The Specimen shall be vibrated by its lead wires with a total amplitude of 1.5㎜ and a
varying frequency of 10~55~10HZ(each minutes) for a period of 2 hours respectively in
each X,Yand Z directions.
After dipping the terminal to depth of approximately 3㎜ from the specimen in a
soldering bath of 260℃ for 10±1(D5: 5±1) seconds. Thereafter the terminal shall be
visually examined.
After preheating the specimen, the specimen shall be completely immersed into a
soldering bath having a temperature of 260±5℃ for 10±1 (D5: 5±1) seconds or iron of
