NJL5901R - 6 - precaution for handling 1. soldering to actual circuit board soldering condition the surface temperature of plastic package is lower than 260 c. soldering method 1) reflow method soldering to be done within twice under the recommended condition mentioned below 2) reflow method (in case of infrared heating) the temperature profile is same as the above avoid direct irradiation to the pl astic package because it ma y absorb the infrared radiation and its surface temperature will be higher than the lead. 3) the other method avoid rapid heating up like dipping the devices directly into the melting solder or vapor phase method (vps). solder the device in short time as soon as possible. if the device is heated and kept in high temperature for longer time, its reliability would be affected. 2. cleaning avoid washing the device after soldering by reflow method. 3. attention in handling 1) treat not to touch the lens surface. 2) avoid dust and any other foreign materials on the lens surface such as paint, bonding material, etc. 4. storage mount the device as soon as possible after opening the envelope. in order to prevent from degradation by the moisture at the reflow process, the device is contained in deaeration packaging. a b c g e 150 c 260 c room te m p . f 180 c 230 c 220 c d a : temperature ramping rate : 1 to 4 c/s b : pre-heating temperature time : 150 to 180 c : 60 to 120s c : temperature ramping rate : 1 to 4 c /s d : 220 c or higher time : shorter than 60s e : 230 c or higher time : shorter than 40s f : peak temperature : lower than 260 c g : temperature ramping rate : 1 to 6 c /s the temperature of the surface of mold package
