8 Package
WM620 modules are packaged in sealed bags on delivery to guarantee a long shelf life. Follow the same
package method again in case of opened for any reasons.
If the module is exposed to air for more than 48 hours at conditions not worse than 30°C/60% RH, bake it
at a temperature higher than 90 degree for more than 12 hours before SMT. Or, if the indication card
shows humidity greater than 20%, the baking procedure is also required. Do not bake modules with the
package tray directly.
