Oscillation Frequency: 10 to 55 to 10Hz for 1min
Amplitude: 1.5mm
Appearance: No damage
∆L ≤ 5%
Time: 2hrs for each axis (X, Y &Z), total 6hrs
∆Q ≤ 10%
Resistance to
Solder Temperature: 260 5ꢀ°
Immersion Time: 10 2sec
Soldering Heat:
Component Adhesion:
1 lbs. For 0402
2 lbs. For 0603
3 lbs. For the rest
The device should be REFLOW soldered
(230 5ꢀ° for 10 seconds) to a tinned copper
substrate. A dynamiter force gauge should be
applied to the side of the component. The device
must with stand a minimum force of 2 or 4
pounds without a failure of the termination
attached to component.
(Push Test)
Drop Test:
After test, there shall be no
evidence of electrical or
mechanical damage
Drop once for each face and once for each
corner. Total drop 10 Times.
Drop height :100cm
Drop weight:125g
Solderability Test:
The terminal should at least be
90% covered with solder.
After fluxing (alpha 100 or equiv), inductor shall
be dipped in a melted solder bath at 260 5ꢀ°
for 5 seconds.
Resistance to Solvent Test:
There shall be no case of
deformation change in
appearance or obliteration of
marking
