Embodiment
In order to facilitate the understanding of those skilled in the art, below in conjunction with attached drawing and embodiment to the utility model into traveling
One step is described in detail.
Embodiment one
Please refer to Fig.1 and Fig. 2, a kind of reflow soldering gauge for the asymmetric component of pin, including carrier 2 and pressure
Circuit board pressing to be welded is fixed on carrier 2 by bar 1, the press strip 1；It is fixed that the press strip 1 is provided below multiple first
Position groove 12, the carrier 2 are provided with multiple second locating slots 23 above, and it is not right that first locating slot 12 is used for pin to be welded
Claim the positioning of component, second locating slot 23 is used for the positioning of pcb board, 12 and second locating slot 23 of the first locating slot
Position is adapted.By the first locating slot 12 for being mutually adapted and the second locating slot 23 by pin asymmetry component to be welded and
PCB is positioned, and by the tin cream adhesion being pre-printed on PCB pads between PCB and pin asymmetry component to be welded, then is led to
The gravity pressing for crossing press strip 1 is fixed, and when being welded by reflow ovens, pin asymmetry component to be welded is due to the pressure of press strip 1
Effect and the limitation of the first locating slot 12, will not produce bad phenomenon that is uneven, upwarping.
Please refer to Fig.1 and Fig. 2, be provided with multiple location holes 111 on press strip 1, multiple positioning columns are provided with the carrier 2
21, the location hole 111 matches with 21 position of positioning column and size.So press strip 1 and carrier 2 by location hole 111 and are determined
Position column positioning, so that avoiding the occurrence of press strip 1 and misplacing with carrier 2 causes the weldering of pin asymmetry component pin and PCB to be welded
Intertwining position, and then cause failure welding.Preferably, fixing device 11 is provided at both ends with below press strip 1, each fixed dress
Put and a location hole 111 is provided with 11；By set fixing device 11 avoid press strip 1 to accomplish it is very thick could be with carrier 2
Pressing, both waste of materials or had been not convenient to use.Location hole 111 and positioning column 21 are both provided with magnet, and location hole 111 and positioning
The magnetic pole opposite when being engaged of column 21 is different, i.e., a magnet is set in location hole 111, a magnet is set on positioning column 21,
Two opposite magnetic poles of magnet are different；Adapter to be welded is not only pressed in by the pressure of press strip itself when press strip 1 and gauge 2 coordinate
On foot asymmetry component, pin asymmetry component to be welded is further also pressed on by the suction of two magnet by PCB
On, pressing is more reliable.
Please refer to Fig.1 and Fig. 2, carrier 2 are provided with multiple heat emission holes 22, so that the gauge of the utility model is in excessively complete reflux
When furnace temperature is higher, it can realize that upper and lower cross-ventilation accelerates the heat dissipation of gauge entirety by heat emission hole 22, quickly cooling
To the normal temperature state that can single-handedly take.
Please refer to Fig.1 and Fig. 2, the surrounding at the front of carrier 2 or the back side, which is provided with, strengthens frame 24, is preferably the reinforcement
Frame 24 is integrally formed with carrier 2；Because consider in production production capacity needs carrier may be done it is bigger once may be used
With the more circuit boards of reflow soldering, carrier is bigger to may result in integral strength decline, carries inconvenience, increases around carrier 2
Strengthen frame 24 can play the role of strengthen intensity, be integrally formed it is more convenient, particularly casting when.
Consider that temperature is higher in reflow ovens, the gauge that general steel make easily is aoxidized and causes intensity to drop at high temperature
Low, abnormal appearance, therefore preferably carrier 2 and press strip 1 are made with resistance to oxidation steel.
During work, first in the second locating slot of carrier 2（23）Pcb board is piled, then the print solder paste on the pad of PCB,
Again by pin asymmetry component patch to be welded to correspondence position, press strip is put in correspondence position, crosses Reflow Soldering.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
It is exhaustive.All any modification, equivalent and improvement made where within the spirit and principles of the present invention etc., should be included in
Within the protection domain of the utility model claims.
