Phone： Date：2015-5-6 RE： win deformation causing Flotaing on Board 由于产品不良给贵司带来的麻烦深表歉意，收到贵司的信息后，我们立即展开调查。 Very sorry for the defect makes you getting in trouble, while received your information, we investigated the matter immediately 反 馈 日： 2011-3-3 Feedback date: 2011-3-3 品 名： 1-842-700-11 ITEM NO: 1-842-700-11 不良内容： 组品平面度不良
Defect content: Pre-case founded win deformation causing floating on board 不良率： 7% Defect rate: 7%
発生原因(happen reason)
根据客户寄送的不良样品，内部用PCB板进行了确认。
1. 标示平面度在0.6mm以下所有样品，插入PCB后均没有翘起，是OK品。
2. 标示平面度超过0.6mm的所有样品，框架面明显变形，插入PCB后均有明显翘起，而且不能插入插板。
3. 框架面变形推定发生原因之一可能为工序中拿取不注意导致。工序F插座铆装或插板检验时拔取不规范可以再现类似的产品变形。 4. 另外还有可能为落下品混入。
The un-plat defect samples have been sent to my company, and confirm it with our PCB board.
Confirm result:
1. The marked un-flatness of the parts below 0.6mm seems no obvious gap between the parts and PCB. It is OK parts.
2. The marked un-flatness of the parts over 0.6mm bent obviously,the gap is very obvious between the parts and PCB after inserting into the PCB
3. We think the bent maybe caused for the careless when the part was take out from the jig in the caulking process. They can be reappeared for the abnormal operation when drawing off the parts in the F connector caulking or jig check process .
4. And also maybe it is the defect parts mixed which had been dropped to the floor before.
流出原因(outflow reason)：
1. 该产品的平面度没有在图纸上明确定义，因此内部并无列入管控。另外平面度小于
0.6mm的实际为OK品。
2. 平面度大于0.6mm（实际为变形所致）的产品
１）检查员漏检
２）可能插板插入后拔出不良，所以后续未有检验导致流出 。
1. For the flatness of parts has not been identified in the drawing, so We did not control in our process. and also actual the flatness below 6.6mm is ok after assemble with JIG. 2. the flatness of the parts over0.6 mm 1) Maybe the inspector miss-check it
2) it deformed when the parts were picked out from the jig by the inspector for the abnormal operation, then we pack it without check. So It flows out. 発生对策 (happen countermeasure)：
1. 跟SONY HQ制定平面度小于0.6mm为OK品的平面度标准并追加进图纸，我们内部制 程进行管控。
2. 教育作业员注意工序中的取用，按作业指导书垂直或两手水平拔取防止变形。
1. Make the flatness standard with SONY HQ and identify the standard in the part drawing.
when the flatness is smaller than 0.6mm,it is ok. we control it in our process.

2. Train the operator to pay more attention when pick out the parts in the caulking and jig
check process. Require them to draw out the parts vertically according to the SOP to prevent the deformation of the parts.
2011-4-1 流出对策(outflow countermeasure)：
１）对在库和今后生产的产品进行治具全检。检查实施产品标示”平面度検査実施品”
后出货。
For the parts in store and new parts we will implement 100% flatness jig check. We implemented it from the shipping lot 2011-4-26.
Jig check Shipment mark 由于我司的产品不良给贵司带来不便在此深表歉意！我司会在后续生产严格按照改善措施执行,再次感谢贵司的支持和指导!
We are very sorry for the defect makes you getting in trouble, thank you for your support and guidance!
合作愉快！
