SCREENING OPTIONS

Space Level (JQRS/ESA) and High Reliability options are

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. 22A.

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..
