Quality is a Given
Quality is right up there with Motherhood and apple pie as inherently a very good thing. And customers generously assume that their vendors' products are top quality until they learn otherwise. Here's how you can know that there'll be no quality surprises with us.
All Plants ISO-9000 Registered
All of our plants's quality systems are registered to ISO-9001. Our registrar is Perry Johnson Registrars. The quality systems are audited twice per year, and we have been registered to ISO-9001 since 1996. We are committed to continuing our ongoing registration to ISO-9001.
Backed by World Class and Military Systems
With more than 40 years experience as a military capacitor supplier we are a QPL supplier for Aluminum Electrolytic MIL-PRF-39018 /01, /03, /04, /06 & /10 products, Mica MIL-C-5 and MIL-PRF-39001, and Wet Tantalum MIL-PRF-39006 /79 & /81 products. We benchmark our component quality with world class systems using:
- Quality System IAW with MIL-STD-790
- Capacitor conformance testing IAW MIL-STD-202
- Standard Practices IAW MIL-STD-790
- Capacitor reliability predictions IAW MIL-HDBK-217
- Assessment of Nonconforming Levels IAW EIA-554
- Statistical Process Controls IAW EIA-557
- Shelf life & Reforming IAW MIL-STD-1131
- Failure rate sampling IAW MIL-STD-690
- Sampling plans IAW ANSI Z1.4
- Calibration IAW ANSI Z540
- Expected Wear-Out Lifetime testing IAW EIA/IS-749
Preproduction Assures It's the Right Part
The quality systems are pegged to the components before, during and after production. Preproduction focuses on design modeling and verification systems. All customer drawings and purchase order requirements are matched to factory bills of material and bills of operation. Ion chromatograph analysis is performed on incoming materials. Maintenance program testing, process audits and comprehensive training programs assure system integrity.
Production Assures It's Built Right
During manufacture online production lot tracking systems maintain a constant record of every part in each production lot. The computer record shows the quality acceptance criteria, inspections, and results for every process step. Designed for reliability, the manufacturing process includes infant mortality elimination steps like CDE's proprietary hot-surge and hot-DCL screens. Process control includes the latest SPC and Cpk sampling and AOQL reporting.
Post-Production Records the Successes
The post-production system assures that the data satisfies you. An AQL sample from every production lot is tested and inspected by Quality Assurance. An AOQL record is maintained of the average outgoing quality level. Data furnished to you can include bar coding, conformance test results, C of C, C of A, 1st article conformance. And, of course, 100% good parts per the customer drawing and purchase order.
Complete Test Lab Certified Per MIL-STD-790
Able to perform all but the most esoteric environmental tests, our test lab is fully equipped for:
- AC ripple current life tests
- Barometric pressure (high altitude) tests
- Cold immersion tests
- DC life tests
- Dielectric Withstanding Voltage Test
- Flammability Test
- Hot immersion tests
- Impact shock tests
- Insulation Resistance Test
- Marking Permanency test
- Moisture resistance tests
- Reverse voltage aging test
- Salt environment tests
- Safety vent tests
- Seal tests
- Shelf life tests
- Solderability Test
- Solvent resistance tests
- Temperature cycling tests
- Terminal Strength Test
- Thermal shock tests
- Vent Test
- Vibration tests, low and high frequency
- Weight Loss Test
- X-Ray Inspection
The lab typically has 8 to 12 thousand capacitors on test, can perform over 100 different types of mechanical and chemical tests and is certified per MIL-STD-790.
Beyond qualification data, the lab can furnish downright useful application performance data. As an illustration, for ripple current capability we can measure the core temperature rise, the ESR at any frequency, and we can perform ripple current life tests per EIA-IS-749 that tests the capacitors lying down in a horizontal position. That's shown to be a more severe test and representative of many customer applications.
