A method for finding manufactured or to-be-manufactured products for defects includes obtaining basic information on processing history of products passed by each manufacturing machine at each processing workstation, and obtaining processing factor information of same, where each product is passed by a defect detection workstation after the product is passed by at least one processing workstation. The method includes obtaining quality information detected by each defect detection workstation. The method determines one or more problem manufacturing machines at one or more problem processing workstations according to the basic information on processing history and the quality information of the products. The method further determines one or more processing factors which influence the problem manufacturing machines according to the processing factor information of each manufacturing machine and the quality information of the products. A related electronic device and non-transitory storage medium are also provided.

A method for setting parameters in design of a printed circuit board (PCB) includes obtaining multiple combinations of layout parameters of a PCB and inputting the multiple combinations of layout parameters into a predetermined PCB layout simulation software to obtain multiple interference parameter combinations. The multiple combinations of layout parameters and the multiple interference parameter combinations are defined as training samples, and a predetermined network model is trained through the training samples to obtain a first prediction model. The first prediction model is trained and tested to obtain an impedance prediction model. When the multiple combinations of layout parameters are inputted to the impedance prediction model, only an average predetermined error is allowed between impedance values predicted by the impedance prediction model and impedance values calculated by the predetermined PCB layout simulation software, to enable acceptance of that combination.
