Abstract
The present invention relates to a kind of printed board drilling drawing coefficient data processing method, described printed board comprises cell board and test-strips, described data processing method comprises the following steps: 1) on four angles of test-strips, with the boring of the ratio boring sum 1/3rd of 1:1, the biased difference in contrast hole is how many, thus calculate preliminary drilling drawing coefficient, then perform step 2); 2) hole by preliminary drilling drawing coefficient the boring of sum 1/3rd, contrast hole biased difference is how many, determines whether this drilling drawing coefficient meets the requirements, if yes, then draws drilling drawing coefficient, if NO, then performs step 3 again); 3) by step 2) drilling drawing coefficient continues the boring of boring remaining 1/3rd, and contrast hole biased difference is how many, determines drawing coefficient.Compared with prior art, the present invention has cost-saving, the advantage such as accurate more directly perceived.
Description
Technical field
The present invention relates to a kind of correlation technique of printed board drilling drawing coefficient, especially relate to a kind of printed board drilling drawing coefficient data processing method.
Background technology
Because can there is the impact of harmomegathus after sheet material baking, pressure, the control for borehole accuracy just brings very large trouble.Determine in the industry drilling drawing coefficient at present, generally determine the drawing coefficient of drilling by the harmomegathus coefficient of the test film or first take one block of first plate to hole in the ratio of 1:1, confirm that drawing coefficient starts boring again, these two kinds of methods all directly can not draw actual drawing coefficient, the waste on cost can be caused like this, particularly some high laminates, the plate of special substance, cost is higher.
Summary of the invention
Object of the present invention is exactly provide a kind of cost-saving, the more directly perceived drawing coefficient of printed board drilling accurately data processing method to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of printed board drilling drawing coefficient data processing method, described printed board comprises cell board and test-strips, it is characterized in that, described data processing method comprises the following steps:
1) on four angles of test-strips, with the boring of the ratio boring sum 1/3rd of 1:1, the biased difference in contrast hole is how many, thus calculates preliminary drilling drawing coefficient, then performs step 2);
2) hole by preliminary drilling drawing coefficient the boring of sum 1/3rd, contrast hole biased difference is how many, determines whether this drilling drawing coefficient meets the requirements, if yes, then draws drilling drawing coefficient, if NO, then performs step 3 again);
3) by step 2) drilling drawing coefficient continues the boring of boring remaining 1/3rd, and contrast hole biased difference is how many, determines drawing coefficient.
Described test-strips is positioned at cell board both sides, the drilling testing hole, four Angle Position places outside cell board and ectonexine all adds weld-ring, is confirmed the drawing coefficient of drilling during production by drilling testing hole.
Compared with prior art, the present invention has the following advantages:
1) cost because first plate produces has been saved to a great extent.
2) determine that the harmomegathus coefficient of every one deck determines an optimal boring drawing coefficient by playing section, it is more directly perceived more accurate.
Accompanying drawing explanation
Fig. 1 is hardware structure diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, printed board of the present invention comprises cell board 1 and test-strips 2, and test-strips 2 is positioned at cell board 1 both sides.We are when engineering makes, and the rational position place at four angles outside the means of production increases some instrument connections 3 and ectonexine all adds weld-ring, is confirmed the drawing coefficient of drilling during production by drilling testing hole; Whole process can divide three steps to realize.
A kind of printed board drilling drawing coefficient data processing method, concrete grammar step is:
Step 101. is on four angles of test-strips 2, and the boring of sum 1/3rd of holing by the ratio of 1:1, contrasts the biased difference in hole how many, thus preliminary confirmation drilling drawing coefficient, then perform step 102;
Step 102. hole by the preliminary drawing coefficient confirmed the boring of sum 1/3rd again, and the biased difference in contrast hole is how many, determines that whether drawing coefficient is desirable, if test result is desirable, then draws drilling drawing coefficient, if undesirable, then and execution step 103;
Step 103. continues the boring of boring remaining 1/3rd by the drawing coefficient that first two steps are determined, determines drawing coefficient.
Claims (2)
1. a printed board drilling drawing coefficient data processing method, described printed board comprises cell board and test-strips, it is characterized in that, described data processing method comprises the following steps:
1) on four angles of test-strips, with the boring of the ratio boring sum 1/3rd of 1:1, the biased difference in contrast hole is how many, thus calculates preliminary drilling drawing coefficient, then performs step 2);
2) hole by preliminary drilling drawing coefficient the boring of sum 1/3rd, contrast hole biased difference is how many, determines whether this drilling drawing coefficient meets the requirements, if yes, then draws drilling drawing coefficient, if NO, then performs step 3 again);
3) by step 2) drilling drawing coefficient continues the boring of boring remaining 1/3rd, and contrast hole biased difference is how many, determines drawing coefficient.
2. a kind of printed board drilling drawing coefficient data processing method according to claim 1, it is characterized in that, described test-strips is positioned at cell board both sides, drilling testing hole, four Angle Position places outside cell board and ectonexine all adds weld-ring, confirms the drawing coefficient of drilling by drilling testing hole during production.
