NOTES:
Test should be made under the conditions of room temperature (20±10℃), normal humidity (60±20%) and normal
atmospheric pressure. In this case, however, that the judgment is questionable, the test conditions are to be changed to room
temperature 20±2℃, relative humidity 60~70% and normal atmospheric pressure

Drop test
Drop a product naturally from the height of 700mm onto the
surface of 100mm thick wooden board. Two directions: upper
and side of the product are to be applied for this drop test once
respectively
Reflow soldering
heat resistance
a)
Pre-heating conditions shall be +140℃ to 160℃ for 160
to 200 seconds. (See Figure5-9)
b)
Heating conditions shall be within 60 seconds at +200℃
min., but peak temperature shall be lower than +260℃. (See
Figure 5-9)
Test of soldering
Dip the connecting pins in soldering at 255±5℃ for 3±0.5
seconds
Solder shall be
attached around over
95% of the dipped
portion
NOTE: The pins are allowed to deform after drop test.
