Abstract

The utility model relates to one kind for improving the remaining halftone shelves point of VIA through-hole ink.The edge of shelves point is evenly arranged with 8 shelves mouths, and shelves mouth is triangle, and rectangle washer is set as between two neighboring shelves mouth, and the width of washer is a, and the length of symmetrical two washers is that the size of b, a and b are related with the aperture D of VIA through-hole, and the value range of a is b+2.The utility model structure is simple, compact to design, and the size of the rice word shelves point used can be modified by adjusting rectangular aspect, adjustable, designs simple easy processing, so that the design of product has bigger extension, and then the diversity of product VIA through-hole may be implemented.

Description

One kind is for improving the remaining halftone shelves point of VIA through-hole ink
Technical field
The utility model relates to one kind for improving the remaining halftone shelves point of VIA through-hole ink, belong to wiring board design skill Art field.
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.
Utility model content
Purpose of the utility model is to solve problem, provide that a kind of structure is simple, it is compact to design for improving The remaining halftone shelves point of VIA through-hole ink.
The utility model adopts the following technical solution: one kind is described for improving the remaining halftone shelves point of VIA through-hole ink The edge of shelves point is evenly arranged with 8 shelves mouths, and the shelves mouth is triangle, is set as rectangle shelves between the two neighboring shelves mouth Piece, the width of the washer are a, and the length of symmetrical two washers is the size of b, a and b and the aperture D of VIA through-hole It is related, 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) need to be arranged halftone shelves point as aspect ratio >=8:1 according to the aspect ratio in the section of VIA through-hole first, when vertical Horizontal ratio does not need then when being 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 utility model structure is simple, compact to design, the size of the rice word shelves point used can by adjust rectangular aspect into Row modification, it is adjustable, simple easy processing is designed, so that the design of product has bigger extension, and then product may be implemented The diversity of VIA through-hole.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference: shelves mouth 1, washer 2.
Specific embodiment
Below in conjunction with attached drawing, the utility model 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 is 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; When 24.8 < D≤29.8, b 8mil, a 10mil;When 29.8 < D≤34.8, b 9mil, a 11mil;34.8 < D≤ When 39.8, b 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.
