ISO
Certification - ISO9001
Tracewell is ISO 9001 certification in 1992. To ensure continuing
compliance, in addition to periodic audits by our registrar (UL), we have
internal audit teams, who regularly evaluate our adherence to the systems
required by the ISO standard.
Safety Certification
Tracewell Electronics is registered under the UL Compass Program (File
3137737) for power supplies used in Information Technology equipment (UL
1950), which includes the UL Client Test Data Program. In addition
Tracewell Electronics is CSA Category certified and BABT Product Quality
Assurance approved. Our dedicated staff engineer prepares all
documentation submittal packages to UL, CSA, BABT, and TUV Rheinland. We
do NEBS and CB scheme submittals as well. These packages include the
descriptive report, test report and photos.
EMC Testing
Tracewell has established an on-site pre-compliance EMC facility
for the testing of products under development and for the random audit of
production units. The state of the art facility
includes a screen room and a compact 3 meter anechoic chamber. A
dedicated staff member assures consistent
 procedural
test methods with data recording and backup. Testing is under software
control for conducted emissions, radiated emission and surge testing. A
manual test system is employed for ESD compliance testing. Our
engineering staff enjoys a complete complement of troubleshooting tools
for use investigating emissions. These tools include a variety of probes
for use with a selection of network and spectrum analyzers.
Reliability
Tracewell Electronics’ engineering staff routinely performs design
MTBF calculations to either Mil handbook or Bellcore. Where appropriate,
commercial data is used in the calculation. In agreement with customers,
samples of production units are subjected to ongoing reliability tests
(ORT) to detect any latent defects in an accelerated temperature burn-in.
Where selected products have been traceable field MTBF numbers have been
achieved well in excess of 1,000,000 hours.
Data Collection
Several reporting mechanisms have been developed throughout our
organization to collect, store, evaluate, and disseminate data information
from the design phase through end-of-life manufacturing.
Process databases collect data
from throughout the manufacturing process including board assembly test,
unit first test, burn-in or ESS, unit final test final inspection, and
pack. Repair loops database all repairs at board assembly level and unit
level. Our return goods area databases all repairs on returned product.
These databases provide the ability to query for selected data criteria,
as well as establish Pareto analysis and Cpk studies for
process improvement. A conscious effort is made to improve data
collection. Current efforts include upgrading our returned goods
database, expanding data collection to other inspection points, and
incoming component transformer parameters. |
