Statement of Shelf Life For Solderability

Products finished with electro-plated matte tin (finish designations ET and DT) will experience some loss of solderability over time. The optimal shelf life of any given lot of product varies with the characteristics of the tin plating and the storage environment. With this understanding, the following minimum shelf life times should be used for inventory management:

  • Solderable optimal shelf life of all ET and DT plated PEM products is 36 months from the date of the original packaging.

In order to maximize the solderable shelf life of these products, PennEngineering® recommends the following:

  • Product should remain in original packaging (with desiccant) or equivalent repackaging supplied by an authorized distributor.
  • Storage temperature should be maintained between 5 and 40 °C (41 to 104 °F)
  • Relative humidity should not exceed 80%
