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

AVX ENHANCED SOFT TERMINATION

BEND TEST PROCEDURE

Bend Test

The capacitor is soldered to the printed circuit board as

shown and is bent up to 10mm at 1mm per second:

• 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
