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.

APPLICATIONS

High Flexure Stress Circuit Boards

• e.g. Depanelization: Components near edges

of board.

Variable Temperature Applications

• Soft termination offers improved reliability per-

formance in applications where there is tem-

perature variation.

• e.g. All kind of engine sensors: Direct

connection to battery rail.

Automotive Applications

• Improved reliability.

• Excellent mechanical performance and

thermo mechanical performance.

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.

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

• 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

Soft Term - No Defects up to 3000 cycles

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.

• 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

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.
