Description

PCB with dispensing screen printing function

Technical Field

The utility model belongs to the technical field of the printed circuit board design and specifically relates to a PCB board with point silk screen printing is glued.

Background

PCBs, also called printed circuit boards, are important electronic components that are essential in electronic and electrical products, and are supports for electronic components and carriers for electrical connection. And usually the positive back all can bear some sizes great on the PCB board, and heavier electronic components such as big inductance component, big electric capacity component, BGA component, big IC component etc. when these large-scale components are in the machine in-process of crossing reflow soldering, can appear raising in batches and fall a scheduling problem, the quality of reduction product that can be great, so people meet the characteristic that high temperature solidifies according to specific glue class, carry out some glue to these large-scale components and fix. It can't be known clearly which electronic components need to be glued and reinforced on the PCB board, and it can't be known clearly which positions of electronic components are reinforced and the shape is glued to specific point either for the glue dispensing process is time consuming and laborious.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a PCB board with point is glued silk screen printing, include: a PCB body; the surface layer of the PCB body is provided with electronic components; and the corners of the electronic components are provided with adhesive dispensing silk-screen printing.

Preferably, the dispensing silk-screen printing is circular silk-screen printing; the circular silk-screen printing is divided into three circular silk-screen printing at the top and two circular silk-screen printing at the two sides; the central point of the vertex round silk-screen is arranged at the vertex of the outline silk-screen corner of the electronic component; the central points of the two side circular silk screens are respectively positioned on the two right-angle side silk screens at the corners of the external silk screen of the electronic component.

Preferably, the diameter of the circular silk screen is 1mm.

Preferably, the distance between the edge of the side circular silk screen and the edge of the vertex circular silk screen is 1mm.

Preferably, the dispensing silk-screen printing is an L-shaped silk-screen printing, and the inner right-angle vertex of the L-shaped silk-screen printing is located at the vertex of the corner of the appearance silk-screen printing of the electronic component.

Preferably, the width of the L-shaped screen printing is 1mm, and the length of the outer edge of two sides of the L-shaped screen printing is 4.3mm.

Preferably, the electronic components have four corners.

The beneficial effects of the utility model are that: the utility model provides a PCB board with point silk screen printing, according to special point on the PCB board glue the position of silk screen printing, shape and size, can clearly and definitely know which electronic components need glue on the PCB board and glue the reinforcement, also know at which position of electronic components consolidate and concrete point and glue the shape for the point is glued technology and is more high-efficient, economize the material. Thereby improving the production quality and the production efficiency of the product.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1-3 of the present invention, and it should be apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1, the electronic component 2 is located on the surface layer of the PCB body 1, and the dispensing silk-

screen

3 or 4 is disposed at four corners or two opposite corners of the electronic component that needs dispensing treatment, so that dispensing can be performed in a dot manner according to the shape and position of the circular silk-screen 3, or in a linear manner according to the shape and position of the "L" shape silk-screen 4. Therefore, the electronic component 2 is large in size, and after the component with heavy mass is glued and reinforced, the situation that the component is stilted or falls in a reflow soldering machine is avoided, the production quality and the production efficiency of the product are effectively improved, and the labor cost and the material cost are saved.

A PCB board with point-and-screen printing includes: a PCB body; the surface layer of the PCB body is provided with electronic components; and the corners of the electronic components are provided with adhesive dispensing silk-screen printing.

As shown in fig. 2, the dispensing silk-screen is a circular silk-screen; the circular silk-screen printing is divided into three circular silk-screen printing at the top and two circular silk-screen printing at the two sides; the central point of the vertex round silk-screen is arranged at the vertex of the outline silk-screen corner of the electronic component; the central points of the two side circular silk screens are respectively positioned on the two right-angle side silk screens at the corners of the external silk screen of the electronic component.

The diameter of the circular silk screen is 1mm.

The distance between the edge of the side circular silk screen printing and the edge of the vertex circular silk screen printing is 1mm.

As shown in fig. 3, the dispensing screen printing is L-shaped screen printing, and the inner right-angle vertex of the L-shaped screen printing is located at the vertex of the corner of the outline screen printing of the electronic component.

The width of the L-shaped silk screen is 1mm, the length of the outer edge of two sides of the L-shaped silk screen is 4.3mm, the detailed values are shown in figure 3, the adhesive strength is strong enough, and the structure in figure 2 is weaker than that in figure 3, so that the L-shaped silk screen is more suitable for chips with smaller size. The structure of fig. 2 can also continue to move right and up, and the dispensing circles can be added at equal intervals to increase the strength, and the size of the dispensing circle can be changed to increase the strength, for example, the diameter of the dispensing circle at the vertex is increased to 1.5mm. According to the size of the chip, the size of the dispensing circle can be adjusted to control the dispensing amount.

The electronic component has four corners.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
