Alpha to Highlight Low-Temp and Void Reduction Solutions at SMTAI 2017

Reading time ( words)

Alpha Assembly Solutions will be featuring its latest low temperature and void reduction assembly process technology solutions and giving multiple presentations during the SMTA International 2017 Conference and Exhibition, to be held September 17–21, 2017 at the Donald E. Stephens Covention Center in Rosemont, Illinois. Alpha will be at Booth 1016.

New products to be highlighted at the show include a new generation low temperature solder paste, ALPHA OM-550 and the innovative void reduction ALPHA AccuFlux Technology for solder preforms.

"OM-550 provides another low temperature solution to customers looking for SAC305-type mechanical and thermal reliability in a low temperature alloy," says Robert Wallace, regional marketing manager for the Americas. "We feel this paste provides customers with efficiencies in both energy and cost while improving BGA mechanical reliability compared to other low temp alloys."

Both products will be included in the New Product Showcase and will also be a focus in several of the technical papers being presented.

"Alpha has developed an innovative void reduction technology," says Jerry Sidone, product manager for engineered materials at Alpha Assembly Solutions. "The latest AccuFlux Technology for preforms has been specially designed to dramatically decrease voiding under bottom termination components, an issue of increasing importance as power densities continue to rise and managing thermal reliability becomes more of a challenge.  Our paper, Void Reduction Strategy for Bottom Termination Components (BTC) Using Special Flux Coated Preforms, will present the results of a comprehensive study that Alpha and our partners recently conducted to examine the impact of Alpha’s AccuFlux Preform Technology  on voiding under QFNs, QFPs and DPAK packages."

In total, Alpha will be presenting eight papers during the four day event, two of which will focus on low temperature technology and three addressing void reduction:

  • Void Reduction Strategy for Bottom Termination Components (BTC) Using Special Flux Coated Preforms
  • Novel Mid-Temperature Alloy for Enabling Solder Processing Temperature Heirarchy in SMT Assembly
  • High Performance Electronic Interconnect Materials Characterization – Techniques & Challenges
  • Low Temperature Soldering Using Sn-Bi Alloys
  • A Comparison of Localized Electronics Cleanliness Testing and Surface Insulation


  • Effect of Voids on Thermo-Mechanical Reliability of Solder Joints
  • Process, Design, and Material Factors for Voiding Control for Thermally Demanding Applications
  • Low-Temperature Solder Paste Process Advantages.

Under the Hood: Solder Joint Reliability

05/21/2018 | Burton Carpenter, NXP Semiconductors Inc.
It has been long established that packages using NSMD BGA pads were more resilient than ones with SMD pads to fatigue-induced solder joint cracks. However, NSMD pads in previous investigations on 292MAPBGA and 416PBGA packages failed sooner in AATS testing due to an alternate failure mode: substrate Cu trace cracks. This article looks into the effects of substrate material and package pad design on solder joint reliability of 0.8 mm pitch BGA.
