Abstract: A method for determining a loading current of a circuit board is provided. In the method, outline positions of metal regions and hollowed regions in each of the metal regions are recorded. Metal widths corresponding to scan lines in circuit board are calculated in a sequence, so that a minimum metal width on each of the scan lines is acquired. According to the minimum metal width, a maximum loading current of each of the metal regions is calculated. In addition, a method and a system for filtering manufacturers are provided. A processing apparatus of the system analyzes the maximum loading current and manufacturing process parameters of the circuit board, calculates a weight score of a manufacturing process capability parameter table of each manufacturer according to the maximum loading current and manufacturing process parameters, and filtering the manufacturers to produce the best fit manufacturer list.

Abstract: A testing system for testing a charging circuit includes a setting unit, a virtual battery, and a control device. The setting unit is utilized for setting a charging configuration of the charging circuit according to a battery status message, to make the charging circuit to output a charging power accordingly. The virtual battery includes a battery status generating unit for generating the battery status message according to a first control signal, and a load unit for generating a load for the charging circuit according to a second control signal, so as to receive the charging power outputted from the charging circuit, and recording variation of the charging power. The control device is utilized for generating the first control signal and the second control signal, and storing information recorded by the load unit as a digital data for evaluate the charging circuit.
