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

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.
•
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
•
•
•
•
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
•
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
Test Temperature Profile (1 cycle)

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.
AEC-Q200 specification states
1000 cycles compared to AVX
3000 temperature cycles.
•
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 cycle
WITHOUT SOFT TERMINATION
WITH SOFT TERMINATION
Major fear is of latent board flex failures.
Far superior mechanical performance.
Generally open failure mode beyond
5mm flexure
