Unless otherwise stated on the drawing, etched micro-section photographs of pre and post Thermal Stress per IPC-TM-650 with interconnects, shall be provided with each lot in sufficient detail to show line of demarcation between the electroless copper subplate and the electrolytic copper plating to interconnects and barrel at the plated through holes. 100X minimum magnification is required, however, 500X magnification is preferred. Etched micro-sections and their photographs must be traceable to PO and part number of PWB. This requirement does not apply for 1-sided or 2-sided PWBs. Page 15 of 17

Unless otherwise stated on the drawing, the Tg of laminate and any filler materials to be minimum of 170ºC. Unless otherwise stated on the drawing, provide evidence of positive etch back of PTH prior to plating. Minimum 0.0002 to maximum 0.002 with target of 0.0005. Positive Etch- Back must be traceable to PO and part number of PWB. This requirement does not apply for 1-sided or 2-sided PWBs. Positive E 18. POWER PARAGON, INC. (PPI) MARKING REQUIREMENTS. A. Part marking requirements per MIL STD 130 (Ref. PS-0033) 19. RECORDS RETENTION A. (Incorporated into General Note 14) B. The manufacturing, inspection and test records for product delivered under this PO are considered life time records ; therefore the supplier shall notify PPI if their records retention process cannot support the life time maintenance requirement. In this case, the supplier shall keep and maintain the records for the period specified in their internal procedures. At the end of that period, the supplier shall forward the records to PPI for life time retention. 20. PROCESS QUALIFICATION REQUIREMENTS A. Qualification of Welding/Brazing Procedures and/or qualification of Welding Personnel are required. The supplier shall contact PPI buyer for detail of requirements. B. Qualification and Approval of Printed Wiring Assembly (PWA) processes and procedures are required. Solder IAW J-STD-001 and PS-0102, PS-0106 and PS-0122 as applicable. The supplier shall contact the PPI buyer for detail of requirements. C. PWAs and Components shall meet the cleanliness requirements of J-STD-001 for NaCl. NOTE: that there are several measurement methods that yield different nominal results depending on the test methods utilized (see J-STD-001). Supplier shall track production averages for evidence of significant deviations and maintain records of process corrections. D. Submittal of Welding and Brazing Procedures. Supplier shall submit copies of welding (for example: fusion, spot, projection and seam) and brazing procedures (for example: torch and dip) for each individual type of welded or brazed joint for approval prior to the start of production welding/brazing.

21. INTERPRETATION OF LIMITS A. All specified limits for machining services and for dimensional control of deliverable parts and assemblies shall be interpreted as absolute limits as defined by ASTM E29, Standard Practice for Using Significant Digits in Test Data to Determine Compliance with Specification. For all other observed, measured or calculated product characteristics (e.g. for material suppliers, material distributors, and services other than machining/dimensional control) specific limits shall be interpreted using the rounding method as defined by ASTM E29. 22. SUBSTITUTION A. Any substitute called out on the associated Parts List/Bill-of-Material is not allowed to be utilized in the assembly without prior authorization from PPI. Any alternate process called out on the drawing or parts list/bom is not allowed to be utilized without prior authorization from PPI. Supplier shall submit the request to utilize alternates or substitutes using an SDAR (Supplier Discrepancy Action Request) form. B. No single-item component on a PO is allowed to be substituted without prior authorization from PPI. Supplier shall submit the request using an SDAR (Supplier Discrepancy Action Request) form. 23. MARKING & PACKAGING OF COMPONENTS USED FOR QUALIFICATION TESTS A. When components or parts are sent to a Lab for qualification tests, the Lab after performing the tests shall ship the components back to PSG in special color bags clearly labeled that the parts were subject to qualification tests and that they are not to be used for production.
