    Re: reballing problems

    Direct heat are the small ones that you leave on the chip after you put the balls on, and heat the chip with the stencil still in place.

    Indirect heat are the ones you put in a jig and lift away after you put the balls, then heat the chip to get the balls attached.

        BEST 505 Vs Mechanic Brand Reballing Balls with Lead
        by Stanley1843
        Hello,
        has anyone use these Brands of solder balls? The brand BEST writes on the label of the jar the specs of the solder balls instead of the Mechanic brand. I beleive that BEST brand must be more professional (in labeling at least) but I have never try one of them so I would like your opinion. By the way I hardly can I find the Mechanic brand in aliexpress (the only where I found was lead free solder balls) and on ebay these that I found are approximately15USD per jar. If you know any other trusted brand of solder balls please tell me.

        Z270 PCH Reballing help needed pls
        by petemanuk
        I'm trying to reball a Z270 PCH, i've got the right stencil for the PCH and it's direct heat type.

        I initially tried using 0.3mm solder balls (leaded type) but am having lots of problems with the balls not wetting to the chip, basically some of them just wont solder to the pads.

        I'm making sure the chip is as clean (using ipa) then putting a thin layer flux on then putting in in the holding jig with the stencil on. I'm the heating to about 400degC with minimal airflow (4% on my Atten) but some balls just refuse to stick!!

        I've repeated the above using...

        Each GPU reballing produces different MATS results, looking for root cause ?
        by DynaxSC
        Hi,

        I have an Nvidia card which makes me wondering, what is the root cause for Mats errors. The story is as follows:

        1. When I received the card Mats showed one memory with errors.

        2. Replaced the memory chip, but no change, still same error, so memory chip is ruled out.

        3. Made a carefull reballing of the GPU, MATS showed 3 memories with errors, the one before, and 2 other new chips.

        4. Made a second reballing of the GPU and Mats shows again only one memory chip with errors, the same on as in the beginning.

        5. Made...
