Solder the capacitor to the test jig (glass epoxy board).
The capacitor should be subjected to a simple harmonic motion
having a total amplitude of 1.5mm, the frequency being varied
uniformly between the approximate limits of 10 and 55Hz. The
frequency range, from 10 to 55Hz and return to 10Hz, should be
traversed in approximately 1 min. This motion should be applied
for a period of 2 hrs. in each of 3 mutually perpendicular
directions (total of 6 hrs.).
Solder the capacitor to the testing jig (glass epoxy board) shown
in Fig. 2.
Then apply a force in the direction shown in Fig. 3. The soldering
should be done using the reflow method and should be
conducted with care so that the soldering is uniform and free of
defects such as heat shock.
Immerse the capacitor in a solution of ethanol (JIS-K-8101) and
rosin (JIS-K-5902) (25% rosin in weight proportion).
Immerse in solder solution for 2T0.5 sec.
Immersing speed: 25T2.5mm/s
Temp. of solder: 245T5 C Lead Free Solder (Sn-3.0Ag-0.5Cu)
#Immersing speed: 25T2.5mm/s
#Pretreatment for X7R char.
*Preheating
Preheat the capacitor as in table. Immerse the capacitor in
solder solution at 260T5D for 10T1 sec. Let sit at room
condition*
Perform a heat treatment at 150
let sit for 24T2 hrs. at room condition.*
