If you told me you use fuming sulfuric we would tell you that your devices are dirty but you get your job done ;) We mean we dont want to explain in details why we mix chemicals together to better break down the various barriers protecting the die.

I do this all the time, it's not a secret process, it's a well known industry standard practice. I am not trying to be a dick, but by saying that it's some sort of secret you were just begging to get called out. When you say proprietary process, you mean fuming sulfuric acid and a hot plate.

Also, it seems that the web lacks nice hi-res images of that masterpiece. Thanks! Hi guys,

Three buttons on the right: 1) Top button would show the date and month for a few seconds.. 2) Middle allowed you to set date and time 3) Bottom switched on a light (cont. from my last comment)

If you do intend to magnify a watch circuit, don’t pick any fancy new watches.. go for that cheap old tech which were very common. Three buttons on the right:

1) Top button would show the date and month for a few seconds..

I mean the magnified view. For how cheap they were available back in the day (even in the 80s the very cheap ones cost $1), they were a marvel. The IC typically was not packaged, but had a blob of resin on it. http://www.mrsec.wisc.edu/Edetc/nanolab/watch/ I'm sure any kid with a little bit of imagination has taken one apart after it stopped working :) I’ve always wanted to see what was under the resin in those really cheap 80s digital watches.. those with the four 7-segment and ‘:’ liquid crystal.

If there is enough interest in this, we can produce a write-up on this process. Regards You can manually polish (lap) the layers off using a very fine lapping film or solution.
