QUALITY & RELIABILITY
QUALITY ASSURANCE
Accu-P® is based on well established thin-film technology and materials.
The reliability of these thin-film chip capacitors has been studied
intensively for several years. Various measures have been taken
to obtain the high reliability required today by the industry. Quality
assurance policy is based on well established international industry
standards. The reliability of the capacitors is determined by accelerated
testing under the following conditions:
• ON-LINE PROCESS CONTROL
This program forms an integral part of the production cycle and acts
as a feedback system to regulate and control production processes.
The test procedures, which are integrated into the production process,
were developed after long research work and are based on the highly
developed semiconductor industry test procedures and equipment.
These measures help KYOCERA AVX to produce a con- sistent and high
yield line of products.

Accelerated Damp
Heat Steady State
125°C, 2UR, 1000 hours
85°C, 85% RH, UR, 1000 hours.
• FINAL QUALITY INSPECTION
Finished parts are tested for standard electrical parameters and visual/
mechanical characteristics. Each production lot is 100% evaluated
for: capacitance and proof voltage at 2.5 UR. In addition, production is
periodically evaluated for:
Average capacitance with histogram printout for capacitance
distribution;
IR and Breakdown Voltage distribution;
Temperature Coefficient;
Solderability;
Dimensional, mechanical and temperature stability.
