12. Wireless module before the SMT note:
1.When the customer makes the steel mesh, ensure that the hole is larger than the size of the wifi module
pad,please press 1 to 1 and 0.7 mm is widened to open outward, the thickness of 0.12 mm.
2.Can't get the wifi module bare hands when needs,must we wear the gloves and static ring.
3.The furnace temperature according to the size of the customer the mainboard ,generally like to stick on a
tablet standard temperature of 245±5℃
4.Storage and use wifi module control should pay attention to the following matters:
Module of the storage life of vacuum packaging:
4.1.1.Storage life:12 months.Storage conditions:<40℃.Relative humidity:<90%R.H.
4-2.After this bag is opened,devices that will be subjected to infrared reflow,vapor-phase reflow,or
equivalent processing must be:
4-3.Check the humidity card :
stored at≦20%RH.If :30%~40%(pink)or greater than 40%(red),module has moisture absorption.
① Mounthed within 168 hours at factory
conditions of:t≦30%℃,≦60%RH.
② Once opened,the workshop the preservation of life for 168 hours.
4-4.If baking is required,devices may be baked for:
① Modules must be to remove module moisture problem.
② Baking temperature:50℃,72hours.
③ After baking,put proper amount of desiccant to seal packages.
4-5.The actual number of module vacuum packing which is based on the actual number of packages to the
customer requirements.
5.Module reel packaging items as follows.
5-1.Storage life:12 months.Storage conditions:<40℃.Relative humidity:<90%R.H.
5-2.Module apart packing after 168 hours,to launch patch need to bake,to remove the module hygroscopic.
Baking temperature conditions:50℃,72 hours.
5-3. The actual number of module reel packing which is based on the actual number of packages to the
customer requirements.
