Re: Let's talk about BGA Chip suppliers
just got another order from goldenchipset. i needed a stencil the most for a notebook with intel n2840 cpu that has cpu nb sb all in one.
after put balls on stencil, i use hot air and balls melted, but noticed something strange.. some balls didnt go down perfectly. i lifted stencil to see what was going on and as my surprice, of all the balls, just 4-5 well ok, but 3-4 balls ripped off pads on bga, and all other balls stayed in the hole of stencil.
now bga is gone and gc want to resent stencil for free, but to use on what bga ?
here is a video that proove that stencil was 100% bad...
