Abstract
The utility model discloses a circuit board card belongs to circuit board card welding field, and the technical problem that solves leads to the cracked emergence between cable and the solder joint for how avoiding long-term atress between cable and the solder joint. At least one via hole is formed in the periphery of each welding point on the circuit board card, cables penetrate through the via holes, and the cables are welded with the welding points after penetrating through the via holes. Before welding, the cable firstly passes through the through hole and then is welded to the welding point nearby after passing through the through hole. The through hole can unload the stress between the cable and the welding point, greatly reduces the chance of fracture between the cable and the welding point, and improves the reliability of products.
Description
Technical Field
The utility model belongs to the technical field of the circuit board welding and specifically relates to a circuit board.
Background
Along with the development of the internet industry, the product forms are more and more, the requirement on product cost compression is higher and higher, and meanwhile, the requirement on the reliability of the product is also more and more. The integrated circuit board is connected with the cable in a plurality of types, and some types of integrated circuit boards are connected in a male head and a female head mode through male heads and female heads in a butt joint mode. In some situations where space is small and cost control is strict, a cable needs to be directly soldered to a solder joint of a PCB. In order to increase the welding firmness, the conventional method increases the welding point and increases the soldering amount. However, as the service life is prolonged and as the cable moves, the situation that the cable and the welding point are broken due to long-term stress between the cable and the welding point occurs, so that the product quality is reduced, and the brand reputation is seriously influenced.
How to avoid the long-term atress between cable and the solder joint to lead to the cracked emergence between cable and the solder joint is the technical problem that needs to solve.
Disclosure of Invention
The technical task of the utility model is not enough more than to, provide a circuit board card, solve how to avoid the problem that the long-term atress leads to the cracked emergence between cable and the solder joint.
The utility model provides a circuit board card, at least one via hole has been seted up to every welding point periphery on the circuit board card, the via hole supplies the cable to pass, and the cable passes behind the via hole and welds with the welding point.
And a resin coating is arranged on the aperture of the via hole.
The cable passes through the via hole and is consolidated in the via hole through the fixed glue.
When the through holes are multiple, the through holes are scattered around the corresponding welding points.
The utility model discloses a circuit board card has following advantage:
1. before welding, the cable firstly passes through the through hole and then is welded to the welding point nearby after passing through the through hole. The through hole can unload the stress between the cable and the welding point, greatly reduces the chance of fracture between the cable and the welding point and improves the reliability of products;
2. reasonable design, simple structure, easy processing, small volume, convenient use, multiple purposes and the like, thereby having good popularization and use values.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without any inventive work.
The present invention will be further explained with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of a circuit board card;
in the figure: 1. circuit board card, 2, welding point, 3, via hole, 4, cable.
Detailed Description
The present invention is further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not intended to limit the present invention, and technical features in the embodiments and examples of the present invention can be combined with each other without conflict.
It is to be understood that "a plurality" in the embodiments of the present invention means two or more.
An embodiment of the utility model provides a circuit board card for solve and how to avoid the problem that long-term atress leads to the cracked emergence between cable 4 and the solder joint.
Example 1:
the utility model discloses a circuit board 1, at least one via hole 3 has been seted up to every welding point 2 peripheries on the circuit board 1, via hole 3 supplies a cable 4 to pass, and cable 4 welds with welding point 2 after passing via hole 3.
Wherein, every welding point 2 corresponds on circuit board card 1 in this embodiment has a via hole 3, and the diameter of via hole 3 is greater than the diameter of corresponding cable 4 a little, with cable 4 welding between corresponding welding point 2, passes through via hole 3 earlier cable 4 and welds to welding point 2 again.
In order to reduce the wear between cable 4 and via hole 3, be provided with the resin layer in the aperture mountain of via hole 3 to cable 4 passes through via hole 3 when with resin layer direct contact, avoids the wearing and tearing of circuit board card to cable 4.
And in order to increase the stability of the cable 4 and the through hole 3, after the cable 4 is welded on the welding point 2 through the through hole 3, the cable 4 is fixed in the through hole 3 through fixing glue.
In order to further increase the effect, can set up a plurality of via holes 3 in welding point 2 department to with a plurality of via holes 3 dispersion at welding point 2 periphery, can further unload the atress between cable 4 and the welding point 2 through a plurality of via holes 3, cracked chance between 4 and the welding point of the greatly reduced cable promotes product reliability.
If a plurality of cables exist, a plurality of groups of corresponding through holes are needed, each group of through holes corresponds to one cable, and at least one through hole is arranged in each group of through holes.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
Claims (3)
1. A circuit board card is characterized in that at least one through hole is formed in the periphery of each welding point on the circuit board card, a cable penetrates through the through hole, and the cable penetrates through the through hole and is welded with the welding point;
