Beltsville, MD – August 5, 2015 – DfR Solutions, a leader in quality, reliability, and durability (QRD) solutions for the electronics industry, today announced the release of the newest version of Sherlock Automated Design Analysis™ software, version 4.1.  This version of Sherlock now translates Shock Response Spectrum (SRS) Analysis into Power Spectral Density (PSD) Curves. The real value to users is the ability to predict random vibration events of electronic hardware more precisely than any tool currently available on the market. Additional enhancements in this version of Sherlock include an updated package manager, improved analysis capabilities, and a modified user interface.

Developed over 80 years ago, shock response spectrum (SRS) is used as an approximation of shock loads (explosion, seismic, launch, landings, etc.) early in the product development process. While SRS has now become the default technique for evaluating large structures in severe environments (like rockets, tanks, and airplanes), it is inadequate in capturing the risk of electronics within these same applications. Sherlock version 4.1automatically converts SRS into much more relevant Power Spectral Density (PSD) Curves. Through an understanding of the likely range of nodal responses, Sherlock allows users to incorporate SRS into the already powerful simulation and modeling capabilities within Sherlock.  Failure risks can be more accurately predicted and Sherlock users can now introduce potential mitigations at the board, box or system level much earlier in the new product development process.

Additionally, the updated Package Manager now allows for users to create new packages or copy existing packages. Previous versions of the package manager only allowed for properties of existing packages to be modified.  Other updates include improved part validation analysis, life prediction charts, and thermal event analysis.

“Repeated shock is a major concern in many high-risk environments like aerospace, avionics and defense,” stated DfR Solutions CEO Craig Hillman.  “Electronics in these conditions are subject to extreme levels of shock, unlike any other industry. Traditionally, SRS calculations have flowed down from very large structures (such as the rocket tube) to perform to assess this risk,” said Hillman.  ‘But those SRS calculations are a gross approximation and do not take into account the specific mechanical response of the electronics to shock.  This enhancement to Sherlock incorporates our deep knowledge of electronics and provides the designer, manufacturer, and system-integrator with the tools to gain deeper visibility into their risk of failure under real world conditions,” said Hillman.
