Description
Technical Field
The invention relates to a screen printing plate blocking point for improving VIA through hole ink residue, and belongs to the technical field of circuit board design.
Background
With the rapid development of electronic products, many special products are required to meet special requirements, and the traditional circuit board design is difficult to meet some special requirements, such as: the heat dissipation of QFN chip, the welding of plug-in components part, if adopt traditional shelves point mode to make the VIA through-hole of aperture, general diameter is 9.8~15.7mil, and the plate thickness is 60mil and above, if need ordinary shelves point design, can make there is a large amount of printing ink in the VIA hole, be unfavorable for developing the punching a hole, if increase the diameter of ordinary shelves point design, can cause the problem such as copper leakage in drill way.
Disclosure of Invention
The invention aims to solve the problem and provides a screen printing plate blocking point which is simple in structure and compact in design and is used for improving the ink residue of a VIA through hole.
The invention adopts the following technical scheme: 8 baffle openings are uniformly formed in the edge of each baffle point, each baffle opening is triangular, a rectangular baffle plate is arranged between two adjacent baffle openings, the width of each baffle plate is b, the distance between two symmetrical baffle plates is a, the sizes of a and b are related to the aperture D of the VIA through hole, and the value of a is b+2mil; the stop points are in a shape of Chinese character 'mi'.
Further, when VIA hole diameter D is less than 9.8mil, b is 4mil and a is 6mil.
Further, when VIA VIA hole diameter is 9.8mil < D.ltoreq.14.8 mil, b is 5mil and a is 7mil.
Further, when VIA VIA hole diameter is 14.8mil < D.ltoreq.19.8 mil, b is 6mil and a is 8mil.
Further, when VIA VIA hole diameter 19.8mil < D.ltoreq.24.8 mil, b is 7mil and a is 9mil.
Further, when VIA VIA hole diameter is 24.8mil < D.ltoreq.29.8 mil, b is 8mil and a is 10mil.
Further, when VIA VIA hole diameter 29.8mil < D.ltoreq.34.8 mil, b is 9mil and a is 11mil.
Further, when VIA VIA hole diameter 34.8mil < D.ltoreq.39.8 mil, b is 10mil and a is 12mil.
Further, the design process of the shift point comprises the following steps:
(1) First, according to the aspect ratio of the cross section of the VIA through hole, when the aspect ratio is equal to or greater than 8:1, screen printing plate blocking points are required to be set, and when the aspect ratio is smaller than 8:1, the screen printing plate blocking points are not required;
(2) Setting the width a and the length b of the baffle point according to the aperture D of the VIA through hole;
(3) Selecting a screen printing plate with corresponding mesh number as a substrate according to the size of the gear points;
(4) And respectively drawing a plurality of stop points on the screen printing plate to carry out production printing.
The invention has simple structure and compact design, the size of the used rice-shaped baffle point can be modified by adjusting the length and the width of the rectangle, the size of the baffle point is adjustable, the design is simple and easy to process, the design of the product has larger extension, and the diversity of the VIA through holes of the product can be realized.
Drawings
