Abstract

The utility model is related to a kind of PCB pads components, including pcb board, PCB pad groups, for welding corresponding with the component pads of to-be-welded elements, it is divided into two rows and is arranged at intervals on the pcb board, include that distance is less than the centre distance of the component pads positioned at the first PCB pads at four angles and between the 2nd PCB pads of other positions, two rows of PCB pads groups;Steel mesh groups of openings, it is described to be used to store tin cream, including the second steel mesh trepanning of the 2nd PCB pads periphery described in the first steel mesh trepanning and setting of the first PCB pads periphery is set.The utility model improves the bad problem of part rosin joint.

Description

A kind of PCB pads component
Technical field
The utility model is related to a kind of pad structure more particularly to a kind of PCB pads components.
Background technology
With scientific and technological progress, the trend of component size development increasingly minimizes, and component size is smaller to SMT working abilities It is required that higher, and PCB pad designs obtain too big, and SMT be easy to cause Component Displacement;PCB pad designs it is too small, be unfavorable for element Thrust is tested, and is be easy to cause element and is fallen off.
Fig. 1 is a kind of constitutional diagram of the PCB pads 20 and part pad 40 of corresponding Element Design, part pad 40 and PCB In the case of existing production, part pad 40 overlaps pad 20 with the edge projection of PCB pads 20, if part is pasted in SMT Slight displacement occurs during piece, it is inconsistent to easily lead to part both sides contact pads tin cream amount, crosses stove and generates displacement.Displacement makes member Part has the quality hidden danger of rosin joint, and the stability of product is poor, is unfavorable for producing.
Utility model content
The purpose of this utility model is to be directed to above-mentioned present situation, provides a kind of PCB pads component.
The technical solution adopted in the utility model:A kind of PCB pads component, including:
Pcb board,
PCB pad groups are divided into two rows and are arranged at intervals on described for welding corresponding with the component pads of to-be-welded elements Include positioned at the first PCB pads at four angles and positioned at the 2nd PCB pads of other positions, two rows of PCB welderings on pcb board Distance is less than the centre distance of the component pads between disk group;
Steel mesh groups of openings, it is described to be used to store tin cream, including the first steel mesh being arranged in the first PCB pads periphery is opened Second steel mesh trepanning of the 2nd PCB pads periphery described in hole and setting.
The effect of the utility model is:Improve the bad problem of part rosin joint.
Description of the drawings
Fig. 1 is a kind of existing structural schematic diagram of PCB pads;
Fig. 2 is a kind of structural schematic diagram of PCB pads component of the utility model;
Fig. 3 is that PCB pads shown in Fig. 2 and being used cooperatively for to-be-welded elements are schemed.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality It is novel, it is not intended to limit the scope of the utility model.
As shown in Fig. 2, a kind of PCB pads component provided by the utility model, including the setting of pcb board 1, two-row spacing exist PCB pads 2 on pcb board 1 and the steel mesh trepanning 3 in 2 periphery of each PCB pads is set;PCB pads 2 are used for and member to be welded The component pads of part correspond to welding, and steel mesh trepanning 3 is for storing tin cream.
As shown in figure 3, the spacing of adjustment two rows PCB pads 2, distance d2 is less than to-be-welded elements between making PCB pads 2 Component pads centre distance d1.Two rows of PCB pads 2 adjust 0.15mm to offside respectively, i.e., distance d2 is less than between PCB pads 2 The component pads centre distance d1 of to-be-welded elements is 0.3mm, and part pad 4 is made to completely attach to tin cream.Even if part is pasted in SMT Slight displacement occurs during piece, but the pulling force that the tin cream on pcb board generates during crossing stove can also draw positive part.
The location diagram of steel mesh trepanning 3 and PCB pads 2 is also as shown in Fig. 2, iron net trepanning 3 is arranged in PCB pads 2 Periphery.Specifically, the first steel is extended to form outward respectively positioned at the outside two edges of four the first PCB pads 21 at four angles Net trepanning 31 extends to form the second steel mesh positioned at the 2nd PCB pads 22 only direction of long side edge outward of other positions and opens Hole 32.
Preferably, the long side of each first PCB pads 21 is along the direction water far from the first adjacent PCB pads of its opposite Flat to extend 0.2mm, the short side of each first PCB pads 21 is horizontal along the direction far from the first adjacent PCB pads of its same column Extend 0.15mm, and then forms the first steel mesh trepanning 31.
Preferably, the direction of the long side of each 2nd PCB pads 22 outward extends 0.2mm, and then forms the second steel Net trepanning 32.
It is arranged along the circumferentially enlarged steel mesh trepanning of PCB pads, increases tin cream amount, it is bad to further decrease part rosin joint.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
