Description
Technical field
The present invention relates to one kind for improving the remaining halftone shelves point of VIA through-hole ink, belongs to wiring board design technology neck
Domain.
Background technique
With the high speed development of electronic product, many special products are in requisition for special demand, traditional wiring board
Design is difficult to meet some specific demands, such as: the heat dissipation of QFN chip, the welding of plug-in unit part, according to traditional shelves point side
Formula makes the VIA through-hole of small-bore, and general diameter is in 9.8 ~ 15.7mil, and plate thickness is in 60mil or more, if needing common shelves point
Design, can make has a large amount of ink in the hole VIA, is unfavorable for punching of developing, if the diameter of common shelves point design is increased, at aperture
The problems such as will cause leakage copper.
Summary of the invention
The purpose of the present invention is to solve problem, provide that a kind of structure is simple, compact to design is logical for improving VIA
The remaining halftone shelves point of hole ink.
The present invention adopts the following technical scheme: a kind of for improving the remaining halftone shelves point of VIA through-hole ink, the shelves point
Edge be evenly arranged with 8 shelves mouths, the shelves mouth is triangle, be set as rectangle washer between the two neighboring shelves mouth,
The width of the washer is a, and the length of symmetrical two washers is that the size of b, a and b and the aperture D of VIA through-hole have
It closes, and the value range of a is b+2.
Further, the shelves are selected in rice font.
Further, when VIA through-hole aperture D is less than 9.8 mil, b 4mil, a 6mil.
Further, as 9.8 < D≤14.8 of VIA through-hole aperture, b 5mil, a 7mil.
Further, as 14.8 < D≤19.8 of VIA through-hole aperture, b is 6 mil, a 8mil.
Further, as 19.8 < D≤24.8 of VIA through-hole aperture, b is 7 mil, a 9mil.
Further, as 24.8 < D≤29.8 of VIA through-hole aperture, b 8mil, a 10mil.
Further, as 29.8 < D≤34.8 of VIA through-hole aperture, b 9mil, a 11mil.
Further, as 34.8 < D≤39.8 of VIA through-hole aperture, b 10mil, a 12mil.
Further, the design process of shelves point includes the following steps:
(1) it needs to be arranged halftone shelves point as aspect ratio >=8:1 according to the aspect ratio in the section of VIA through-hole first, works as aspect ratio
It is not needed then when less than 8:1；
(2) the width a and length b of shelves point are set according to the aperture D of VIA through-hole；
(3) select the halftone of corresponding mesh number for substrate according to the size of shelves point；
(4) several grade of point is plotted on halftone respectively, carries out production printing.
The configuration of the present invention is simple, compact to design, the size of the rice word shelves point used can be repaired by adjusting rectangular aspect
Change, it is adjustable, simple easy processing is designed, so that the design of product has bigger extension, and then it is logical that product VIA may be implemented
The diversity in hole.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Appended drawing reference: shelves mouth 1, washer 2.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described.
As shown in Figure 1, a kind of for improving the remaining halftone shelves point of VIA through-hole ink, the edge of shelves point is evenly arranged with
8 shelves mouths 1, shelves mouth 1 are triangle, are set as rectangle washer 2 between two neighboring shelves mouth 1, and the width of washer 2 is a, and symmetrical two
The length of a washer 2 is that the size of b, width a and length b are related with the aperture D of VIA through-hole, and the value range of a is b+2；
When VIA through-hole aperture D is less than 9.8 mil, b 4mil, a 6mil；As 9.8 < D≤14.8, b 5mil, a are
7mil；When 14.8 < D≤19.8, b is 6 mil, a 8mil；When 19.8 < D≤24.8, b is 7 mil, a 9mil；24.8 <
When D≤29.8, b 8mil, a 10mil；When 29.8 < D≤34.8, b 9mil, a 11mil；When 34.8 < D≤39.8, b
For 10mil, a 12mil.
Design procedure is as follows:
A, confirm VIA through-hole minimum-value aperture on substrate, calculate whether its aspect ratio is more than or equal to 8:1；Pass through client's
Gerber data, finds out that its minimum VIA through-hole aperture is 9.8mil, finished product plate thickness requirement is 78.4mil, calculates aspect ratio
For 8:1, judgement needs to enable such design；
B, the design of rice font shelves point calculates the length and width of each rectangle of composition rice font shelves point according to VIA through-hole aperture are as follows:
11.8milX4mil；
C, it according to the minimum aperture VIA, calculates the minimum of halftone mesh number and requires to be 110 mesh；
D, by designed rice font shelves point-rendering to selected halftone, production printing is carried out.
