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 MIL-
PRF-19500 space level processing.
QR217 (Space Level Quality Conformance) is based on the
quality conformance inspection requirements of MIL-PRF-
19500 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.
MARKING DETAILS
Screened parts are typically marked with specification
number, serial number (or week of seal) as shown in the
example below. All non screened parts are printed with
three characters only eg. 92A.
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..
Example Marking:

samples must be ordered
3) All destructive samples are marked the same as other production parts unless
otherwise requested.
Example ordering information:
The following example is for the 4 pad packaged part
option with, JQRS screening, additional Group C
conformance testing and a Data pack.

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 (C1B) must be specified at time of order.
