Resistors
Put the specimens on the test fixture and two
△R=±3.0%
(2)discharges (3KVDC) shall be applied to each PUT,
one (1) with a positive polarity and one (1) with a negative
polarity. Afterwards, the specimens stabilize for 30min or
more and measure of its resistance variance rate. The
test is performed with direct contact and regular
discharge mode. The resistor and capacitor used on the
spearhead is 2000Ω and 150pF respectively.
ESD
Experiment evidence AEC-Q200
Test method:
Test item 1 (solder pot test): Method B
Precondition:
1. Soldering coverage over 95%
2. At the edge of terminal, the object
underneath (e.g. white ceramic) shall
not expose.
The specimens are subjected to 155℃ dry bake for
4hrs±15min.
The specimens are immersed into the flux first, then fully
immersed into the solder pot, at a temperature of
235± 5℃ for 5+0/-0.5 sec. Then rinse with water and
observe the soldering coverage under the microscope.
Test item 2 (Leaching test): Method D
The specimens are immersed into the flux first, then fully
immersed into the solder pot, at a temperature of
260±5℃ for 30+0/-0.5 sec. Then rinse with water and
observe the soldering coverage under the microscope.

Solder the specimens on the test PCB and put the PCBA △R=±1.0%
onto the Bending Tester. Add force at the central part of
PCB, and the duration of the applied forces shall be
60 (+ 5) Sec. Measure of its resistance variance rate in
load.
