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.

在将芯片集成到新的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 pron is part of functional quality improvement
purpose before integrating the circuit into new PCB.

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。

why everybody care it that much

ibm的研发中心在鬼子那里

TOP

心里面没底了,到底是怎么回事啊

TOP

估计是鬼子的。

在日本?

TOP

“大和实验室”,是哪里的实验室?联想的实验室?

TOP

虽然没什么问题,

但是看着总是觉得不舒服

TOP

心里面没底了,到底是怎么回事啊?

TOP

真的假的?我不是电子电路专业的。
我记得看过一片文章,非官方的文章介绍了一下这个黄线的电路原理,我记得目的就是为了降低电路抗阻。

而这里却说不是。

真不知道该信谁的。
