DfR Solutions Releases Sherlock 4.1


Reading time ( words)

DfR Solutions, leader in quality, reliability, and durability (QRD) solutions for the electronics industry, has 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."

"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.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

06/17/2022 | Andy Shaughnessy, Design007 Magazine
We’re still not officially into summer yet, but Atlanta is bringing the heat, baby! It’s hit 97 degrees a few times this week, and I now have a fan aimed right at my face. At least it’s nice and humid too. I’m glad I don’t wear make-up. And it’s been a hot week in the circuit board community. This week, Eltek reported a fire at a board shop in Israel, and Flex committed to building a 145,000-square-foor facility in Jalisco, Mexico to serve the electric and autonomous vehicle segment.

Additive Design: Same Steps, Different Order

04/12/2022 | I-Connect007 Editorial Team
We recently spoke with Dave Torp, CEO of Winonics, about the company’s additive and semi-additive processes and what PCB designers need to know if they’re considering designing boards with these new technologies. As Dave explains, additive design is not much different from traditional design, but the steps in the design cycle are out of order, and additive designers must communicate with their fabricators because so much of the new processes are still proprietary.

AltiumLive 2022: Left-Shifting Modeling and Simulation

03/10/2022 | Andy Shaughnessy, I-Connect007
Harry Kennedy and Sarmad Khemmoro of Altair recently spoke with Andy Shaughnessy about their AltiumLive presentations, which are now available online. They discuss the need for modeling, simulation, and verification in PCB design, and why these actions should be performed as early in the design process as possible.
