Fig. 1 is the schematic flow sheet of polar coordinates method for building up one embodiment of PCB of the present invention.
With reference to Fig. 1, the polar coordinate system method for building up of PCB of the present invention may further comprise the steps:
The required parameter of polar coordinate system is set up in step S10, reception;
Polar coordinates are two-dimensional coordinate systems, o'clock being represented by the distance of an angle and one section relative central point (limit) in this coordinate system.Can pass through polar coordinates initial point, start angle, warp interval, parallel number of rings, parallel at interval so set up a polar coordinate system; Can confirm a polar coordinate system; Therefore, the required parameter of polar coordinate system of setting up that step S01 receives comprises polar coordinates initial point, start angle, warp interval, parallel number of rings, parallel at interval.If do not have polar coordinates initial point and start angle in this parameter, then this polar coordinates initial point can default setting be the initial point in the rectangular coordinate system before, and start angle then default setting is 0 °.

0Be the basis, set up warp, the angle between this warp and the pole axis is n*20 °.Wherein, the warp sequence number of n for setting up.As shown in Figure 3:
When setting up article one warp, be the basis with the pole axis, draw the straight line that passes the polar coordinates initial point, the angle between this straight line and the pole axis is 20 °;
When setting up the second warp, be the basis with the pole axis, draw the straight line that passes the polar coordinates initial point, the angle between this straight line and the pole axis is 40 °.
The rest may be inferred, all sets up until all warps.
Certainly, the corresponding function function that the foundation of this parallel also can be called in the drawing instrument is once set up, for example array functional among the CAD or the like.
Step S113, with the combination of the warp of being set up and parallel, form polar grid;
With the combination of the warp of being set up and parallel, because the central point of warp and parallel is the polar coordinates initial point, so warp and parallel with arranged in a crossed manner, and form a plurality of polar grid points.
Step S114, obtain the positional information of all net points in the said polar grid.
According to setting up good polar grid, obtain the positional information of all net points in all polar grids, so that with its preservation.
