Mechanical Analysis Blog

It has been way too long since I last wrote a blog article…It is amazing to me how fast time flies between blogs.  A lot of ideas pop into my head that I think would be an interesting read but all of them still reside in my head.  One idea that has been haunting me is the topic of this blog.  Part of the problem was that I had a hard time deciding what would be the point of the blog.  Rather than wait … Read More

Heat Spreading, Electronics Cooling

Some time back we were testing a flip-chip package in a top-cold-plate harness to measure the package junction-to-case thermal resistance (ΘJC, RJC).   We performed a number of tests where we were consistently measuring a higher value of thermal resistance than was reported by the vendor.   How could we and the vendor both be correct?!? To understand this further I built an analysis model to study … Read More
