Abstract
The utility model provides a welding pore structure, it is opened on a pcb board, for injecting after tin cream the fixed feet for welding an element, the welding pore structure taper at an acute angle and including a upper opening and a under shed, the upper opening is opened in the upper surface of the pcb board, the under shed is opened in the lower surface of the pcb board and in the upper opening concentric, and the diameter of the under shed is less than the diameter of the upper opening.
Description
Technical field
The utility model is a kind of welding pore structure.
Background technique
Currently, in production, the fixed feet of SMT high frequency connectors, since welding hole is usually straight hole, is being printed in upper tin
When brush, having part tin can not inject in welding hole, and partially due to the aperture of PCB under shed is big and tin cream will appear it is de-
Leakage, and then lead to few tin phenomenon occur, it is main to show light transmission and recessed tin.Thus, it has to do over again, lead to manpower and material
Expect the waste of cost, and greatly reduces working efficiency.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of welding pore structures, and it is existing to can avoid above-mentioned few tin
As.
In order to solve the above technical problems, the utility model provides a kind of welding pore structure, it is opened on a pcb board, uses
The fixed feet of an element is welded after injecting tin cream, the welding pore structure taper at an acute angle and including a upper opening and is once opened
Mouthful, which is opened in the upper surface of the pcb board, which is opened in the lower surface of the pcb board and same in the upper opening
The center of circle, the diameter of the under shed are less than the diameter of the upper opening.
Preferably, which is high frequency connectors.
Compared with prior art, the welding pore structure of the utility model takes acute angle conical design, due to the upper opening
Be relatively large in diameter, when printing, tin cream can be fallen by the upper opening in welding pore structure, and the bottom under shed in hole is smaller, tin cream
Tin cream is all drawn in the welding pore structure by the cohesion pulling force of itself, such tin will increase and not occur leaking under tin, so that it may
The phenomenon that welding required tin to meet, avoid few tin.
[Detailed description of the invention]
Fig. 1 is the partial schematic diagram of the circuit board with the utility model welding hole.
Fig. 2 is the schematic cross-section of Fig. 1.
[specific embodiment]
It please refers to shown in Fig. 1-2, the utility model provides a kind of welding pore structure 1, is opened in a PCB (Printed
Circuit Board, printed circuit board) on plate 2, for injecting after tin cream the fixed feet (not shown) for welding an element.In this reality
It applies in example, the taper at an acute angle of welding pore structure 1 and including a upper opening 10 and a under shed 11.The upper opening 10 is opened in
The upper surface of the pcb board 1, which is opened in the lower surface of the pcb board 1, and the diameter of the under shed 11 is less than on this
The diameter of opening 10.
In the present embodiment, which is high frequency connectors.
When being printed using the welding pore structure 1 of the utility model, due to being relatively large in diameter for the upper opening 10, printing
When, tin cream can be fallen by the upper opening 10 in welding pore structure 1, and the bottom under shed 11 in hole is smaller, and tin cream passes through itself
Cohesion pulling force all draws tin cream in the welding pore structure 1, and such tin will increase and not occur leaking under tin, so that it may to meet welding
Required tin avoids the phenomenon that lacking tin, and is equivalent to has thickeied steel plate print tin simultaneously.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be wanted with right
Subject to the protection scope asked.
Claims (2)
1. a kind of welding pore structure, is opened on a pcb board, special for injecting after tin cream the fixed feet for welding an element
Sign is, the welding pore structure taper at an acute angle and including a upper opening and a under shed, which is opened in the pcb board
Upper surface, the under shed be opened in the lower surface of the pcb board and with the upper opening concentric, the diameter of the under shed is less than should
The diameter of upper opening.
2. welding pore structure according to claim 1, which is characterized in that the element is high frequency connectors.
