mbrp30045ct www. onsemi.com 3 mounting procedure the powertap package requires special mounting considerations because of the long longitudinal axis of the copper heat sink. it is important to follow the proper tightening sequence to avoid warping the heat sink, which can reduce thermal contact between the powertap and heat sink. 2 ? 3 turns 2 ? 3 turns 2 ? 3 turns power tap heat sink step 2: finger tighten the center bolt. the bolt may catch on the threads of the heat sink so it is important to make sure the face of the bolt or washer is in contact with the surface of the powertap. 2 ? 3 turns finger-tight 2 ? 3 turns power tap heat sink step 3: tighten each of the end bolts between 5 to 10 in-lb. power tap heat sink 5 ? 10 in-lb finger-tight 5 ? 10 in-lb step 4: tighten the center bolt between 8 to 10 in-lb. 5 ? 10 in-lb 8 ? 10 in-lb 5 ? 10 in-lb power tap heat sink step 5: finally, tighten the end bolts between 30 to 40 in-lb. 30 ? 40 in-lb 8 ? 10 in-lb 30 ? 40 in-lb power tap heat sink step 1: locate the powertap on the heat sink and start mounting bolts into the threads by hand (2 or 3 turns).
