Description
Technical field
The present invention relates to printed-board technology, particularly relate to a kind of method and a kind of printed circuit board (PCB) that prevents that the ring-shaped inductors on printed circuit board (PCB) from coming off.
Background technology
On the various circuit arrangements based on printed circuit board (PCB), such as computer main board, display card etc., except being welded with various integrated chips, be also welded with the peripheral components such as electric capacity, inductance on it.Ring-shaped inductors is a kind of form of inductance, and it is also through being usually used on printed circuit board (PCB).
Fig. 1 a is a kind of Facad structure schematic diagram of ring-shaped inductors, and Fig. 1 b is the side schematic view of this ring-shaped inductors.Ring-shaped inductors is generally made up of magnet ring and the coil that is wrapped on magnet ring, and the initiating terminal of pin and coil and end are connected respectively draws and fixes.For protection ring-shaped inductors, sometimes also at the outside containment vessel that increases of whole coil.Its coil generally adopts enamelled wire, and pin is exactly directly will after the end of a thread peeling wicking of enamelled wire, to form conventionally.
Can see, based on this structure of ring-shaped inductors, because the weight (comprising the weight of magnet ring and coil) of inductance entirety is larger, and the intensity of pin is inadequate simultaneously, this just easily causes printed circuit board (PCB) in the time being subject to slightly large shock disturbance, and ring-shaped inductors comes off from printed circuit board (PCB).In the time that complete machine is carried out to drop test, the pin of ring-shaped inductors is easily fracture just, causes ring-shaped inductors and comes off.
Summary of the invention
Based on this, be necessary to provide a kind of method of causing the ring-shaped inductors on printed circuit board (PCB) to come off owing to the shock such as falling of preventing.
A kind of method that prevents that the ring-shaped inductors on printed circuit board (PCB) from coming off, comprise the steps: described ring-shaped inductors to be arranged on the position near the device fixedly securing on printed circuit board (PCB), the shock side of printed circuit board (PCB) is positioned at the offside of described ring-shaped inductors with respect to the described device fixedly securing.
Therein in an embodiment, the device that the technical front of described ring-shaped inductors fixedly secures described in facing.
In an embodiment, described ring-shaped inductors is placed between the device fixedly securing described at least two therein.
Therein in an embodiment, the distance between described ring-shaped inductors and the device that fixedly secures is less than 5 millimeters.
Therein in an embodiment, between described ring-shaped inductors and the device that fixedly secures, be also provided with bolster.
In an embodiment, described bolster is white glue therein.
Therein in an embodiment, described in the device that fixedly secures be electrochemical capacitor.
A kind of printed circuit board (PCB), comprises ring-shaped inductors and the electrochemical capacitor be located on plate body, and described ring-shaped inductors is arranged on the position near described electrochemical capacitor, and the shock side of printed circuit board (PCB) is positioned at the offside of described ring-shaped inductors with respect to described device.
In an embodiment, the distance between described ring-shaped inductors and electrochemical capacitor is less than 5 millimeters therein.
In an embodiment, between described ring-shaped inductors and electrochemical capacitor, be also provided with bolster therein.
Said method and printed circuit board (PCB), owing to ring-shaped inductors being arranged near the position that can fixedly secure the device on printed circuit board (PCB), in the time that circuit board is subject to clashing into, the device fixedly securing can stop that ring-shaped inductors significantly departs from original position, thereby can prevent from coming off because of pin breakage.
Accompanying drawing explanation
Fig. 1 a is a kind of Facad structure schematic diagram of ring-shaped inductors;
Fig. 1 b is the side schematic view of ring-shaped inductors shown in Fig. 1 a;
Fig. 2 is a kind of printing circuit board element schematic layout pattern.
Embodiment
As shown in Figure 2, be a kind of printing circuit board element schematic layout pattern.This printed circuit board (PCB) 10 is provided with ring-shaped inductors 100, electrochemical capacitor 200 and chip 300 etc.The method that the ring-shaped inductors on printed circuit board (PCB) comes off that prevents of one embodiment is provided, and ring-shaped inductors 100 is arranged on the position near the electrochemical capacitor 200 on printed circuit board (PCB) 10 by the method, and ring-shaped inductors 100 is positioned at the offside of the shock side of electrochemical capacitor 200.Like this, in the time making ring-shaped inductors 100 depart from original position because of shock, electrochemical capacitor 200 can stop ring-shaped inductors 100, prevents that it from causing pin breakage because clashing into the skew producing.
Preferably, the technical front of ring-shaped inductors 100 is in the face of electrochemical capacitor 200.The front of ring-shaped inductors 100 is the ring surface of coil entirety, can see that wire is from outwards arrangement radially of hub of a spool from the front of ring-shaped inductors 100.Correspondingly be the side of ring-shaped inductors 100.The front of ring-shaped inductors 100 is faced electrochemical capacitor 200 and can be made electrochemical capacitor 200 can stop preferably ring-shaped inductors 100.
Preferably, ring-shaped inductors 100 is placed between at least two electrochemical capacitors 200.Electrochemical capacitor 200 just can stop ring-shaped inductors 100 from both direction at least like this, prevents that it from causing pin breakage because clashing into the skew producing.
Preferably, the distance between ring-shaped inductors 100 and electrochemical capacitor 200 is less than 5 millimeters.5 millimeters of following distances can guarantee that electrochemical capacitor 200 can stop ring-shaped inductors 100 preferably.When distance is while being greater than 5 millimeters, ring-shaped inductors 100 tilts owing to may possessing enough spaces, still likely causes pin breakage and comes off.
Preferably, between ring-shaped inductors 100 and electrochemical capacitor 200, be also provided with bolster 400.Bolster 400 can cushion the interaction force between ring-shaped inductors 100 and electrochemical capacitor 200, can avoid the shock that may occur to damage.In one embodiment, this bolster 400 is white glue.White glue has certain viscosity and insulation, can be added between ring-shaped inductors 100 and electrochemical capacitor 200 in the later stage of making printed circuit board (PCB).
In above-described embodiment, ring-shaped inductors 100 is to arrange near electrochemical capacitor 200.Be appreciated that in other embodiments, electrochemical capacitor 200 also can replace with other can fixedly secure the device on printed circuit board (PCB) 10.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
