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 number is built from part and screening level. The part
number can be extended to include the additional options
as shown below.
Type – See Main Part Number
ESA Quality Level Products are based on the testing
procedures specified in the generic ESCC 5000 and in the
corresponding part detail specifications.
Package Variant – See Mechanical Data
Screening Level – See Screening Options (ESA / JQRS)
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.

Alternative or additional customer specific conformance or
screening requirements would be considered. Contact
Semelab sales with enquires.
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
Parts are typically marked with specification number, serial
number (or week of seal) as shown in the example below.
Example ordering information:
The following example is for the part with, JQRS screening,
additional Group C conformance testing and a Data pack.
Customer specific marking requirements can be arranged at
time of order but is approximately limited to two lines of
7 Characters. This is to ensure text remains readable..
Part Numbers:
2N2857CSM-JQRS (Include quantity for flight parts)
2N2857CSM-JQRS.GRPC (chargeable conformance option)
2N2857CSM-JQRS.GCDE (charge for destructive parts)
2N2857CSM-JQRS.GCDM (charge for destructive parts)
2N2857CSM-JQRS.DA (charge for Data pack)
Example Marking:
Customers with any specific requirements (e.g. marking,
package or screening) may be supplied with a similar
alternative part number (there is maximum 20 character
limit to part numbers). Requirements for deep dielectric
discharge variant (LCC1-4) must be specified at time of
order. Contact Semelab sales with all enquiries
