SCREENING OPTIONS
ORDERING INFORMATION
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.
Part numbers are built up from Type, Package Variant, and
screening level. The part numbers are extended to include
the additional options as shown below.
Type – See Main Part Type
Package Variant – See Mechanical Data
Screening Level – See Screening Options (ESA / JQRS)
ESA Quality Level Products are based on the testing
procedures specified in the generic ESCC 5000 and in the
corresponding part detail specifications.
Additional Options:
Semelabs QR216 and QR217 processing specifications
(JQRS), in conjunction with the companies ISO 9001:2000
approval present a viable alternative to the American MIL-
PRF-19500 space level processing.

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.
Alternative or additional customer specific conformance or
screening requirements would be considered. Contact
Semelab sales with enquires.
MARKING DETAILS
Example ordering information:
Parts can be laser marked with approximately 7 characters
on two lines and always includes cathode identification.
Typical marking would include part or specification number,
week of seal or serial number subject to available space and
legibility.
The following example is for the 1N6642 part with package
variant A, JQRS screening, additional Group C conformance
testing and a Data pack.
Part Numbers:
1N6642D2A-JQRS (Include quantity for flight parts)
1N6642D2A-JQRS.GRPC (chargeable conformance option)
1N6642D2A-JQRS.GCDE (charge for destructive parts)
1N6642D2A-JQRS.GCDM (charge for destructive parts)
1N6642D2A-JQRS.DA (charge for Data pack)
Customer specific marking requirements can be arranged at
the time of order.
Example Marking:
Customers with any specific requirements (e.g. marking or
screening) may be supplied with a similar alternative part
number (there is maximum 20 character limit to part
numbers). Contact Semelab sales with enquiries
