bad apples

i’ve seen a few defective apple ibooks recently … and had to solder one last week: there’s a little chip with 28 pins on the bottom of the logic board, the quality of the solder-job was so bad or the heat so intense that one pin (#28) came loose

instead of putting shims between the case and the chip i would recommend soldering: the shim pushes the chip onto the logicboard but not the pins – unless you make a shim with a hollow center …

anyways you need a steady hand, a good magifying glass but no extra solder! just let things flow a bit, takes only a sec or two per pin, but it’s a tedious job cause everything is so small!
