Abstract
The utility model discloses a kind of welding circuit board structure, circuit board has welding hole, the surface of circuit board is insulating barrier, forms solder joint after described welding hole welding, and forms weldering bridge overlap joint between the described welding hole of conducting to needing on described insulating barrier.The utility model has the advantages that and form weldering bridge again by soldering before needing the solder joint of conducting, being formed between butt welding point puts up a bridge connects, even if there is rosin joint at solder joint place, still can by the circuit between weldering bridge conducting welding hole, avoid the impact that rosin joint produces circuit turn-on, ensure circuit board product quality and normal use, the structure realizing this function is simple, and can not have an impact to other performance of circuit board.
Description
Technical field
The utility model relates to a kind of Welding Structure of circuit board.
Background technology
Welding circuit board causes defect, wherein has following two kinds of situations: 1, the solderability of circuit board apertures affects welding quality.Circuit board apertures solderability is bad, will produce rosin joint defect, affects the parameter of element in circuit, causes multi-layer sheet components and parts and interior layer line conducting instability, causes whole circuit function to lose efficacy.2, the weld defect of warpage generation.Circuit board and components and parts produce warpage in welding process, produce the defect such as rosin joint, short circuit due to stress deformation.
Rosin joint can cause circuit working abnormal, occurs in-and-out wild effect, and noise increases and do not have regularity, brings major hidden danger to the debugging of circuit, operation and maintenance.In addition, also some faulty soldered joint is within one period of long period that circuit is started working, and keeps in touch fair, is therefore not easy to find.But under the effect of the environmental conditions such as temperature, humidity and vibration, contact becomes not exclusively at leisure.The contact resistance of faulty soldered joint can cause local pyrexia, and local temperature raises impels again the solder joint situation of not exclusively contact to worsen further, finally even makes solder joint come off, the complete cisco unity malfunction of circuit.This process is one, two year sometimes.
Numeral shows according to statistics, in electronic system product fault, has half nearly to cause due to failure welding, but will find out from the electronic equipment of thousands of solder joints and cause the faulty soldered joint of fault, this is not a nothing the matter.So rosin joint is a large hidden danger of circuit reliability, must strictly avoid.When carrying out manual welding operation, especially to be noted.
Utility model content
Utility model object: for the problems referred to above, the purpose of this utility model is to provide a kind of Welding Structure that rosin joint can be avoided to affect, and ensures the serviceability of circuit board.
Technical scheme: a kind of welding circuit board structure, circuit board has welding hole, the surface of circuit board is insulating barrier, forms solder joint after described welding hole welding, and forms weldering bridge overlap joint between the described welding hole of conducting to needing on described insulating barrier.
Layers of copper around described welding hole is coated with tin layers, plays the effect helping weldering.
Described weldering bridge shape is trapezoidal or U-shaped.
Beneficial effect: compared with prior art, the utility model has the advantages that and form weldering bridge again by soldering before needing the solder joint of conducting, being formed between butt welding point puts up a bridge connects, even if there is rosin joint at solder joint place, still by the circuit between weldering bridge conducting welding hole, the impact that rosin joint produces circuit turn-on can be avoided, ensure circuit board product quality and normally use, the structure realizing this function is simple, and can not have an impact to other performance of circuit board.
Accompanying drawing explanation
Fig. 1 is front view before welding circuit board;
Fig. 2 is front view after welding circuit board;
Fig. 3 is the A-A cutaway view of Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, circuit board has some welding holes 1, the layers of copper around welding hole 1 is coated with tin layers 5, when butt welding eyelet welding connects, this tin layers plays the effect helping weldering, and the surface of circuit board is insulating barrier 2.
As shown in accompanying drawing 2,3, when circuit board is welded, welding hole 1 is inserted in the end of wire, welding formation solder joint 3 is carried out to it, the interior layer line 6 conducting now in wire and wiring board.
Simultaneously between the solder joint needing conducting, side forms weldering bridge 4 by soldering on the insulating layer, thus overlaps between solder joint.The shape of weldering bridge can be show in Fig. 3 trapezoidal, also can be the shapes such as U-shaped.
Like this, between the solder joint needing conducting, be by the inside cord turning circuit in circuit board on the one hand, turning circuit can also be formed on the other hand by weldering bridge, even if when solder joint rosin joint, still by the circuit turn-on between weldering bridge guarantee solder joint, circuit board can be made by the impact of rosin joint.
Claims (3)
1. a welding circuit board structure, circuit board has welding hole (1), the surface of circuit board is insulating barrier (2), it is characterized in that: after described welding hole (1) welding, form solder joint (3), and form weldering bridge (4) overlap joint to needing between the described welding hole (1) of conducting on described insulating barrier (2).
2. a kind of welding circuit board structure according to claim 1, is characterized in that: described welding hole (1) layers of copper is around coated with tin layers.
3. a kind of welding circuit board structure according to claim 1, is characterized in that: described weldering bridge (4) shape is trapezoidal or U-shaped.
