Wafer Storage Guidelines It is necessary to conform to appropriate wafer storage practices to avoid product degradation or contamination. Wafers may be stored for up to 18 months in the original packaging supplied by Silicon Labs. must be stored at a temperature of 18–24 °C. Wafers must be stored in a humidity-controlled environment with a relative humidity of <30%. Wafers should be stored in a clean, dry, inert atmosphere (e.g. nitrogen or clean, dry air). Wafers 6. Failure Analysis (FA) Guidelines Certain conditions must be met for Silicon Laboratories to perform Failure Analysis on devices sold in wafer form. In order to conduct failure analysis on a device in a customer-provided package, Silicon Laboratories must be provided with die assembled in an industry standard package that is pin compatible with existing packages Silicon Laboratories offers for the device. Initial response time for FA requests that meet this requirements will follow the standard FA guidelines for packaged parts. If retest of the entire wafer is requested, Silicon Laboratories must be provided with the whole wafer. Silicon Laboratories cannot retest any wafers that have been sawed, diced, backgrind or are on tape. Initial response time for FA requests that meet this requirements will be 3 weeks. 16 Rev. 1.1 DOCUMENT CHANGE LIST Revision 0.1 to Revision 0.2 Updated Table 3 on page 11.
