preprocessing, Sherlock automatically translates ECAD and MCAE data into 3D finite element models in minutes. In post‐processing, Sherlock automates thermal derating and democratizes the thermal and mechanical analysis of electronics.
Sherlock seamlessly integrates with already existing simulation workflows in the hardware design process. It is most valuable when implemented in the early design stages, such as:
Initial parts selection
Initial parts placement
Selecting the final bill of material
Final layout
Design for manufacturing
Sherlock makes ANSYS SIwave, ANSYS Icepak, and ANSYS Mechanical users more efficient. It directly connects simulation to material and manufacturing costs.
Additionally, Sherlock's locked IP model protects intellectual property in the supply chain. With the locked IP model, designs are transferred back and forth between design suppliers and design users while preserving PCB design details; the intended use of the PCB design will not be disclosed via environmental conditions or reliability requirements. This communication tool enables two entities to work together on a system with a layer of trust built into the reliability calculations. Sherlock simplifies and improves reliability prediction using a unique, three‐phase process consisting of data input, analysis, and reporting and recommendations.
Assessment options include:
Thermal cycling
Solder joint fatigue
PTH fatigue
Mechanical shock
Natural frequency
Harmonic vibration
Random vibration
Bending
Integrated circuit/semiconductor wear‐out
Thermal derating
Failure rate analysis
Conductive anodic filament (CAF) qualification
High‐fidelity PCB modeling
Sherlock provides actionable recommendations and presents results in comprehensive, professional reports suitable for internal and external distribution.
2.7 Summary
Establishing a comprehensive reliability program requires extensive planning, training, and expertise. Once established, however, an effective program reduces risk, costs, and failures and results in products that function reliably and satisfy customers. The simple truth is that designing in reliability up front pays off immensely over the life of the product. A reliability program ensures that this happens.
As can be seen, each type of test plan has unique properties and approaches.
