3.3 Packaging and solder

WM620 modules are packaged in sealed bags on delivery to guarantee a long shelf life. Package the modules

again in case of opening for any reasons.

If exposed in air for more than 48 hours at conditions not worse than 30°C/60% RH, a baking procedure should

be done before SMT. Or, if the indication card shows humidity greater than 20%, the baking procedure is also

required. The baking should last for at least 24 hours at 90℃.

In order to prevent the product of from being affected with damp, caused by using the SMT way to perform the

furnace welding, in the process of production and use of the costumer, we employ the way of damp-proof

packing, such as Aluminum Foil Bag, desiccating agent, Humidity Indicator Cards, Suck plastic trays, and

vacuolization. As a result the product is kept dry and its life span will be long.

For more storage and SMT information, please refer to 《Neoway modules’ recommendation for SMT and

reflow solder》.
