Visual inspection

-

Immerse the components in solvents

(as per MIL-STD-202 Method 215) for 3

min each (25 °C, or 63 to 70 °C)

Solvents:

a) Isoporpyl alcohol (1 part)

and mineral spirit (3 parts)

b) Terpene defluxer

c) Water (42 parts), propylene

glycol monomethyl ether (1

part) and

monomethanolamine (1

part)

Fix the component on PCB and perform

3 shocks in each direction along the 3

mutually perpendicular axes of the

MLCC (in total 18 shocks), half-sine

puls form, 1500 g peak value, 0.5 ms

duration

∆C/C within ±4.5%

∆C/C within ±7.5% for 25 V

D.F. < 25 · 10-3

D.F. < 50 · 10-3 for 25 V

I.R. > 1 · 105 MΩ or τ > 1000 s resp. 500 s for 25 V

(whichever is less)

Fix the component on PCB and perform

12 cycles in each of the 3 mutually

perpendicular axes of the MLCC (in

total 36 cycles). Subject the MLCC to a

simple harmonic motion variing the

frequency logarithmically between 10

and 2000 Hz and return to 10 Hz

(duration approx. 20 min) with an

amplitude of 1.5 mm
