Claim One:
1. A method of optimizing parameters of electronic components on printed circuit boards (PCB)s, comprising: obtaining m variables of one type of parameters of P electronic components on a PCB, wherein both m and P are positive integers; setting n values for each of the m variables, wherein n is a positive integer; designing a first experiment table for the m variables using the n values of each of the m variables and the Response surface methodology (RSM), the first experiment table comprising n groups of experiment data of first experiments; obtaining P eye heights (EH)s of each of the first experiments by simulation; computing P EH empirical formulas according to the P EHs obtained from each of the first experiments using a predetermined model formula and mathematical regression analysis; resetting n′ values for each of the m variables, where n′ is a positive integer; designing a second experiment table for the m variables using the n′ values of each of the m variables and the full factorial design, the first experiment table comprising n′ groups of experiment data of second experiments; computing P EHs of each of the second experiments using the P EH empirical formulas; filtering a plurality of experiments from the second experiment tables, all the P EHs of which are greater than 1; computing an average EH of the P EHs of each of the filtered experiment tables; and selecting an experiment from the filtered experiment tables, which has the greatest average EH, and regarding the values of the m variables in the selected experiment as the optimal variables of the parameters.
