I grew up taking things apart and I see no reason to change now. So, I made fixtures to make it fairly easy to remove tops from TO-5 and TO-8 metal IC packages using a Dremel motor tool and diamond cutting/grinding tools. (I can also cut the tops off of TO-3 cases without needing any fixture).
I then built an adapter to mount my digital camera to one side of a stereo microscope. This allows me to take pictures of of the opened chips.
So far I have taken pictures of these:
DH0008 Solenoid driver (in TO-5 case)
HA2-2630-2 High speed analog buffer (in TO-8 case)
LM121 Precision amplifier (in TO-5 case)
PA10 Apex power op-amp (in TO-3 case).
RFPIC12C509AF 18-pin DIP PIC microcontroller with RF transmitter circuit
RFPIC12C509AG 20-pin DIP PIC microcontroller with RF transmitter circuit
C1702 2K EPROM (256x8)
D2732A 32K EPROM (4Kx8)
My original intent was to upload these photos to this site but they are too big. The size is needed to see the details such as the "bits" in the EPROM's. Since I don't want to downsize the pictures, I put them here:
