Delta模組不良現(xiàn)象，返回調(diào)焦站Check，再確認原始調(diào)焦數(shù)據(jù)。

以5PCS為例如下：小結(jié)：成品Delta不良拿至調(diào)焦站Check確認均有跑焦現(xiàn)象，下一步查找跑焦原因。扭力測試確認分別取10PCS成品站OK模組&DeltaNG模組測試扭力對比小結(jié)：DeltaNG模組扭力測試均OKD5S02C扭力測試對比(gf.cm)SPEC:>160gf.cm序號1#2#3#4#5#6#7#8#9#10#OK模組扭力220210230250220250230220210240NG模組扭力210220250250235205240210215230試驗步驟測試不良值。左旋轉(zhuǎn)鏡頭約5度，分別旋轉(zhuǎn)兩次測試其值?；氐皆c右旋轉(zhuǎn)鏡頭約5度，分別旋轉(zhuǎn)兩次測試其值。左旋右旋小結(jié)

1.按此方法驗證10PCS結(jié)果都是可以通過重新右旋鏡頭PASS。

2.初步確認是鏡頭末調(diào)節(jié)最佳位置，或流程中觸碰鏡頭導致跑焦。旋轉(zhuǎn)鏡頭驗證調(diào)焦&Check數(shù)據(jù)對比取5PCS不良模組，每PCS模組做調(diào)焦&Check，重復5次，對比調(diào)焦前后是否存在差異。結(jié)論：調(diào)焦前后變異不大，排除調(diào)焦機自身原因造成
