D rilling is a key process in the production of printed circuit board (PC B ). Pressure foot plays an im portant role in the drilling process,and the w orkpiece m achining quality is close related w ith the com bining form of pressure foot and sucking dust cover. T he m ainstream com binatorial structures in the m arket are analysed w ith the help of test com bined w ith num erical sim ulation m ethod. T he paper presents a system atic solution of pressure foot design in engineering,appropriate param eter is obtained on the basis of a series of tests to achieve high perform ance of dust collection and high quality drilling.
