Device and method for testing PCBAof smart watch

Abstract

The invention discloses a device and method for testing PCBA (Printed Circuit Board Assembly) of a smart watch, and the device comprises a testing frame (1), the testing frame (1) is provided with a testing jig, the testing jig comprises a top plate (2) and a bottom plate (13), the bottom plate (13) is fixedly disposed on the testing frame (1), the testing frame (1) is internally provided with an installation cavity, the installation cavity is covered by the bottom plate (13), the installation cavity is internally provided with a PCB (3), the PCB (3) is provided with an ejector pin (17), a test bottom plate power supply switch, a test bottom plate battery charging switch, a main control chip (16), a communication interface (5), a serial port (8), a voltage detection interface (11), a firmware burning interface (10), an I2C expansion interface (6) and a switch interface (7). The device is easy to operate and high in efficiency.

Description

technical field

[0001] The invention relates to the field of smart watch testing, in particular to a smart watch PCBA testing device and method. Background technique

[0002] The smart watch PCBA test generally requires the support of the test fixture. By programming the test fixture bottom plate, driving the screen display, buttons, LCD, etc., the control and display of the test PCBA by the test fixture bottom plate is realized. Because the test baseboard is controlled by a single-chip microcomputer, programming is difficult and takes a long time, and it is inconvenient to modify and has poor flexibility. After the test fixture obtains the PCBA parameters, because it is impossible to flexibly set the parameters of different devices and different batches, the test fixture cannot automatically judge whether it is passed or not. It requires workers to press buttons to feedback and judge. Workers need to monitor the test progress all the time. One worker can only operate one T...
