Table 1-1. EPC-33/34 Environmental and Electrical Specifications.
The Intel specification for the IntelDX4 chip states that the chip casing must not
exceed 85°C. If ambient air temperature coming off the heat sink is below 42°C,
then no forced air cooling is required. Intel recommends 200 linear feet per
minute (lfm) air flow (60°C or below) for cooling purposes.
Vibration and shock specifications assume the EPC-33/34 is mounted as a single
board computer. See Figure 2-1 for mechanical dimensions.
