To get to the silicon in this part, I'll use hot air to weaken the black epoxy to the point where I can start to chip away at it. Once the silicon chip is removed, I'll use a #PCBcoin to move it over to the microscope for further viewing.

This chip is the IR2157 from International Rectifier and has a lot of interesting features, including some sections that are isolated from the rest of the circuits. This chip also has a Pac-man for the copyright symbol, and a ghost for the Maskworks M.
A few of the pins on this IC are rated for voltages up to 625V, which is why they require isolation.
If you want to learn more about this part, I would Highly recommend checking out the datasheet. It's well written and includes a nice block diagram of the internal components.

I'm just blown away that they were doing this in the 70s and 80s

You show the true face of electronics. In terms of quality and quantity this channel is unique. Richly detailed explanations of how electronics really work. This work helps preserve many components that may be forgotten.
I don't know why other YouTubers don't look like your channel.
Congratulations and please continue publishing more videos.

I never gave microcircuits a second thought until I came upon this channel. I don’t understand half the nomenclature but gosh darned it, you make tiny silicon chips interesting as heck.😂

...and I've never treated these components with respect - until now 😯

YESSS MORE MICROSCOPE CIRCUITS OMG MOOORE

Hard to believe a chip can isolate 625 volts at micrometer dimensions.
18 |
IR is now Infineon Technologies now I believe.

The way it's zoomed into, it feels like you are zooming in Google maps 😱😱

mind-bottling stuff! amazing how the human brain came up with these hings

You are managing to show the real face of electronics.

Love this stuff

As a newbie ewaste collector, could you add the metal scrape content? This would be incredible

Perfect, thank you for your efforts to keep curiosity alive!, can you please tell me about your microscope property and price to have some idea

This is f’ing insane

Cool 😊

I wish you had an SST chip for cars. I want to see what's in that without ruining the map for me car.

I'm so curious what's inside a arduino uno IC

Any chance you could show a 555 or a simple opamp like a 741 or TL 071... data books show a diagram so be great to see if the internals are recognisable.

Worked at a Philips Semiconductors (now NXP) in the early 2000's at the department where they designed this kind of IC's, amazing technology. I recognize the "Mickey Mouse" ears used for the "floating well" needed for the bootstrapped floating FET drive :-)
