THE SOLDERING METHOD USED FOR CHIPS (AND OPTIONAL HEATSINK GROUNDING) SOLDERING IS IMPORTANT WHEN SELECTING A THERMAL INTERFACE MATERIAL (TIM). 2(A) HAND SOLDER 2(B) WITH VICOR 40325 METHOD - THE PHASE-CHANGE TIM SHOWN IN THESE ILLUSTRATIONS MAY BE DAMAGED BY ONLY THERMAL GEL (SEE NOTE 2) TEMPERATURES OVER 125C, SO TWO ASSEMBLY PROCEDURES ARE DESCRIBED BELOW: (A) FOR HAND-SOLDERING ONLY, DUAL 11MM 40518 40526 3623 (B) FOR WAVE-SOLDERING AND/OR HAND-SOLDERING. DUAL 19MM TBD TBD (A) PLACE BOTTOM-SIDE HEATSINK (WITH PRE-ATTACHED PHASE-CHANGE TIM) ON PCB. B B PLACE CHIP AND TOP-SIDE HEATSINK (WITH PRE-ATTACHED TIM AND GROUNDING TABS). HEATSINK SELECTION WHILE SUPPORTING PCB, INSERT PLASTIC PUSH-PINS THROUGH BOTH HEATSINKS AND PCB. (SELECT PROPER PUSH-PIN LENGTH FROM TABLE ON THIS DRAWING.) IMPORTANT: TO SET FINAL THICKNESS OF PHASE-CHANGE TIM ENSURE THAT THE ENTIRE ASSEMBLY IS RAISED ABOVE 65C FOR SEVERAL MINUTES. HAND-SOLDER ALL CHIP AND GROUNDING PINS. ADDITIONAL SOLDERING IRON HEAT PUSH-PINS PCB THK NOMINAL PCB THK PCB THK MAY BE REQUIRED TO COMPENSATE FOR LOSSES TO THE HEATSINKS. W/ SPRINGS COLOR RANGE MINIMUM MAXIMUM (100/BAG) (B) WAVE SOLDERING TEMPERATURES ARE UNSUITABLE FOR PLASTIC PUSH-PINS AND PHASE-CHANGE TIM, SO PARKER CHOMERICS GEL8010 IS RECOMMENDED AS A TIM. 1.143 MM TO 1.854 MM 1.041 MM 2.057 MM 32436 BLUE APPLY A UNIFORM .003 (.076MM) LAYER OF TIM TO THE TOP AND BOTTOM SURFACE .045 TO .073 .041 .081 OF THE CHIP, OR TO THE CORRESPONDING HEATSINK SURFACES. PLACE BOTTOM-SIDE HEATSINK, CHIP, AND TOP-SIDE HEATSINK ON PCB. WITH A CUSTOM FIXTURE APPLY APPROX. 10 LBS LOAD TO THE TOP-SIDE HEATSINK AND THEN 1.880 MM TO 2.438 MM 1.676 MM 2.692 MM 32437 GRAY WAVE-SOLDER ALL PINS074 TO .096 .066 .106 REMOVE FIXTURE AND INSERT PLASTIC PUSH-PINS THROUGH BOTH HEATSINKS AND PCB.
