2.3 RECOMMENDED LAND PATTERN FOR PUSH PIN HEATSINK
Notes:
1. Maintain 3.50 (0.138) Dia. keep-out zone
free of copper, all PCB layers.
2. (A) minimum recommended pitch is 24.00 (0.945)
this provides 7.50 (0.295) component
edge–to–edge spacing, and 0.50 (0.020)
clearance between Vicor heat sinks.
(B) Minimum recommended pith is 25.50 (1.004).
This provides 9.00 (0.354) component
edge–to–edge spacing, and 2.00 (0.079)
clearance between Vicor heat sinks.
3. V•I Chip land pattern shown for reference
only, actual land pattern may differ.
Dimensions from edges of land pattern
to push–pin holes will be the same for
all half size V•I Chip Products.
4. RoHS compliant per CST–0001 latest revision.
5. Unless otherwise specified:
Dimensions are mm (inches)
tolerances are:
x.x (x.xx) = ±0.3 (0.01)
x.xx (x.xxx) = ±0.13 (0.005)
6. Plated through holes for grounding clips (33855)
shown for reference, Heatsink orientation and
device pitch will dictate final grounding solution.
