System, PCBA board and method for achieving PCBA board testing

Abstract

The invention provides a PCBA board used for achieving PCBA board testing. The PCBA board is electrically connected with a display device through a signal connecting line, and the PCBA board is provided with a plurality of functional circuits and at least one programmable chip, and further comprises a CPU and a testing unit. The CPU is used for uploading a test program in a complete system program in advance, the complete system program is an operation system program of a device loading the PCBA board, and the testing unit is used for executing the test program to test the functional circuits and the programmable chip of the PCBA board. The CPU is further used for judging whether the functional circuits and the programmable chip are qualified or not according to the testing results fed back by the functional circuits and the testing result of the programmable chip of the PCBA board, and generating and sending corresponding control signals according to judgment results to trigger the display device to respond to the control signals to display the testing results. The invention further provides a corresponding system and method. According to the PCBA board, the system and the method, the test program is uploaded to the PCBA board in advance to carry out automatic testing and to display testing prompt messages, and therefore the testing speed and testing efficiency of the PCBA board are improved.

Description

technical field [0001] The invention relates to the technical field of chip testing, in particular to a system, a PCBA board and a method for realizing PCBA board testing. Background technique [0002] With the rapid development of electronic industry automation, a large number of various programmable chips were born. PCBA (Printed Circuit Board Assembly) is also a PCB empty board, after SMT (surface mount technology) upper parts, and then through the entire process of DIP plug-in. At present, the detection method of PCBA is still in the manual detection stage. The inspection scheme used by most foundries is as follows: PCBA is first assembled into a complete machine after the SMT process, and then the complete Android firmware is programmed into the PCBA, and sent to the quality inspection department to start the whole machine and perform manual testing step by step according to various functions. If one or several functions are found to be abnormal during the test, the a...

Problems solved by technology

However, using manual work, the inspection speed is slow

And with the update of the Android system, the Android firmware has also become larger and larger. It takes a long time to write all the firmware into the whole machine and enter the detection mode, which seriously affects the production efficiency.

Furthermore, due to the complexity of the Android system, a complete Android machine may contain multiple functional modules, and the entire testing process also takes a lot of time. If a problem is found during the testing process, it needs to be disassembled again for problem location and repair. very low

Therefore, there are problems such as high test cost and cumbersome test process in the existing technology for PCBA testing, which has limited the production efficiency of electronic communication products and cannot meet the needs of technological development.
