    LIST of U7000 PINS

    More of a copy and paste to make it easier. May not need all of them I found myself needing it just to make notes

    820-3115 B No green light on Magsafe

    I will post those when I get home. Do CHGR_SGATE and CHGR_AGATE normally get shorted to ground so that the voltage dividers (R7085/R7086 and R7080/R7081) can fully open Q7085 and Q7080?

    PP3V42_G3H is good at 3.43 at the one wire circuit PP_BUS_G3H: 0V PPDCIN_S5_CHGR: 18.5V CHGR_ACOK = 0 V U7000 RES PINS 27-28: 20.3 Ohm RES PINS 17-18: 3.2 Ohm 2: 17.42V 3: 4.32 V 10: 3.47 V 11:3.47 V 14: 0 V 19: 5.09 V 20: 4.93 V R7010: 7.6 K which seems low but ACIN (PIN 3) seems good...

    General question about reflow

    I have been practicing for a few hours every day on dead boards, removing and replacing QFNs I had settled on a general procedure and I was looking for guidance I am using a QUICK hot air station 1)I start at a high temp 600-615C at 3-4 inches from the board at high flow rate (100 on the...

    And: R7013 is missing completely ? any idea why. It is not a NOSTUFF on this board

    820-2850 A No PPBUS_G3H

    "R7011: 330 Ohm" Do you mean onboard value? "C7011: 0 uF" I was not thinking on its capacity... Were you asking about short to ground or? Sorry, new to this but I do appreciate your time. After your response I usually spend time looking at the schematic to figure how and why to ask the same...

    R7010: 4 kOhm R7011: 330 Ohm C7011: 0 uF R7013 is missing completely which makes no sense to me (I double and triple checked) R7012: 1 kOhm
