Mounting Instructions Power Modules
Pierre-Laurent Doumergue Engineer Advanced Power Technology Europe Chemin Magret 33700 France Introduction: This application note gives main recommendations appropriately connect power module onto heat sink, (Printed Circuit Board), bars wires power module. very important follow mounting instructions limit both thermal mechanical stresses. Power module mounting onto heat sink. Proper mounting module base plate onto heat sink essential guarantee good heat transfer. heat sink power module contact surface must flat (recommended flatness <50µm 100mm continuous, recommended roughness clean dirt, corrosion, damage) order avoid mechanical stress when power module mounted, avoid increase thermal resistance. Thermal grease application achieve lowest case heat sink thermal resistance, thin layer thermal grease must applied between power module heat sink. grease applied onto module base plate, minimum thickness 100µm (3.9 mils) grease should applied with roller spatula. grease applied onto heat sink, recommended screen printing technique ensure uniform deposition minimum thickness 100µm (3.9 mils). case, module bottom surface must completely with thermal grease. wetted
Mounting power module onto heat sink. Place power module above heat sink holes, apply small pressure Insert screw with lock flat washers each mounting hole screw used instead M6). screw length must least (0.6"). First lightly tighten four mounting screws. Tighten alternatively screws until their final torque value reached (between N.m, 2.21 3.69 recommended screwdriver with controlled torque this operation. possible, screws tightened again after three hours. quantity thermal grease correct when small amount grease appears around power module once bolted down onto heat sink with appropriate mounting torque (see figure screws tightened with mounting torque N.m, 2.95 Figure shows thermal grease module base plate when removed from heat sink. Screws tightened with mounting torque N.m.

Connection pull forces. Power modules must mounted such that resulting pull forces limited 200N (44.96lbf) power terminals limited (11.24lbf) signals terminals. This acceptable maximum value pull force vary depending mounting operating conditions. 200N 200N 200N
Conclusion: This application note gives main recommendations regarding mounting modules. Applying these instructions will help decreasing mechanical stress both PCB, bars wires power module therefore will ensure long term operation system. Mounting instructions heat sink must also followed achieve lowest thermal resistance from power chips down cooler. these operations essential guarantee best system reliability achieve highest possible MTBF (Mean Time Between Failure).
