Chip burning method and system and computer readable storage medium

Abstract

The invention provides a chip burning method and system and a computer readable storage medium, and the method comprises the steps: enabling a PCB with a plurality of independent chips to be moved toa position below a burning device, and enabling a plurality of burning needles in array arrangement to cover each independent chip in the PCB; acquiring original image information of the PCB; performing image processing on the original image information to obtain a corresponding grayscale image, analyzing a grayscale value of each point location in the grayscale image, and judging the point location of which the grayscale value is greater than a first preset threshold value as an electric connection point; analyzing the size of each electric connection point, and judging the electric connection point of which the size is smaller than a second preset threshold value as a burning point; marking coordinate positions of all burning points in the original image information; and selecting the burning needles corresponding to all the burning points based on the coordinate positions of all the burning points, and controlling the burning needles to be in contact with the burning points so as toburn a program for the chip. According to the invention, a full-automatic chip burning process is realized, and the yield of chip burning is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of chip programming, in particular to a chip programming method, system and computer-readable storage medium. Background technique [0002] At present, most electronic products on the market need to be controlled by chips, so it is necessary to program the chips. [0003] In the field of production of control equipment such as automotive ECU modules and air-conditioning control modules, it is necessary to burn the relevant control logic programs into the chip after the circuit is assembled. When programming the chip, it is necessary to fix the chip or related circuit board on the fixture and other instruments, and connect it with the programmer installed on the fixture, and then operate the host computer to control the programmer to burn the chip, and then burn the chip. After recording, remove the chip or circuit board from the fixture to complete the programming of a chip. [0004] The hardware structure...

Problems solved by technology

First of all, the operator needs to correspond one-to-one with the software serial number of the chip and the position number of the chip on the circuit board when programming the chip. The operation is cumbersome and complicated, and only one chip can be burned at a time. The work efficiency is low and mass production cannot be achieved requirements; secondly, during the programming process, the operator is likely to make a wrong correspondence between the software serial number and the chip position number, resulting in defective products.
