AMD K5 CPU Delid: Exposing the Integrated Circuit within

In this video I open up an AMD-K5-PR166ABR CPU. With a combination of heat from a hot air station (set to 480C) and a bit of prying with a custom made-to-fit razor blade, I was able to remove the lid soldered to the ceramic body. The entire heating process took around 5 minutes, which I think is mainly due to the large chunk of metal on the top wicking all of the heat away. The AMD K5 series of microprocessors was released back in 1996. This version of the K5 didn't come around until January of 1997, however. It was made using a 0.35 um CMOS manufacturing process and has 4.3 million transistors. I found a lot of this information on cpu-world.com which also has loads of other great info on older parts like this. To say the silicon die inside is beautiful is an understatement. The way that the features are all arranged allow for the light to reflect in some amazing ways. Unfortunately, I ruined it a bit when I popped the lid off. Looking back at the footage, I think I had the air nozzle too close and it bounced off of it and landed back on the die, leaving a blob of solder behind. I'll remember to move the nozzle far away so that I don't repeat this in the future. Want to see more videos like this? Be sure to subscribe so you don't miss out!
