The unit cannot be mounted arbitrary, because of the radio communication. The unit with an internal surface mounted antenna
(cB-OBS411i and cB-OBS411j) cannot be mounted in a metal enclosure. No metal casing or plastics using metal flakes should be used,
avoid also metallic based paint or lacquer. Keep a minimum clearance of 5 mm between the antenna and the casing. Keep minimum 10
mm free space from metal around the antenna including under and above. If a metal enclosure is required, one of the external antenna
options has to be used. See
6.5 Antenna Issues
The modules are produced in a lead-free process with a lead-free soldering paste.
It is recommended that the customers make their own electrical, climate, stress and vibration tests on the final assembled
product to secure that the manufacturing process hasn't damaged or affected the Bluetooth module in any way.
The modules are normally delivered without labels on each module when packaged on tape-and-reel. However, if they are
delivered with labels on each module, the labels should be removed before the module is processed since the labels do not
withstand the heat of soldering.
Modules delivered on trays are classed with MSL-Class 3.
The device recommended maximum re-flow temperature is 245°C for 10 sec.
The device absolute maximum re-flow temperature is 250°C for 3 sec.
