If these problems cannot be found out, there will necessarily be hidden security trouble in the process of the debugging and application of the PCB. In this paper a new method of testing is proposed tobe against the disadvantages of the present testing methods, which is to ponents on the PCB one byone based on the image template matching method. The fundamental theory of the ponents testing is described in detail, and an optimization is made to the image template matching process using the IDGA based on the FPGA platform, which greatly reduces the cost of the system and plexity of the system design, at the same time a new way and method of the real time application of GA is brought out.
