as possible for the PCB assembler.
 
This paper details the development of the turnkey solder paste evaluation concept from a laboratory test vehicle to the complete off-the-shelf kit.  It discusses:
 
•             Component selection to reflect the current state of the market and support a 2-3 year miniaturization roadmap
•             Sample size consideration for statistical significance
•             DFM of the PCB to manage costs
•             Design for solder paste inspection (SPI)
•             Nesting of tests to evaluate 22 paste properties in 4 hours or less
•             Stencil design considerations
•             Full database for programming entire SMT line
•             PCB support design, development and testing
 
The discussion details both user and supplier perspectives on testing methods and highlights key considerations for assemblers.  It concludes with opportunities and plans for potential future developments to expand the kit’s analytical capabilities.
 
“Lead-free Solder Paste Development for Ultra Fine-Pitch Printing and Reflow of 03015 and 0201 Metric Chip Components”
 
By Shantanu Joshi - Koki Solder America Inc.
 
 
Due to the widespread popularity in mobile devices such as wearable devices and smartphones, demand for miniaturized or micro surface mount components, such as 0201 metric chip, flip chip packages, and fine-pitch surface mount land patterns to accommodate them are increasing. Consequently, solder paste is required to be compatible with this high-density surface mount technology.
 
When printing paste for 0402 metric chip components, stencil apertures of approximately 0.2mm diameter are used whereas for 0201 metric chip components, stencil apertures of the dimension 0.1mm diameter are needed. This presents challenges for both good printability and solderability. Conventional solder paste technology seems to be lacking in coping up with these stringent requirements.
 
Precise printability and optimum solder reflow parameters were evaluated on ultra-fine pitch surface mount board pads using conventional solder paste and a newly developed solder paste to understand compatibility with 0201 and 03015 metric chip components.
 
A test vehicle was used with 0402, 03015 and 0201 metric chip components. Type 51 (10-25um) and Type 6 (5-20um) no-clean lead-free Sn3Ag0.5Cu solder pastes were evaluated with two different stencil thicknesses,50um and 80um. The area apertures ratios varied from 0.28 to 0.94. The measurements of paste volume after printing were recorded using production solder paste inspection equipment.
 
After printing reflow studies were conducted on assembled 03015R and 0201C metric chip components to understand reflow behavior. The solder paste development included flux improvement to increase stencil release rate of the solder paste through the stencil apertures for the challenging stencil area aperture ratios used. The newly engineered heat resistant flux chemistry in the solder paste helped to reduce solder graping during reflow even with the small paste deposits on the board. Continual solder paste print studies as well as print to pause studies were conducted with the developed solder paste on 0201 metric and 0.3mm pitch QFP board land pads to understand the use of the solder paste in production. The results of the work will be discussed in detail.
 
 
“The Effects of Surface Finish on Solder Paste Performance”
 
By Tony Lentz – FCT Assembly
 
The surface finishes commonly used on printed circuit boards (PCBs) have an effect on solder paste performance in the surface mount process (SMT).  Some surface finishes are non-planar like hot air solder level (HASL) which can lead to inconsistencies in solder paste printing.  Other surface finishes are difficult to wet during reflow like organic solderability preservative (OSP).  What is the overall effect of surface finish on solder paste performance?  Which solder paste is best for each surface finish?  It is the goal of this paper to answer these questions.
 
In the initial work, several different surface finishes were tested in the surface mount process including:  HASL, OSP, electroless nickel immersion gold (ENIG), immersion tin, and immersion silver.  Several different types of solder pastes were tested along with each surface finish including:  lead-free no-clean and water soluble, and leaded no-clean and water-soluble solder pastes.  Each combination of surface finish and solder paste was evaluated for print performance, wetting, solder balling, graping, and voiding.  The results of this testing were quantified and summarized.  Recommendations pairing the optimal solder paste with each surface finish were given.    
 
Subsequent work explored some of the surface finish & solder paste combinations in more detail with an expanded set of SMT parameters.  Three surface finishes were studied including electroless nickel immersion gold (ENIG), organic solderability preservative (OSP), and immersion silver (ISilver).  Two solder pastes were used including a no clean SAC305 solder paste and a water soluble SAC305 solder paste.  Three different reflow conditions were tested including a ramp-to-spike (RTS) profile, a ramp-soak-spike (RSS) profile, and simulation of the double-sided surface mount process by reflowing two times through a RTS profile.  Print speeds were varied at 25, 50, and 100 mm/second and printed solder paste volumes were measured.  Reflow performance was measured and quantified including wetting, solder balling, and graping data.  Quad flat no lead (QFN) components were placed and voiding was measured in the solder joints of the QFN thermal pads. 
 
All of the test results, including data from the first study, are summarized, compared and contrasted.  Discussion of the strengths and weaknesses of each combination of surface finish and solder paste are given with respect to the various SMT parameters.  Recommendations are made for optimal combinations of surface finish and solder paste.

FREE Webinar: Advances in X-Ray for Demanding Applications  +

Organized by SMTA Penang Chapter

Location
Penang Malaysia


Wednesday 30th October @ 2:00pm Penang Time UTC+8
(2:00am US Eastern Time UTC-4)

Presenter: Keith Bryant, Chairman SMTA Europe

Free for all – only members will get access to slides and recorded presentation!

Overview

The taking of x-ray images goes back over 100 years, since then there have been numerous advances in x-ray tube and detector technology and these have been increasingly applied into helping with the manufacturing of electronic components and assemblies, as well as in their failure analysis. Most recently, this has been driven partly by the continued reduction in circuit board, device and feature size and the movement to using lower density materials within the structures, such as copper wire replacing gold wire as the interconnection material of choice within components.

However, due to the solar and battery advances, where heat transfer is critical and voiding is a huge problem, we are also seeing an increasing amount of high-density and thick materials which need to be imaged and worse still, low-density materials in combination with high-density ones. In order to meet these most recent challenges and those in the future, there have been a number of key improvements to the vital components within x-ray systems, which will be covered in the presentation.
 
The choice of available technologies, however, means selecting the tube/detector combination, which is optimum for electronics inspection is no longer so clear-cut. For example, one configuration may provide certain benefits that are applicable for one area of electronics inspection, whilst being less valid for others. This presentation will look at both ends of the spectrum of demanding applications, low-power applications using LED's as a subject and high-power applications showcasing IGBTs.
