OEM manufacturer production test
As all u-blox products undergo thorough in-series production testing prior to delivery, OEM
manufacturers do not need to repeat any firmware tests or measurements that might otherwise be
necessary to confirm RF performance. Testing over analog and digital interfaces is also unnecessary
during an OEM production test.
OEM manufacturer testing should ideally focus on:
•
Module assembly on the device; it should be verified that:
o
Soldering and handling process did not damage the module components
o
All module pins are well soldered on 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 module and device are working
o
Overall RF performance test of the device including antenna
In addition to this testing, OEMs can also perform other dedicated tests to check the device. For
example, the measurement of module current consumption in a specified operating state can identify
a short circuit if the test result deviates that from that taken against
a “Golden Device”.
The standard operational module firmware and test software on the host can be used to perform
functional tests (communication with the host controller, check interfaces) and perform basic RF
performance testing. Special manufacturing firmware can also be used to perform more advanced RF
performance tests.
