To-and Fri sweep time(from 10 to 55Hz and then 55 to 10) under single amplitude of 0.75mm is 3 minute, then expose to the room temperature for 2 hours 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 230±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.
