​​

13. M-SC (Quality Score)

  1. All purchase orders will be subject to SDI’s Vendor Scoring System and the Q-note shall be included on all Purchase Orders.

  2. Quality Scores shall be determined by:

    1. On-Time Delivery

    2. Compliance with Purchase Order Requirements

    3. Quality of received products and services

  3.  On-Time Delivery

    1. On time delivery is a key component in scoring the status of a vendor.  All purchase orders are expected to have an expected delivery date connected to them.

    2. Multiple line items may have different dates.  Large quantity items may have staggered delivery schedules.  These should be clearly communicated from the vendor at the time of purchase.

    3. On Time Delivery is based on a graduated scale and is scored as follows:

      • Days late   Score

      • < 3              100%

      • 4-6              75%

      • 7-9              50%

      • 10-12          25%

      • >12              0%

  4.  Compliance

    1. Compliance to purchase order requirements are an important factor in determining a vendor overall Quality Score.

    2. Compliance is based on the following three criteria, which are averaged to obtain a compliance score:

      1. Receipt of a Certificate of Conformance (C of C) (if requested).

      2. Accuracy of the C of C vs. Purchase Order Requirements.

      3. Compliance with Q-Notes listed on the Purchase Order.

    3. Compliance is also scored on a graduated scale as follows:

      • Compliance      Score

      • Pass                  100%

      • Borderline        50%

      • Fail                    0%

  5. Quality

    1. The overall quality of products and services received is vital to SDI and its end-use customers.  For this reason, the quality of products and services received are inspected closely.

    2. Each product will naturally have different criteria for quality, ranging from simply quantity received to more detailed physical and/or electrical analysis. 

    3. AQL Sampling is utilized for large quantity orders.  If a single failure in the sample fails any the criteria established for the product or service, the entire lot may be rejected and returned to the vendor for rework. Additionally, the percentage of accepted vs rejected parts are averaged with the AQL Sampling results to obtain a Quality score.

  6. Overall Quality Score

    1. On-Time Delivery, Compliance, and Quality Scores from each Purchase Order are averaged together to create the Overall Quality Score.  These scores are averaged with all other Overall Quality Scores from Purchase Orders received from the previous 24 months to obtain a Vendor Quality Score.

    2. Vendors may request their Overall Quality Score by contacting SDI's QA Manager.

14. M-SP (Special Processes)

  1. A special process is any process where the resulting output cannot be verified by subsequent monitoring and measurement and deficiencies become apparent only after the product is in use or the service has been delivered.

  2. Suppliers must have specific, documented, and controlled procedures for each special process performed.

  3. Only qualified/certified personnel shall be assigned to perform a special process.

  4. The supplier must develop a specific training plan and check the performance of the individual associate on a regular basis.

  5. SDI reserves the right to request, review, and approve all special process procedures, training documents, and certification records.

  6. Special processes include, but are not limited to:

    • Coating (Conformal, Diffusion, Painting)

    • Electroplating

    • Heat Treatment

    • Laser Drilling, Cutting and Marking

    • Non-Destructive Testing (NDT)

    • PCBA (Printed Circuit Board) assembly and manufacturing

    • Soldering

    • Seam Sealing
