Top 5 reasons for solder joint failure

Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect solder joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes of solder joint failure during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

Onshape includes PennEngineering PEM hardware

Onshape, a next-gen cloud CAD and data management platform that speeds up product development, has partnered with PennEngineering, a global leader in the fastening industry, to include PEM hardware as a built-in standard for its 3D CAD models. Onshape will initially include PEM brand self-clinching nuts and self-clinching standoffs, and plans to add additional PennEngineering products to its Standard Content library in the future. PEM fasteners are typically used when a component must be readily replaced and where loose nuts and hardware aren't accessible during the final assembly process. By embedding a threaded nut into a piece of metal mechanically, it saves time and reduces post-manufacturing assembly processes. This efficiency is especially important when producing large quantities of parts.

3D inverse design helps military OEM develop unique cooling fans

A U.S.-based defense contractor, an original equipment manufacturer (OEM) of life support systems (LSS) for military applications, had a need for a custom fan to be integrated in its product line. With TURBOdesign1 from Advanced Design Technology (ADT), the company was able to bring the fan design process in-house and cut design time as well as production cost.

In developing the fan, engineers were challenged to develop a large air-flow-volume, low-pressure fan characteristic with high air velocities over the stator blades. In order to achieve the best aerodynamic efficiency, it was required to avoid separation at the stator while recovering the static pressure. No existing standard design was known that could satisfy the requirements to efficiency, size, and operating speed.

Reducing the fan noise was an additional design objective. Certain rotor design features were desirable to minimize fan noise: forward sweep of the rotor blades, plus reduced chord length at the shroud were to eliminate the possibility of vortices shedding off from the suction side of the rotor blades and hitting the next blade pressure side close to the trailing edge. Another desirable feature was positive blade stacking at the rotor blade tip to minimize losses and noise associated with the tip clearance.

Originally, the company evaluated several conventional fan design approaches, including all the available commercial codes for design of turbomachinery based on a direct design approach. The evaluation criteria included computer system requirements and associated hardware costs, the number of engineers needed to be involved in the design process, and the learning curve to produce new designs with a high level of confidence. ADT's TURBOdesign1 software came out the winner, in part because it did not require special hardware and, after just three weeks of initial training, engineers were able to tackle their first fan design case.

The design team used ADT's TURBOdesign1 3D inverse design code to introduce these new features and achieve rotor blade loading that produces the required flow and pressure rise at the lowest shaft power with a sufficient stall margin.

After completing and testing two different axial fan designs, the company engineers became more confident that their next designs would be successful. Examples of the resulting geometries of the stage are shown in Figures 1 and 2.

ADT's TURBOdesign1 inverse design code, used together with CD Adapco Star CCM+ computational fluid dynamics (CFD) software, has proven to satisfy all of the new design objectives.

"We found ourselves using all the features implemented in the TURBOdesign1 code," said the company's aerodynamics engineer. "In addition to specifying meridional geometry and blade loading, having the ability to specify custom blade thickness, stacking location, and stacking profiles was very useful in achieving good aerodynamic designs."

TURBOdesign1 output data was exported to a spreadsheet, and additional design parameters, like diffusion factor for axial fans, were evaluated during the design procedure. This gave the designers an even higher level of confidence early in the design process, before taking it to CFD for evaluation and prototype construction and testing.

The use of ADT's TURBOdesign1 software made it possible to design an entirely new cooling fan from scratch, starting only from design requirements. In the process, the company was able to eliminate the costs of using outside consultants, reduce the lead time for new turbo-machinery designs of this type, and produce its own designs in-house that are best suited to its application needs.

"We cannot put a dollar figure on our new ability to design our own fans," said one design engineer. "But, in our opinion, it's invaluable."
