SOLDERING PROFILE FINAL PACKINGIR Reflow Soldering Profile for Lead (Pb)-free Soldering The sealed reel is packed into a cardboard box. A secondary Preconditioning acc. to JEDEC level 3 cardboard box is used for shipping purposes. 300 max. 260 °C 255 °C
RECOMMENDED METHOD OF STORAGE250 245 °C 240 °C Dry box storage is recommended as soon as the aluminum 217 °C 200 bag has been opened to prevent moisture absorption. The max. 30 s following conditions should be observed, if dry boxes are 150 not available: max. 120 s max. 100 s Temperature (°C) 100 • Storage temperature 10 °C to 30 °C • Storage humidity ≤ 60 % RH max. 50 max. ramp up 3 °C/s max. ramp down 6 °C/s After more than 168 h under these conditions moisture 0 content will be too high for reflow soldering. 0 50 100 150 200 250 300 Time (s) In case of moisture absorption, the devices will recover to 19885-1 max. 2 cycles allowed the former condition by drying under the following condition: Fig. 7 - Vishay Lead (Pb)-free Reflow Soldering Profile (acc. to J-STD-020C) 192 h at 40 °C + 5 °C / - 0 °C and < 5 % RH (dry air / nitrogen) or
