PROCEDURE
Bend Test
The capacitor is soldered to the printed circuit
board as shown and is bent up to 10mm at
1mm per second:

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

90mm
• 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
