Moisture Sensitivity Level (MSL)
Joint Industry Standard IPC/JEDEC J-STD-020E (Moisture/Reflow Sensitivity Classification for Nonhermetic Surface Mount Devices) does not specify any tests or failure criteria for “Non-IC Packages”, i.e. all products manufactured by Harwin. However, Harwin is confident that all products can be classified as MSL Level 1, if required.
Sensitivity to Electrostatic Discharge (ESD)
No Harwin products are sensitive to Electrostatic Discharge (ESD).
Shelf Life for Harwin products
Harwin operates a Shelf Life policy for all connector products containing plated components. IEC Standard 62435-4: 2018 (Electronic components – Long-term storage of electronic semiconductor devices – Part 4: Storage) defines Long-Term Storage (LTS) as any period of time greater than 1 year, but noting that LTS could also last for decades.
At Harwin, any products that have not been consumed within 2 years of the original date of manufacture are revalidated. This revalidation consists of subjecting test parts to artificially accelerated ageing. The product batch is then acceptable for a further 3 years shelf life.
During the period of the 3 year shelf life, the connectors must be stored in acceptable storage conditions, constituting:
- Product must be kept in the original sealed Harwin packaging at all times, and must retain all date code traceable numbers;
- Product must be stored in a suitable environment that is not subjected to extreme variations of temperature and humidity.
