SCREENING OPTIONS
Space Level (JQRS/ESA) and High Reliability options are available in accordance with the High Reliability and Screening Options Handbook available for download from the from the TT electronics Semelab web site. ESA Quality Level Products are based on the testing procedures specified in the generic ESCC 5000 and in the corresponding part detail specifications. Semelabs QR216 and QR217 processing specifications (JQRS), in conjunction with the companies ISO 9001:2000 approval present a viable alternative to the American MILPRF-19500 space level processing. QR217 (Space Level Quality Conformance) is based on the quality conformance inspection requirements of MIL-PRF19500 groups A (table V), B (table VIa), C (table VII) and also ESA / ESCC 5000 (chart F4) lot validation tests. QR216 (Space Level Screening) is based on the screening requirements of MIL-PRF-19500 (table IV) and also ESA /ESCC 5000 (chart F3). JQRS parts are processed to the device data sheet and screened to QR216 with conformance testing to Q217 groups A and B in accordance with MIL-STD-750 methods and procedures. Additional conformance options are available, for example Pre-Cap Visual Inspection, Buy-Off Visit or Data Packs. These are chargeable and must be specified at the order stage (See Ordering Information). Minimum order quantities may apply. Alternative or additional customer specific conformance or screening requirements would be considered. Contact Semelab sales with enquires.
ORDERING INFORMATION
Part number is built from part and screening level. The part number can be extended to include the additional options as shown below. Type - See Electrical Stability Characteristics Table Package Variant - See Mechanical Data Screening Level - See Screening Options (ESA / JQRS) Additional Options:

Additional Option Notes: 1) All `Additional Options' are chargeable and must be specified at order stage. 2) When Group B,C or LVT is required, additional electrical and mechanical destructive samples must be ordered 3) All destructive samples are marked the same as other production parts unless otherwise requested.
MARKING DETAILS
Screened parts are typically marked with specification number, serial number & week of seal. Customer specific marking requirements can be arranged at time of order
Example ordering information: The following example is for the part with, JQRS screening, additional Group C conformance testing and a Data pack. Part Numbers: 1N6492-DA-JQRS (Include quantity for flight parts) 1N6492-DA-JQRS.GRPC (chargeable conformance option) 1N6492-DA-JQRS.GCDE (charge for destructive parts) 1N6492-DA-JQRS.GCDM (charge for destructive parts) 1N6492-DA-JQRS.DA (charge for Data pack) Customers with any specific requirements (e.g. marking, package or screening) may be supplied with a similar alternative part number.
