Device handling instructions
TCM 515Z shall be handled according to Moisture Sensitivity Level MSL 3. TCM 515Z may
be soldered only once, since one time is already consumed at production of the module
itself.
Once the dry pack bag is opened, the desired quantity of units should be removed and the
bag resealed within two hours. If the bag is left open longer than 30 minutes the desiccant
should be replaced with dry desiccant. If devices have exceeded the specified floor life time
of 168 h, they may be baked according IPC/JEDEC J-STD-033B at max. 90 °C for less than
60 hours.
Devices packaged in moisture-proof packaging should be stored in ambient conditions not
exceeding temperatures of 40 °C or humidity levels of 90% r.H.
TCM 515Z modules have to be soldered within 6 months after delivery!
In general we recommend a no clean flux process. If washing is needed, then TCM 515Z
radio modules have a shield cover with small openings at the top of the edges.
It is very important to mount the modules in a top down position during the drying process
as this will allow getting the aggregated washing fluid removed properly from within the
shield cover area.
To prevent damage, modules have to be checked for any remaining fluid after the drying.
