19各製程(錫膏印刷, 置件, 迴焊, 組裝, 測試, 重工等)是否以DOE或其他統計手法給予最佳化?
22貴司是否識別及文件化主要的製程風險, 該製程風險必須管制在貴司"無鉛"製程中, (例如:鋼板開法, PCBA設計變更, profile 溫度參數, 氮氣之使用, 檢驗標準, "有鉛""無鉛"的料號區分管制等)

19. Has each step of the assembly process (screen print, placement, reflow, fabrication, assembly, test, rework, etc.) been optimized by the use of a DOE or other statistical process tool?
20. Are the DOE plans and results documented to support your optimized process settings?
21. Are your optimized process and assembly settings documented in a procedure or specification?
22. Have you identified and documented the key manufacturing and process risks that must be controlled in your "Lead Free" manufacturing process (i.e. stencil design, PCBA design changes, temperature profile parameters, use of Nitrogen, inspection criteria, segregation from non-lead free material, etc)?
23. Do you have risk mitigation control plans identified for each risk?
24. Are you providing Dell a monthly status on the implementation of each risk mitigation control plan?
25. Higher assembly and rework process temperatures will require components to be controlled at higher MSL levels. Do you have documentation that identifies the MSL levels for all "Lead Free" components and assemblies for your Optimized "Lead Free" assembly process?
26. Do you have procedures, equipment, storage facilities, etc. in place to implement the appropriate controls for each MSL level ?
27. Do you have documentation or audit records to verify that the appropriate MSL controls are being properly implemented and controlled in your "Lead Free" assembly process?
28. Are MSL controls in place for components rejected from the SMT placement machines?

29. Do you have MSL controls in place for your "Lead Free" rework / repair process?
30. Has the pass / fail criteria for "Lead Free" assemblies been updated?
2007-06-25 17:33:56 補充：
31. Have the inspection procedures been updated for the new "Lead Free" pass / fail criteria?
32. Have the inspection and assembly training documentation been updated for the new "Lead Free" pass / fail criteria?
2007-06-25 17:34:17 補充：
33. Have all operating procedures and documentation been updated to include "Lead Free" product / materials segregation and handling requirements to prevent mixing "Lead Free" from "Lead Containing" product?
2007-06-25 17:34:24 補充：
34. Have all labeling and marking documentation or specifications been updated to include "Lead Free" labeling and marking requirements?
35. Do you have audit requirements and results to verify compliance with your "Lead Free" segregation and labeling procedures?
2007-06-25 17:34:33 補充：
36. Do you have a documented procedure to prevent returned "Lead Free" product (from Dell manufacturing lines or Field returns) from being mixed with "Lead Containing" product?
37. Is this procedure automated and not subject to failure caused by operator error?
2007-06-25 17:34:47 補充：
38. If you use more than one alloy of Lead Free solder for SMT, Wave Solder, or rework, then you must have procedures and controls in place to identify and segregate products with each alloy. Are these procedures and controls in place?
2007-06-25 17:34:56 補充：
39. SQE 8.1 Do you have a corporate specification requiring unique part numbers for Lead Free components and materials from your sub-tier suppliers?
2007-06-25 17:35:03 補充：
40. Do you have a corporate specification or procedure requiring a new part number for Lead Free assemblies shipped to your customers?
41. Have all for your internal BOM structures been modified to identify lead free components and materials?
