Magnetics for high-reliability applications
View the High Reliability data sheet
All Coilcraft engineering and production facilities have received ISO/TS 16949 (Automotive) and ISO 9001:2000 (Quality Management System) certification for the “Design, manufacture, and distribution of
inductive components including SMT and leaded inductors, transformers and assemblies.”
The high reliability components Coilcraft designs and manufactures meet all the same qualifications. These products are subjected to additional testing to ensure their robustness and their ability to
perform in critical applications. Tests are performed in accordance with Coilcraft Procedure CP-SA-10001 Magnetics for High Reliability Applications.
This flowchart outlines
Coilcraft's procedures for testing devices used in medical applications.
High Reliability Quality Assurance Process
The Coilcraft Quality Assurance Process is characterized by the following
criteria:
| • |
Requalification testing performed on samples from each manufacturing lot |
| • |
Lot traceability maintained throughout the manufacturing process and documentation kept on file for a minimum of 20 years |
| • |
100% rated current burn-in testing |
| • |
100% electrical screening |
| • |
100% visual inspection for mechanical properties under 15× magnification minimum |
High Reliability Specifications
A sample of ten pieces from each lot is subjected to solderablilty testing. This
test consists of the following procedure:
| • |
Visual inspection |
| • |
High temperature storage at 125°C for 72 hours
|
| • |
Steam aging at 93°C for one hour |
| • |
Immersion in rosin flux for 5 to 10 seconds
|
| • |
Solder dip |
| • |
Cleaning |
| • |
Visual inspection |
At the completion of the solderability testing, every part of each
manufacturing lot is subjected, at minimum, to the following burn-in tests:
| • |
Thermal shock 10 cycles from –55°C to +155°C
|
| • |
Rated current burn-in for five minutes |
| • |
No-load burn-in for 72 hours at 125°C |
| • |
Visual inspection |
Additional tests, as specified by the customer, can also be conducted. Modifications to the basic tests are also accommodated and incorporated into the test procedure.
At the completion of these tests, a sample of each lot is submitted to Quality Assurance to be incorporated into the accumulated lot for requalification testing. For information regarding critical products availability and pricing, email cp@coilcraft.com, or fax quote requests to 1-847-639-1508. |
