These are recommendations only and not specifications. The exact mask geometries,
distances, and stencil thicknesses must be adapted to the specific production processes of the
customer.

Thermal guidelines
The NINA-B1 series modules have been successfully tested in -40 °C to +85 °C. The NINA-B1 series module is a
low power device and will generate only a small amount of heat during operation. A good grounding should still
be observed for temperature relief during high ambient temperature.
3.9
ESD guidelines
The immunity of devices integrating NINA-B1 modules to Electro-Static Discharge (ESD) is part of the
Electro-Magnetic Compatibility (EMC) conformity, which is required for products bearing the CE marking,
compliant with the R&TTE Directive (99/5/EC), the EMC Directive (89/336/EEC) and the Low Voltage Directive
(73/23/EEC) issued by the Commission of the European Community.
Compliance with these directives implies conformity to the following European Norms for device ESD immunity:
ESD testing standard
CENELEC EN 61000-4-2
and the radio equipment standards
ETSI EN 301 489-1
,
ETSI EN
301 489-7
,
ETSI EN 301 489-24
, the requirements of which are summarized in Table 10.
The ESD immunity test is performed at the enclosure port, defined by
ETSI EN 301 489-1
as the physical
boundary through which the electromagnetic field radiates. If the device implements an integral antenna, the
enclosure port is seen as all insulating and conductive surfaces housing the device. If the device implements a
removable antenna, the antenna port can be separated from the enclosure port. The antenna port includes the
antenna element and its interconnecting cable surfaces.
The applicability of ESD immunity test to the whole device depends on the device classification as defined by
ETSI
EN 301 489-1
. Applicability of ESD immunity test to the related device ports or the related interconnecting
cables to auxiliary equipment, depends on device accessible interfaces and manufacturer requirements, as
defined by
ETSI EN 301 489-1
.
Contact discharges are performed at conductive surfaces, while air discharges are performed at insulating
surfaces. Indirect contact discharges are performed on the measurement setup horizontal and vertical coupling
planes as defined in
CENELEC EN 61000-4-2
.
For the definition of integral antenna, removable antenna, antenna port, device classification refer to the
ETSI EN 301 489-1
. For the contact and air discharges definitions refer to
CENELEC EN 61000-4-2
.

NINA-B1 is manufactured taking into account specific standards to minimize the occurrence of ESD events; the
highly automated process complies with IEC61340-5-1 (STM5.2-1999 Class M1 devices) standard thus the
designer should implement proper measures to protect from ESD events, any pin that may be exposed to the
end user.
Compliance with standard protection level specified in EN61000-4-2 can be achieved by including ESD
protections in parallel to the line, close to areas accessible by the end user.
