4.3 Patch WIFI modules installed before the notice:
\
WIFI module installed note:
\
1. Please press 1 : 1 and then expand outward proportion to 0.7 mm, 0.12 mm thickness When open a stencil
\
2. Take and use the WIFI module, please insure the electrostatic protective measures.
\
3. Reflow soldering temperature should be according to the customer the main size of the products, such as the temperature set at 250 + 5 ¡É for the MID motherboard.
\
\
About the module packaging, storage and use of matters needing attention are as follows:
\
1. The module of the reel and storage life of vacuum packing: 1). Shelf life: 8 months, storage environment conditions: temperature in: < 40 ¡É, relative humidity: < 90%RH.
\
2. The module vacuum packing once opened, time limit of the assembly:
\
1) check the humidity display value should be less than 30% (in blue), such as: 30% ~ 40% (pink), or greater than 40% (red) the module have been moisture absorption.
\
2) factory environmental temperature humidity control: ? -30 ¡É, ? 60% RH.
\
3) Once opened, the workshop the preservation of life for 168 hours.
\
3. Once opened, such as when not used up within 168 hours:
\
1) The module must be again to remove the module moisture absorption.
\
2) The baking temperature: 125 ¡É, 8 hours.
\
3) After baking, put the right amount of desiccant to seal packages.
