Technical content

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.

• Created by the Automotive Electronics Council
• Specification defining stress test qualification for passive components Testing: Key tests used to compare soft termination to AEC-Q200 qualification:
• Bend Test
• Temperature Cycle Test 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 Procedure as per AEC-Q200: Sample size: 20 components Span: 90mm Minimum deflection spec: 2 mm
• Components soldered onto FR4 PCB (Figure 1)
• Board connected electrically to the test equipment (Figure 2) Fig 1 - PCB layout with electrical connections Fig 2 - Board Bend test equipment Test Temperature Profile (1 cycle) TABLE SUMMARY
• The board is placed on 2 supports 90mm apart (capacitor side down)
• The row of capacitors is aligned with the load stressing knife
• 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 Max. = 10mm Max. = 10mm 90mm

MLCC with FLEXITERM® Specifications and Test Methods FLEXITERM® TEST SUMMARY 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.

• 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
