Die size 15.12x4.39 mm.



Inkjet nozzles on a Kapton tape are likely ion-etched, laser drilled holes should have been much less perfect. On the other hand positions of nozzles are slightly not regular.


Nozzle diameter is 25µm, nozzle pitch is 75µm.

<![CDATA[Noname LED blinker : weekend die-shot]]> http://zeptobars.com/en/read/noname-LED-blinker
Chip internals are more complicated than one would imagine - there are 5 LED channels, only 2 of which are used here. Layout resembles other blinkers we've seen in the past (flicker, RGB). It's fascinating that there is a company somewhere specialized in making LED blinkers of various kind and doing just fine.

Die size 587x479 µm.

<![CDATA[Ti NE5532 - real vs fake : weekend die-shot]]> http://zeptobars.com/en/read/Ti-NE5532-real-vs-fake-opamp
Genuine Ti NE5532 has die size of 2103x2154µm.


Fake Ti NE5532 is much smaller and have much simpler design. Bare minimum to operate as opamp:

SnipTheCat at EEVBlog forum noticed that these have much slower slew rate vs datasheet.

This IC was from one of these "Ti NE5532 100pcs for 4$" ebay lots. On the back side it was marked as "Tdsemic", which probably means it was manufactured/packaged at 拓电半导体(香港)有限公司 (TD SEMICONDUCTOR LIMITED.).
