Thermal/Mechanical Specifications and Design Guidelines
2.1.1
Package Mechanical Drawing
shows the basic package layout and dimensions. The detailed package
mechanical drawings are in
. The drawings include dimensions necessary to
design a thermal solution for the processor. These dimensions include:
1. Package reference dimensions with tolerances (total height, length, width, and so
forth.)
2. IHS parallelism and tilt
3. Land dimensions
4. Top-side and back-side component keep-out dimensions
5. Reference datums
6. All drawing dimensions are in mm.
2.1.2
Processor Component Keep-Out Zones
The processor may contain components on the substrate that define component keep-
out zone requirements. A thermal and mechanical solution design must not intrude into
the required keep-out zones. Decoupling capacitors are typically mounted to either the
topside or land-side of the package substrate. See
for keep-
out zones. The location and quantity of package capacitors may change due to
manufacturing efficiencies but will remain within the component keep-in. This keep-in
zone includes solder paste and is a post reflow maximum height for the components.
