IBM時代ThinkPad不少機型都有過飛線，沒人Care，這次

Lenovo是給對手炒的。

大和實驗室就T60飛線問題的說明 ZT

今天收到了來自大和實驗室（YAMATO）筆記本ECAT部門經理對於T60飛線的說明，全文如下：

--------------------------------------------------------------------------------

The yellow wire(jumper wire) solution is part of functional quality improvement purpose before integrating the circuit into new PCB.
在將芯片整合到新的PCB板之前，采用黃線（飛線）解決方案的目的是提高功能模塊質量。
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，就產品質量而言，不論是“采用黃線”還是“不采用黃線”，我們均已經完成充分的流程和產品品質檢驗。品質檢驗不僅是係統級的，也是PCBA級別的測試，這包括全套的可靠性測試（ATC熱能循環測試、THB(Thermal Humidity & Bias)測試、HT高溫存儲測試、機械震動測試，等等）。因此，就使用“黃線解決方案”而言，我們並不擔心存在質量或者可靠性方麵的問題。從功能或者質量的觀點來看，這也沒有什麽區別。
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.
從流程控製的角度來講，我們遵循了IPC 610標準對產品質量進行了嚴格的流程控製。我們是在自己有品質保證和有充分流程及操作工藝控製的生產線上完成PCBA的製作的，所有流程完全符合工業標準。
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.
如我在以上所說的，這根黃線所解決的問題是在新產品階段提高產品的質量，並不存在可靠性方麵的風險。在IBM（Lenovo），采用黃線有著正式的要求（嚴格的控製），僅僅隻能被應用於非關鍵芯片，例如複位、上拉、跳轉，等等。決不會被用於那些需要阻抗/DK控製等的關鍵信號。因此，就這根線本身而言，不會帶來質量問題，也不會影響產品的可靠性。換言之，從功能和品質的角度來講，T60不論是使用“整合的PCB”還是“采用了黃線的PCB”，沒有什麽區別。
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.
這裏我也願意和大家聊一聊ThinkPad PCBA的一些曆史以供參考。（采用黃線並非自T60開始，）從IBM PC/ThinkPad產品的最早期到現在，黃線都曾經被使用過，有超過18年的曆史了。我工作在“ThinkPad PCB/PCBA設計與質量”部門的這18年來，沒有什麽區別。並且采用黃線這種方式，現在也已經是一種工業標準。
