Can SpaceClaim Provide Frustration Management? In all our years of doing analysis, we have discovered that waiting can be frustrating. Broken CAD. Dirty Geometry. Simulation Delays. Mounting Frustration. We have experienced all four. And this causes a significant breakdown in the entire development cycle. And when we consider all of the other people we

So far we have explored preliminary ways to predict the temperatures in a circuit using simple thermal resistance network calculations. This post addresses improved thermal analysis for electronics cooling. Consistent exposure to high operating temperatures can lead to degradation of material properties and development of thermal stresses that can ultimately lead to device failure. The

154,000,000,000,000 Reasons Back in July, we posted a Blog announcing Third Frontier Commission Invests in Ohio Businesses. Just recently, Douglas J. Guth in HiVelocity Magazine highlighted 154 Trillion reasons why. His article is a must read, especially for those Ohio businesses who have felt like they were part of the “missing middle.” Read the

During our recent webinar with COMSOL on thermal-structure interaction modeling, we at AltaSim Technologies demonstrated modeling of a MEMS energy harvester that scavenges waste heat. Examples of sources for waste heat range from microprocessor chips, to internal combustion engines, to chemical processing plants. If the waste heat generated from these cases could be used to

Previously we have discussed ways to complete a feasibility thermal management analysis. For a given thermal budget, we want to determine whether the junction temperature will meet specifications for reliability and thermal runaway. In electronic systems that rely on air flow for cooling, convection is of paramount importance. Power dissipation due to convection

FEA (Finite Element Analysis) – Critical Questions to Ask Jack Thornton, MINDFEED Marcomm, wrote an excellent article on FEA that we really thought would be good to share – “Questions Decision Makers Should Ask About Computer Simulations”. Thornton starts out his article with the following two paragraphs: “The computerization of engineering (and everything

In an earlier blog the thermal resistance network shown in Figure 1 was developed. Figure 1: The heat dissipation paths from the die are: to the case of the package, and through the BGA into the PCB. Heat is then dissipated through the skin of the device by convection to the environment. The two dissipation

During a feasibility analysis for electronics cooling solutions, the objective is to estimate the heat flow using engineering approaches and judgment. By applying a thermal resistance network to the heat flow pathways within the system quantitative estimates for heat flow can be developed as an initial screen for feasibility of component design. As an example
