Grasp of Defect Material and Defect Material Analysis 不良品掌控 及 不良品分析 Marco View in Appearance (外部巨觀解析) 根據AOT的量測數據, 產品翹曲有過大現象. 量測值:2.1mm 客戶規格: 1mm

Grasp of Defect Material and Defect Material Analysis 不良品掌控 及 不良品分析 (D2-A). Reason(s) for Inspection-escaped of Defect Material (漏放不良品之原因) 1.確認影響批是否有生產異常或修機記錄。 結果: 無發現異常記錄。 2.確認影響批的檢驗記錄是否有異常現象。 結果: 無翹曲超規之異常記錄, 檢驗數據為0.6~0.8mm, 均在規格內。

Containment Action Taken 暫時防堵措施之執行 D3 Containment Action Taken 暫時防堵措施之執行 1. 通知相關人員此異常事項, 並要求VI & OQC加強檢查, 以避免異常再發。 2.確認退回產品的異常狀況。 3.確認庫存是否有此異常現象, 以避免相同問題流出。 結果: 無發現相同缺點, 同時並寄出一批貨提供客戶作換貨動作。 In-charge Person 擔當者 Sophia Hsueh Date 2017/8/30

Analysis and Identification of Root Cause 要因分析及真因驗證 (D4-A). Fish-bone Chart (特性要因圖分析)

Analysis and Identification of Root Cause 要因分析及真因驗證 (D4-B). Identification of Root Cause 真因驗證 Process Mapping Calibration Curing Plating Transfer Mold Post Mold Cure Deflashing AOI Inspection Visual OQC IQC Packing Water rinse Identification: 由於確認生產記錄並無任何異常記錄, 且我們確認OQC檢驗記錄,其翹曲值也在規格內,故判斷這批貨可能是在OQC檢驗完後放置在常溫環境過久導致compound吸溼而造成翹曲變大。

Preventive Action Taken 預防措施之執行 D5 Preventive Action Taken 預防措施之執行 1. 訓練OP在AOI後每個製程完成後需將產品放置在防潮箱,避免產品吸溼。 Resp: PD-Yen Yu Due Date:9/20/2017 Status: Done 2. 訓練OQC在檢驗完成後必需將產品放置在防潮箱,避免產品吸溼翹曲。 Resp: QA-Jeff Huang Due Date:9/20/2017 Status: Done In-charge Person 擔當者 Yen Yu / Maggie Hsiao Date 2017/9/18
