My adventures in SMD miniaturization-land continue:
Those are two Atmel chips – an ATtiny85 (SOIC-8) and an ATtiny84 (SOIC-14).
Compared to 0603 parts, these are actually quite large. The distance between the pins is 1.27mm (0.05″), half of regular through-hole parts.
But you do need fine tweezers, and a ZIF socket to flash them or try them out without soldering is also nice:
The lid snaps down, making a firm connection with each of the 14 pins.
Hm, I see now that the SOIC-8 dimensions are a bit wider than the SOIC-14 package. So the smaller package doesn’t fit in this (pricey) ZIF socket.
So not only is this stuff small – it’s also easy to overlook such differences!
Fortunately there are datasheets.
