The invention discloses a collocation method of elements on a circuit board and a computer readable recording medium. The collocation method comprises the following steps: firstly, a database comprising a plurality of rank values is established, a plurality of specific elements are selected from an element base according to an element renewal list, and one rank value is selected as the rank valueof the transferred specific element from the rank values memorized in the database when one of the specific elements is transferred; and secondly, a safe spacing is calculated according to the rank value of the transferred specific element, people use a collocation position as a standard to determine whether a surrounding element exists in the safe spacing, and people determine whether the space between the transferred specific element and the surrounding element conforms to a putting condition when the surrounding element exists in the safe spacing so as to put the transferred specific element at another collocation position or the collocation position.
