Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

In the production process of electronic products, a series of tests are usually performed on a production line before the electronic products can be put on the market for sale. The length of the test time is related to the production cost, the comprehensiveness of the test is related to the product quality, and the product quality seriously affects the market public praise and the after-sale cost, so the test is very important before the electronic products are released.

One important component of electronic products is a Printed Circuit Board (PCBA) with communication function, which is manufactured by a Printed Circuit Board Assembly (PCBA) process, so that the circuit board and a finished product packaged with the circuit board need to be tested before the electronic products are put into service. When the circuit board and the finished product are tested, the circuit board and the finished product are tested by using the test firmware, and after the test is finished, formal firmware is required in the finished product for normal use of the finished product.

In the prior art, a test mode is generally performed on formal firmware, a test mode is entered through special operations during production, and a production worker completes a test on a product in the test mode and records a result. In addition, a test firmware is separately manufactured, the test firmware is burned in production, the test fixture sends a test command through a wired connection mode (such as a serial port), the equipment returns a test result, and the formal firmware is burned in after the test is finished.

However, the method of including the test mode in the formal firmware has an obvious disadvantage of occupying program space, often requiring a chip with larger program space, and invisibly increasing hardware cost; moreover, the production cost is greatly burdened by using a manual test mode, obvious flaws exist in manual judgment, workers are not careful, the conditions of missed detection and false detection can be caused by recording errors and the like, and the test data is inconvenient to summarize and count. The method of wired test and secondary burning is only suitable for equipment with reserved communication interfaces, for products with higher waterproof requirement level or requirements for attractive appearance, the communication interfaces are difficult to reserve for testing and firmware upgrading, and the secondary burning can also reduce the efficiency of the testing process.

Based on the above analysis, the embodiment of the present application provides a circuit board testing system and a finished product testing system, where the circuit board testing system is used for testing a circuit board to be tested, and the finished product testing system is used for testing a finished product to be tested.

Step S402: the control module obtains the MAC address of the circuit board to be tested.

Step S403: the server receives the MAC address of the circuit board to be tested and allocates a unique serial number to be pre-bound with the circuit board to be tested.

Step S407: and the base station receives the MAC address and the unique serial number, is connected with the circuit board to be tested according to the MAC address, and sends the MAC address and the unique serial number to the circuit board to be tested.

Step S408: and the circuit board to be tested receives the MAC address and the unique serial number, stores the unique serial number and sends confirmation information representing successful connection between the base station and the circuit board to be tested to the control module.

Specifically, first, the server may generate a preset number of unique serial numbers, each of which should be different from the others. The preset number may be a number required by an order, a number of circuit boards to be detected, or a predetermined number, for example: 100, etc., and the embodiments of the present application are not particularly limited thereto, and those skilled in the art can make appropriate adjustments according to the circumstances.
