Description

Technical Field

[0001] The invention belongs to the technical field of PCB burning, and in particular relates to an automatic burning device for a PB communication board. Background Art

[0002] Online burning, also known as on-board burning, is a technology that directly burns the chip that has been soldered on the PCBA printed circuit board after the SMT process. It does not require consumables such as burning fixtures, and can directly program the chip on the PCB board through the burning compiler. After programming, the board can be functionally tested. Usually, when downloading, you need to prepare hardware equipment tools such as power supply, compiler, PC, download interface cable, etc. Before powering on the device, check whether the installation direction of the download interface cable is correct, and check the communication transmission rate after powering on. Compared with offline burning, the general online burning method is convenient for software updates, but the execution efficiency is not high, there are many related hardware devices, and it is easy to have connection errors and setting errors, which affect the test.

[0024] (2) Through the current / voltage detection function, read the current and voltage changes before and after the PB communication board program is downloaded, and synchronously detect the electrical performance of the implementation object.

[0025] (3) For the PB communication board program compiler software in the integrated host, the download port and rate settings are fixed in advance, and the download can be started with one click.

[0027] (5) The integrated host compares the current and voltage values ​​of the received PB communication board in real time according to the preset current and voltage values. If the current and voltage values ​​of the PB communication board are not within the preset range, the control burner stops burning the PB communication board, and the control module automatically raises the lifting platform to record the unexpected current and voltage values ​​and time to protect the device and the PB communication board, and prevent the current and voltage from being too high due to faults, thereby damaging the automatic burning device and the PCB communication board.
