Fig2-1. Installation of Printed Circuit Board and Heatsink
1 Method to Fix
To fix a power module onto printed circuit board, use M3
screws and mount it to the tapped holes (2 places) of the
module. Recommended torque is 0.54N･m.
2 M3 Mounting Tapped Holes
M3 mounting tapped holes of power module are connect-
ed to baseplate. Connect baseplate terminal to FG (Frame
Ground) by using this M3 mounting tapped holes.
3 Mounting Holes on Printed Circuit Board
Refer to the following sizes when determining diameter of
hole and land diameter of printed circuit board.
PAQ100S48/B
Input/Signal terminal pin (φ1.0mm)
Hole diameter: φ1.5mm
Land diameter: φ2.5mm
Output terminal pin (φ1.5mm)
Hole diameter: φ2.0mm
Land diameter: φ3.5mm
M3 Mounting Tap (FG)
Hole diameter: φ3.5mm
Land diameter: φ5.5mm
4 Clearance from Customer Board
Minimum clearance between PAQ100S48/B and a cus-
tomer board is 1.5mm
The power module may influence by noise, care must be
taken when wire the signal line.
3. Heatsink Installation Method
1 Method to Fix
To fix the power module onto heatsink, use M3 screws and
mount it to the tapped holes (2 places) at the baseplate
side. Recommended torque is 0.54N･m.
Use with thermal grease or thermal sheet in between heat-
sink and baseplate to minimize the contact thermal resis-
tance and to enhance the heat conductivity. Also use the
no-warped heatsink and make sure good contact between
baseplate and heatsink.
2 Mounting Hole of Heatsink
The recommended mounting hole diameter of the heatsink
is φ3.5mm.
4. Vibration
The vibration specification of the module is determined as-
suming that only the power module is mounted on printed
circuit board. To prevent excessive force to the module
aud the printed circuit board, fix the heatsink to the chas-
sis as well as to the module when a large size of heatsink
is used.
