If you want to see inside an integrated circuit (IC), you generally have to take the die out of the package, which can be technically challenging and often destroys the …read more Continue reading [Bunnie] Peeks Inside ICs with IR
Decapsulating ICs used to be an exotic technique. (I should know, I did that professionally for one of the big IC vendors back in the 1980s.) These days, more and more people are learning to take apart ICs for a variety of reasons. If you are interested in doing it …read more
We always look forward to a new blog post by [Ken Shirriff] and this latest one didn’t cure us of that. His topic this time? Comparing two Game Boy audio chips. People have noticed before that the Game Boy Color sounds very different than a classic Game Boy, and he …read more

We see quite a bit of work where people decapsulate ICs or other solid state devices to expose their inner workings. But how about hollow state? [Tomtektest] had a dual triode that has lost its vacuum integrity — gone to air, as he calls it — and decided to open …read more
ICs have certainly changed electronics, but how much do you really know about how they are built on the inside? While decapsulating and studying a modern CPU with 14 nanometer geometry is probably not a great first project, a simple 54HC00 logic gate is much larger and much easier to analyze, even at low magnification. [Robert Baruch] took a die image of the chip and worked out what was going on, and shares his analysis in a recent video. You can see that video, below.
The CMOS structures are simple because a MOSFET is so simple to make on an …read more
A few years ago, writing for a blog called Motherboard of all things, [Emanuel Maiberg] wrote PC Gaming Is Still Way Too Hard. The premise is that custom building a gaming PC is too hard, because you have to source components and comparison shop. Again, this was written for Motherboard. Personally, I would have shopped that story around a bit more. Now, the same author is back again, telling us PC Building Simulator is way more fun than building a real computer. It’s my early nomination for worst tech article of the year.
Speaking of motherboards, This is a …read more

Have you ever wondered how you could look at a chip and map out its schematic? [Robert Baruch] wants to show you how he does it and he does in a new video (see below). The video assumes you know how to expose the die because he’s made a video about that before.
This video focuses on using his Beaglebone-driven microscope stage to get high-resolution micrographs stitched together from smaller shots. A 3D-printed sample holder keeps the part from moving around. Luckily, there’s software to stitch the images together. Once he has the die photo, he will etch away the …read more
If you’ve ever wanted to open up an IC to see what’s inside it, you have a few options. The ceramic packages with a metal lid will succumb to a hobby knife. That’s easy. The common epoxy packages are harder, and usually require a mix of mechanical milling and the use of an acid (like fuming nitric, for example). [Robert Baruch] wanted to open a fully ceramic package so he used the “cooler” part of a MAP gas torch. If you like seeing things get hot in an open flame, you might enjoy the video below.
Spoiler alert: [Robert] found …read more
Integrated circuits are a fundamental part of almost all modern electronics, yet they closely resemble the proverbial “black box” – we may understand the inputs and outputs, but how many of us truly understand what goes on inside? Over the years, the process of decapping ICs has become popular – the removal of the package to enable peeping eyes to glimpse the mysteries inside. It’s an art that requires mastery of chemistry, microscopy and photography on top of the usual physics skills needed to understand electronics. Done properly, it allows an astute mind to reverse engineer the workings of the …read more
