    Tips geting oxidized when using wick

    Hi, i have weird problem - when i'm using soldering wick to clean BGA balls under CPU or PCH on motherboard my tips(different types) getting oxidized very fast and lost all power.
    i Was trying different types of wick, flux - no difference. I can't even clean one full socket and i need to use deoxidizer in half-time.
    Temperature: 350-365celsius
    station: jbc cd-2bqe
    Wick: edsyn
    flux: warton hf rework jelly
    Do you have any tips?

    While get it to wick, use big wide flat tip which allow you to lower tip temperature due to biger surface of heat transfer. Otherwise, use preheater, heatgun, and also lower the tip temperature in order to prevent excess tip oxidation.

        Maybe you got El Cheapo tips or a way too small tip. That will do it too.

          350 sounds o.k. for temp,
          i suspect it's the flux doing it.
          you need to clean and tin the tip a lot if your using braid - it's a common issue

          i presume your using a blade style tip so contact area wont be an issue either.

            Quality solder iron tips and Kapton ?
            by corrize
            Hello, I have a solder iron pen (50w) with tips « 900m » (hollows ones, standard). I'm searching to replace mines because it's impossible to tin, they remain black and impossible to unsolder a mini SMD capacitor with. Bad ones.

            I'm looking to replace the iron tips but, on Amazon, Ebay… all no names, the sames. Sold by 10, 15 or more at low price and « pro » websites only one Hakko tips sold 20 dollars. I'm lost.
            Do you have brand of qually tips pls ?

            Same question for Kapton (for my other hot air iron), do you have brand or good place to buy, the true...

            Tips on how to remove a very stuck memory chip on a GPU?
            by woody-009
            Hi Everyone

            I'm after some tips on how to remove a VERY stuck memory chip on an RTX2070. I am a beginner with this size chip so I bought an old non working GTX960 and I can remove and refit the memory chips to that with ease.
            So far I have cranked my hot air station to as high as it will go (It says 450C but I have no way to confirm that but its hot... its a cheap ebay unit. And I have a large square nozzle and have tried smaller nozzles.) I cant get the solder balls under the chip to melt. It has taken some flux in under it but still wont move. I have chipped one of the...

            Tips for reduce shaking ?
            by corrize
            Hello, I have a little problem. When I use hot air, I'm shaking a little with tweezers, and I'm scared to push a little qfn for check if it floating. So sometime, I prefer to not try and « hope » the solder is done.

            I use the blue tweezers mechanic AAC-14 and a I put just my fist on the table.

            Do you have tips to reduce shaking pls ? Maybe shorter tweezers, or something for wedge the fist or arm ?

            (I add : no coffee, no alcohol and I don't smoke).

            Need help with troubleshooting tips\ schematics -LG monitor that goes off quickly
            by litec systems
            Hi all
            Does someone has the test points \ schematics for lg eax65543115 ( 22" version, lg led monitor)
            Or any ideas how to troubleshoot it?
            The screen turns on for like 10 seconds, then goes off ( kinda protection triggered, as it goes off like you've been pressing the power button)
            , but the cpu gets hot quickly within those 10 seconds , AND STAYS HOT EVEN WHEN IT'S OFF
            I'm suspecting it gets over voltage \ current and triggers some OV \ OC PROTECTION but hopefully it's not too late ( that the chip is broken)

            NOTE that it's a trashpicked monitor...
