EMW3080V2
▪ 6 hours drying for module if the color ring at 30%, 40% in humidity indicator card is pink after
unpacking;
▪ 12 hours drying for module if the color ring at 30%, 40%, 50% in humidity indicator card is pink after
unpacking.
⚫ Drying parameters:
▪ Drying temperature: 125℃±5℃；
▪ Alarm temperature: 130℃；
▪ SMT patch when the device cool down below 36℃ in natural condition;
▪ Dry times: 1;
▪ Please dry again if the module is unsoldering in 12 hours after last drying.
⚫ SMT is unsuitable if the module packed over 3 months. There would be serious oxidation of the pad
because of immersion gold and cause false welding and lack of weld. Mxchip does not assume the
corresponding responsibility;
⚫ ESD protection is required before SMT;
⚫ SMT patch should on the basis of reflow profile diagram, maximum temperature 245℃, reflow profile
diagram is shown in figure 10;
⚫ In order to guarantee the reflow soldering qualification rate, vision and AOI detection should be done in
10% products for the first patch to make sure the rationality of temperature control, device adsorption mode
and position. Detect 5 to 10 sample every hour in the following batch production.
Considerations
⚫ Operator should wear anti-static gloves during producing;
⚫ No more than drying time;
⚫ Any explosive, flammable and corrosive material is not allowed to add in drying;
⚫ Module should be put into oven with high thermotolerant tray. Ventilation should exist between each
module and no direct contact with oven;
⚫ Make sure oven is closed when drying to prevent temperature leaking;
⚫ Reduce opening time or keep closing the door of the oven during drying;
⚫ Use anti-static glove to take out module when its temperature below 36℃ by natural cool down after
drying;
⚫ Make sure no water and dirt in the bottom of the module;
⚫ Temperature and humidity control is level 3 for initial modules. Storage and drying conditions are based
on IPC/JEDEC J-STD-020.
