What type of Reliability tests are important and recommended to assess packaging and plating reliability for 100% matte tin?
Recommended Reliability Tests are: IR or Convection reflow at 260°C peak temperature with preconditioning. 85/85, HAST, Pressure Pot (Autoclave), High Temperature Storage, DHTL. Temperature cycling with IR or convection reflow as precondition. Solderability testing with and without aging. Note that package preconditioning would depend on the Moisture Level rating of the package and materials used in lead-free assembly.
