"The Unintended Consequences of Cleaning"
This "conversation-style" presentation covers several popular cleaning-related subjects and provides answers to popular questions including:
  • Many of us haven't cleaned for more than twenty years. Why do we need to clean now?
  • How much assembly contamination is acceptable?
  • What's the true cost of cleaning?
  • How are most assemblers cleaning their assemblies?
  • Do I need a chemical to clean?
  • What's the environmental impact when I clean (am I solving one problem and creating another)?
  • Are there any alternatives to cleaning?
  • What happened when a contract manufacturer did not say "no"
  • How clean is clean enough?

10:30AM Naveen Ravindran, M.S.Ch.E.
Zestron
"Reflow, Multiple Thermal Cycles and Cleaning No Clean Solder Paste and the Impact on PCB Reliability"
Printed circuit board manufacturing is an interactive process with complex components and material sets. When designing PCBs, solder paste selection and proper cleaning is critical, even when using No Clean. As PCB surface density and component mass continuously increase, the recommended thermal profile must be sufficient to produce quality solder bonds and fully volatize flux residues. Remaining flux residues on the board, if ionic in nature, can lead to failure mechanisms. This presentation will address the importance of employing an optimized cleaning process, the effects of thermal profile variations and multiple thermal heat cycles on the PCB cleaning process. Additionally, cleanliness assessment and process control tools will be presented.

11:30AM Lunch

12:15PM Robert Wallace - Regional Marketing and Channel Partner Manager - Americas
Alpha Assembly Solutions
"Soldering Material Set Selection and the Potential Effect on High Reliability Electronics"
This seminar will highlight how Soldering Material Set Choices play an important role in the functionality and long term reliability of today’s electronics. The move to Pb Free soldering together with increasing complexity of assemblies has put increased pressure on making the right decisions when it comes to Solder Paste, Liquid Flux, and Rework Material selection and processes used in the assembly process. An understanding of Electrochemical Reliability and how to make the right Material Set Choice as well as the decision to clean or not to clean your assemblies is the focus of the seminar.

1:15PM Break

1:30PM Mike Burgess - AR ("As Required")
ASM Assembly Solutions -DEK
"Modern Day Stencils and Materials for a Robust SMT Printing Processes"
It is well understood 60 to 70 percent of all defects in electronic circuit board assembly can be traced back to the printing process. Printing machines amongst the manufacturers have evolved to provide repeatable stencil to substrate alignment, consistent print speed and squeegee pressure, although achieving consistent solder paste volume can be difficult given the mixture of components on a given assembly. Stencils are a key element of the printing process responsible for delivering a precise volume of solder paste repeatability to the desired location on the board throughout the life of the stencil. The stencil supply industry has improved over the years, with more advanced lasers, better and finer grains of stainless steel, various stencil coatings and more recently higher tensioned stencils. With these advancements, satisfying the heterogeneous challenge of solder demand for large and small component features are achievable with the right stencil designs and material specification when printing area ratios that drop below 0.66. Selection of proper understencil cleaning material sets and frequency of cleaning also plays an important role in achieving consistent printing through a given production run. The interaction of aperture design, stencil alloys, coatings, and cleaning materials to optimize printing will be discussed. Modern 3D Electroformed stencils with custom squeegee blades can transform a slow inconsistent dispensing process into a faster, more reliable and automated printing process. This opens up a wide range of printing solutions for semiconductor packaging as well as traditional circuit board requirements when needing to print on different planes. Different applications and solution will be shared.
