8 Product testing
8.1 u-blox in-series production test
u-blox focus on high quality for its products. All units produced are fully tested automatically in the
production line. A stringent quality control process has been implemented in the production line.
Defective units are analyzed in detail to improve the production quality.
This is achieved with automatic test equipment (ATE) in the production line, which logs all
production and measurement data. A detailed test report for each unit can be generated from the
system. Figure 18 illustrates the typical automatic test equipment (ATE) in a production line.
The following tests are performed as part of the production tests:
• Digital self-test (software download, MAC address programming)
• Measurement of voltages and currents
• Functional tests
• Digital I/O tests
• Measurement of RF characteristics in all supported bands (such as receiver RSSI calibration,
frequency tuning of the reference clock, calibration of transmitter power levels and so on.)

8.2 OEM manufacturer production test
As the testing is already performed by u-blox, an OEM manufacturer does not need to repeat
software tests or measurement of the module’s RF performance or tests over analog and digital
interfaces in their production test.
However, an OEM manufacturer should focus on:
• Module assembly on the device; it should be verified that:
o Soldering and handling processes have not damaged the module components
o All module pins are well soldered on the device board
o There are no short circuits between pins
• Component assembly on the device; it should be verified that:
o Communication with host controller can be established
o The interfaces between the module and device are working
o Overall RF performance test of the device including the antenna
