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.


Dr. Mark Currie, Henkel    

Mark works at Henkel Corporation, and is based in Irvine California as Global Business Director for Solder, and is responsible for their technical development direction across all focus market electronic assembly sectors - dealing with Global OEM’s, Tier 1 and EMS accounts.

Mark draws from his experience of having visited over 1000 customers, lived in 7 different countries, presented at many established international conferences since 1993, and authored over 100 papers. Mark graduated with both a Manufacturing Engineering degree and PhD from the University of Salford, UK. His undergraduate final year project introduced him to solder, which enticed him to follow with ESPRC industry funded Phd on the same subject matter. As such, Mark has been familiar with solder for 28years. In that period, Mark joined Multicore (soon thereafter to be Henkel) and has gone from Academia, to a Research Scientist, to a Process Engineer, and then onto Global Technical, Marketing, Product and Business development positions with Henkel.

Webinar: Solder Paste Evaluation & Simple Tricks of the Trade  +

Organized by SMTA Europe

Bob WillisMonday 13th January @ 2:30pm - 4:00pm GMT (9:30am - 11:00am US Eastern Time)

Presenter: Bob Willis, SMTA Europe


Solder paste quality and performance is significantly important and considerable engineering goes into its production. Selecting the best materials for your product and assembly process is key to high yield and your customers' satisfaction. Solder paste must be compatible with your equipment and other processes you use like cleaning, coating and electrical test. Working with suppliers to achieve the best performance is vital but so is periodic review of materials used.

There are always improvements being made to printing and jetting technology and it is important that engineers consider whether there are technical or commercial reasons to change. We look at common testing methods and some of the simple shop floor techniques used over the years to understand the different types of process failures.


Topics include:

  • Solder paste type
  • Low & high temperature alloys
  • Solder beading
  • Solder slump
  • Reflow spitting
  • Flux condensation
  • Printing trials & test boards
  • Common paste & print failures

After the webinar there is a Q&A session which provides ample time for all delegate questions to be answered. However, if a delegate has a process example they would like cover in the webinar it will need to be provided in advance of the session.

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

Oregon Chapter: SMTA OR Chapter, January Technical Meeting, Preparing Soldering Materials for the 5G Environment  +

Axiom Electronics, LLC

Topic: Preparing Soldering Materials for the 5G Environment
Presenter: Ning-Cheng Lee
Date: Jan 21st, 2020
Time: 4:00-7:00PM
Place: Axiom Electronics [9845 NE Eckert Drive Suite 200, Hillsboro, OR 97006]
Abstract: 5G is coming, driven by the market need and anticipation. Coming with 5G need also comes the need to upgrade assembly materials to cope with the dramatic increase in the speed of electronic signals as well as the demand for reliability. In this talk, the desired features and directions for soldering materials will be presented, including both flux features and solder alloy requirements.
