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 40519 40527 4623 (B) FOR WAVE-SOLDERING AND/OR HAND-SOLDERING. DUAL 19MM 40408 - DUAL 11MM 40520 40528 (A) PLACE BOTTOM-SIDE HEATSINK (WITH PRE-ATTACHED PHASE-CHANGE TIM) ON PCB. 6123 DUAL 19MM 40409 - PLACE CHIP AND TOP-SIDE HEATSINK (WITH PRE-ATTACHED TIM AND GROUNDING TABS). B B WHILE SUPPORTING PCB, INSERT PLASTIC PUSH-PINS THROUGH BOTH HEATSINKS AND PCB. (SELECT PROPER PUSH-PIN LENGTH FROM TABLE ON THIS DRAWING.) HEATSINK OPTIONS 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 MAY BE REQUIRED TO COMPENSATE FOR LOSSES TO THE HEATSINKS. PUSH-PINS PCB THK NOMINAL PCB THK PCB THK W/ SPRINGS COLOR (B) WAVE SOLDERING TEMPERATURES ARE UNSUITABLE FOR PLASTIC PUSH-PINS AND RANGE MINIMUM MAXIMUM (100/BAG) PHASE-CHANGE TIM, SO VICOR TIM 40325 (PARKER CHOMERICS GEL8010) IS RECOMMENDED. APPLY A UNIFORM .003 (.076MM) LAYER OF TIM 40325 TO THE TOP AND BOTTOM SURFACE 1.143 MM TO 1.854 MM 1.041 MM 2.057 MM OF THE CHIP, OR TO THE CORRESPONDING HEATSINK SURFACES. 32436 BLUE .045 TO .073 .041 .081 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 WAVE-SOLDER ALL PINS. 1.880 MM TO 2.438 MM 1.676 MM 2.692 MM REMOVE FIXTURE AND INSERT PLASTIC PUSH-PINS THROUGH BOTH HEATSINKS AND PCB. 32437 GRAY .074 TO .096 .066 .106 (SELECT PROPER PUSH-PIN LENGTH FROM TABLE ON THIS DRAWING.)
