2.3 RECOMMENDED LAND PATTERN FOR PUSH PIN HEAT SINK
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
edgeâtoâedge spacing, and 0.50 (0.020)
clearance between Vicor heat sinks.
(B) Minimum recommended pitch is 25.50 (1.004).
This provides 9.00 (0.354) component
edgeâtoâedge spacing, and 2.00 (0.079)
clearance between Vicor heat sinks.
3. Vâ¢I Chip⢠module land pattern shown
for reference only, actual land pattern may differ.
Dimensions from edges of land pattern
to pushâpin holes will be the same for
all half size Vâ¢I Chip products.
4. RoHS compliant per CSTâ0001 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. Heat sink orientation and
device pitch will dictate final grounding solution.
