Automotive MLCC with FLEXITERM® Datasheet

MLCC with FLEXITERM®
General Specifications
GENERAL DESCRIPTION
With increased requirements from the automotive industry for additional
component robustness, AVX recognized the need to produce a MLCC with
enhanced mechanical strength. It was noted that many components may be
subject to severe flexing and vibration when used in various under the hood
automotive and other harsh environment applications.
To satisfy the requirement for enhanced mechanical strength, AVX had to
find a way of ensuring electrical integrity is maintained whilst external forces
are being applied to the component. It was found that the structure of the
termination needed to be flexible and after much research and development,
AVX launched FLEXITERM ® . FLEXITERM ® is designed to enhance the
mechanical flexure and temperature cycling performance of a standard
ceramic capacitor with an X7R dielectric. The industry standard for
flexure is 2mm minimum. Using FLEXITERM®, AVX provides up to
5mm of flexure without internal cracks. Beyond 5mm, the capacitor
will generally fail “open”.
As well as for automotive applications FLEXITERM® will provide Design
Engineers with a satisfactory solution when designing PCB’s which may be
subject to high levels of board flexure.
PRODUCT ADVANTAGES
• High mechanical performance able to withstand, 5mm bend test
guaranteed.
• Increased temperature cycling performance, 3000 cycles and beyond.
• Flexible termination system.
• Reduction in circuit board flex failures.
• Base metal electrode system.
• Automotive or commercial grade products available.
APPLICATIONS
High Flexure Stress Circuit Boards
• e.g. Depanelization: Components near edges
of board.
Variable Temperature Applications
• Soft termination offers improved reliability performance in applications where there is temperature variation.
• e.g. All kind of engine sensors: Direct
connection to battery rail.
Automotive Applications
• Improved reliability.
• Excellent mechanical performance and
thermo mechanical performance.

TEMPERATURE CYCLE TEST PROCEDURE
Test Procedure as per AEC-Q200:
The test is conducted to determine the resistance of the
component when it is exposed to extremes of alternating
high and low temperatures.
• Sample lot size quantity 77 pieces
• TC chamber cycle from -55ºC to +125ºC for 1000 cycles
• Interim electrical measurements at 250, 500, 1000 cycles
• Measure parameter capacitance dissipation factor,
insulation resistance
Test Temperature Profile (1 cycle)
+1250 C
• The board is placed on 2 supports 90mm
apart (capacitor side down)
• The row of capacitors is aligned with the
load stressing knife
Max. = 10mm
• The load is applied and the deflection where
the part starts to crack is recorded (Note:
Equipment detects the start of the crack
using a highly sensitive current detection
circuit)
• The maximum deflection capability is 10mm
+250 C

FLEXITERM® TEST SUMMARY
• Qualified to AEC-Q200 test/specification with the exception
of using AVX 3000 temperature cycles (up to +150°C bend
test guaranteed greater than 5mm).
• FLEXITERM® provides improved performance compared to
standard termination systems.
WITHOUT SOFT TERMINATION
Major fear is of latent board flex failures.
62
• Board bend test improvement by a factor of 2 to 4 times.
• Temperature Cycling:
– 0% Failure up to 3000 cycles
– No ESR change up to 3000 cycles
WITH SOFT TERMINATION
Far superior mechanical performance.
Generally open failure mode beyond
5mm flexure.
