T60似乎卖到4.5w左右的，无法接受如此高端的笔记本电脑出现如此情况～
在研发阶段还无所谓，成品机器还弄成这样。。。
丢脸的说～飞线事件
今天收到了来自大和实验室（YAMATO）笔记本ECAT部门经理对于T60飞线的说明，全文如下：
The yellow wire(jumper wire) solution is part of functional quality improvement purpose before integrating the circuit into new PCB.
在将芯片整合到新的PCB板之前，采用黄线（飞线）解决方案的目的是提高功能模块质量。
At first, regarding the product quality, we have completed adequate process/product qualification for both "with this yellow wire" and "w/o yellow wire". The qualification is not only system level but also PCBA level testing which includes all sets of reliability testing( ATC( Thermal Cycle)/THB( Thermal Humidity & Bias)/HT(High Temp Storage Test)/Mechanical Shock/Vibration testing ,, etc). Thus ,we have no quality/reliability concern on this product even with "yellow wire solution". And there is no differences from functional/quality point of view.
首先，就产品质量而言，不论是“采用黄线”还是“不采用黄线”，我们均已经完成充分的流程和产品品质检验。品质检验不仅是系统级的，也是PCBA级别的测试，这包括全套的可靠性测试（ATC热能循环测试、THB(Thermal Humidity & Bias)测试、HT高温存储测试、机械震动测试，等等）。因此，就使用“黄线解决方案”而言，我们并不担心存在质量或者可靠性方面的问题。从功能或者质量的观点来看，这也没有什么区别。
In terms of process control , we have followed IPC 610 standard with tight process control for quality of product. We build the PCBA by using only our qualified MFG line with adequate process/operator workmanship control , and the process fully validates industry standard.
从流程控制的角度来讲，我们遵循了IPC 610标准对产品质量进行了严格的流程控制。我们是在自己有品质保证和有充分流程及操作工艺控制的生产线上完成PCBA的制作的，所有流程完全符合工业标准。
As I stated in the above, the yellow wire is for fix the problem w/o any reliability risk and for product quality improvement purpose in new product phase. Wiring method has formal rule( tight control) inside IBM(lenovo), it can be applied only for non critical circuit,, such as reset , pull-up. Jumper,, etc,, and NOT for critical signals which requires impedance/Dk control.. Thus, No quality problem, No reliability concern on this wire itself. This means no differences between "integrated PCB" and "PCB with yellow wire" ,, from functional/quality view point.
如我在以上所说的，这根黄线所解决的问题是在新产品阶段提高产品的质量，并不存在可靠性方面的风险。在IBM（Lenovo），采用黄线有着正式的要求（严格的控制），仅仅只能被应用于非关键芯片，例如复位、上拉、跳转，等等。决不会被用于那些需要阻抗/DK控制等的关键信号。因此，就这根线本身而言，不会带来质量问题，也不会影响产品的可靠性。换言之，从功能和品质的角度来讲，T60不论是使用“整合的PCB”还是“采用了黄线的PCB”，没有什么区别。
I would like to say some history of ThinkPad PCBA for your reference ,, This yellow wire method has been used from the begining of IBM PC/Thinkpad product more than 18 years.. No difference for 18 years while I have been working for "ThinkPad PCB/PCBA design and quality".. and now it has already been in the industry standard.
这里我也愿意和大家聊一聊ThinkPad PCBA的一些历史以供参考。（采用黄线并非自T60开始，）从IBM PC/ThinkPad产品的最早期到现在，黄线都曾经被使用过，有超过18年的历史了。我工作在“ThinkPad PCB/PCBA设计与质量”部门的这18年来，没有什么区别。并且采用黄线这种方式，现在也已经是一种工业标准。
