1 Introduction
UM980 is a new generation of GNSS high precision RTK positioning module from Unicore. It supports all constellations and all frequencies, and can simultaneously track GPS, BDS, GLONASS, Galileo, QZSS, NavIC and SBAS. The module is mainly used in surveying and mapping, precise agriculture, UAVs, and autonomous robots. UM980 is based on NebulasIVTM, a GNSS SoC which integrates the RF-baseband and high precision algorithm. Besides, the SoC integrates a dual-core CPU, a high speed floating point processor and an RTK co-processor with 22 nm low power design, and it supports 1408 super channels. All these above enable stronger signal processing. With the built-in JamShield adaptive anti-jamming technology, UM980 can fulfill a strengthening RTK engine solution of multi-mode multi-frequency, which ensures a good performance on RTK initialization speed, measurement accuracy and reliability even in the most challenging environments such as urban canyons and tree shades. Furthermore, UM980 supports abundant interfaces such as UART, I2C*, SPI*, as well as 1PPS, EVENT, CAN*, which meets the customers’ needs in different applications.

3.2 Antenna Feed Design
UM980 just supports feeding the antenna from the outside of the module rather than from the inside. It is recommended to use devices with high power and that can withstand high voltage. Gas discharge tube, varistor, TVS tube and other high-power protective devices may also be used in the power supply circuit to further protect the module from lightning strike and surge.
14
If the antenna feed supply ANT_BIAS and the module’s main supply VCC use the same power rail, the ESD, surge and overvoltage from the antenna will have an effect on VCC, which may cause damage to the module. Therefore, it is recommended to design an independent power rail for the ANT_BIAS to reduce the possibility of module damage.

3.3 Power-on and Power-off
VCC The VCC initial level when power-on should be less than 0.4 V. The VCC ramp when power-on should be monotonic, without plateaus. The voltages of undershoot and ringing should be within 5% VCC. Power-on time interval: The time interval between the power-off (VCC < 0.4 V) to
the next power-on must be larger than 500 ms. V_BCKP The V_BCKP initial level when power-on should be less than 0.4 V. The V_BCKP ramp when power-on should be monotonic, without plateaus. The voltages of undershoot and ringing should be within 5% V_BCKP. Power-on time interval: The time interval between the power-off (V_BCKP < 0.4 V)
to the next power-on must be larger than 500 ms.

Notes:
Figure 3-4 Recommended PCB Package Design
For the convenience of testing, the soldering pads of the pins are designed long, exceeding the module border much more. For example:
The pads denoted as detail C are 1.79 mm longer than the module border.
The pad denoted as detail A is 0.50 mm longer than the module border. It is relatively short as it is an RF pin pad, so we hope the trace on the surface is as short as possible to reduce the impact of external interference on the RF signals.

In order to prevent falling off during soldering of the module, do not solder it on the back of the board during design, and it is not recommended to go through soldering cycle twice.
The setting of soldering temperature depends on many factors of the factory, such as board type, solder paste type, solder paste thickness etc. Please also refer to the relevant IPC standards and indicators of solder paste.
Since the lead soldering temperature is relatively low, if using this method, please give priority to other components on the board.
The opening of the stencil needs to meet your design requirement and comply with the examine standards. The thickness of the stencil is recommended to be 0.15mm.

The UM980 module uses carrier tape and reel (suitable for mainstream surface mount devices), packaged in vacuum-sealed aluminum foil antistatic bags, with a desiccant inside to prevent moisture. When using reflow soldering process to solder modules, please strictly comply with IPC standard to conduct temperature and humidity control on the modules. As packaging materials such as the carrier tape can only withstand the temperature of 55 degrees Celsius, modules shall be removed from the package during baking.

Note: 1. The cumulative tolerance of 10 side holes should not exceed ±0.2 mm. 2. Material of the tape: Black antistatic PS (surface impedance 105-1011)
(surface static voltage <100 V), thickness: 0.35 mm. 3. Total length of the 13-inch reel package: 6.816 m (Length of the first part of
empty packets: 0.408 m, length of packets containing modules: 6 m, length of the last part of empty packets: 0.408 m). 4. Total number of packets in the 13-inch reel package: 284 (Number of the first part of empty packets: 17; actual number of modules in the packets: 250; number of the last part of empty packets: 17). 5. All dimension designs are in accordance with EIA-481-C-2003. 6. The maximum bending degree of the carrier tape within the length of 250 mm should not exceed 1 mm (see the figure below).

Before surface mounting, make sure that the color of the 30% circle on the HUMIDITY INDICATOR is blue (see Figure 5-4). If the color of the 20% circle is pink and the color of the 30% circle is lavender (see Figure 5-5), you must bake the module until it turns to blue. The UM980 is rated at MSL level 3. Please refer to the IPC/JEDEC J-STD-033 standards for the package and operation requirements. You may also access to the website www.jedec.org to get more information.
