枫下家园 / 电脑用户 / 今天帮人修BIOS,惨败.那人的技佳主板,刷错了BIOS,可恨BIOS是焊在主板上的,小方块,32脚.
热风枪吹下来容易,写好BIOS再焊回去就不灵了 :-((
锡焊水平太弱,只好请顾客拿回家了... 白忙活了一下午.
发誓以后不给人焊BIOS!!!

连技嘉这样的大牌都偷工减料,不装SOCKET.真可恶.

才不是呢，在研发过程中，一定要尽量用socket，方便替换芯片，飞线改电路，成品后尽量使用表面贴，除了减少成本，更稳定是真的。

挖！其实我也都一根根连上了,相连的两个没有短路的(除了一对,拆下来一看,板上设计的就是短的)其他似乎都正常,就是不亮.

I don't think 热风枪吹坏的。大家都这么吹的啊。

烫久了难说. 不过也可能你把人家bios写坏了

我后来又焊下来,写了第二次, so I am quite sure the chips is good.

I don't think you can do that. Almost all the MBs have 2~4 layers.

BIOS方芯片是向内弯曲的,表面焊接哟

据俺所知，6 or 8层更象真的主板:-)，不过总有焊盘，过孔在外面的:-)

Most of the MBs are 4 layers. More layers will have reliable problems in high frequency, and cost is high. Actually you won't able to know which pin is connected to other layers.

Actually I want to say keep trying. I never heard anyone can do that. I think I can do that but I don't have opportunity to do that. Make sure your tools are grounded and try not to touch MB while welding.

这活儿挣不了多少钱，又费劲又有风险，宜慎重
