Production Testing

Overview

The purpose of the test procedure is to identify connectivity issues, poor soldering, and potential manufacturing defects. Some of the issues are directly identified by explicit part-targeted tests, others are implicit, by running adjacent tests.

There is only one test fixture that will be used to test three different hardware platforms:

Jupiter Main Board
Jupiter Add-on Board
Jupiter System

Once the initial setup for one of the hardware platforms is done, it is highly recommended that all the hardware platforms of the same type be tested before changing the setup to test another hardware platform. It is mandatory to run the Main Board and Add-on Board tests before System testing because the Jupiter System should include only boards that previously passed the manufacturing testing.

Labeling

The label stuck on the boards will be scanned during testing and the information will be stored into the board’s EEPROM. Also, the test logs will contain the info on the labels so that we can track the logs.

The label stuck on the enclosure will allow us to identify the hardware our customer is referring to and we can always check the testing logs to check how the device was performing during testing.

Test Sequence 1 - Main Board Test

Main Board Labeling

The label contains the board ID and its QR code:

Manufacturing Date in the format yyyymmdd
Board ID: a 5 digit decimal number

The label will be printed by the manufacturing company on their available printer. The label needs to be stuck to the PCB before production testing since it needs to be scanned during testing.

Label size: 13.81 x 6.35 mm

Example: 2023110600018

3	Connect External Reference clock cable and MCS cable (CLK OUT and MCS OUT) to SMA connectors of the DUT board
4	Before testing another board, or at the work day end, make sure to remove all the cables from the DUT
5	After disconnecting the DUT, place a new one and repeat testing steps 2 and 3

Replug cable but rotated 180 degrees:

After the test suite passed, a green “PASSED” message will appear on the screen.

When at least one test is failing, at the end of the test suite a “FAILED” message will be displayed.

Note

In case a failure occurred, a “FAILED” message will be displayed and you will be prompted to enter a new command.

If at any point a test fails, you are prompted with a message saying: “Do you want to repeat test?”. In case the test failed due to an unconnected cable, or some exceptional reason, you can opt to repeat the last test as shown below:

Alternatively, if you realize that there is something wrong with the board and you do not wish to continue with the rest of the procedure, you can press “n” + “ENTER” and stop the test, which will also prompt a test failure:

2) Add-on Test

Type “2” into the terminal and press ENTER to start 2) Add-ON test.

In case a failure occurred, a “FAILED” message will be displayed.

After the test is passed, a green “PASSED” message will appear on the screen.

3) System Test
