Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for correcting a pin of an electronic component, and more particularly to a jig for correcting a pin deformed during solder plating so that the pin has a predetermined positional relationship.

[0002]

2. Description of the Related Art For example, after assembling is completed, an electronic component such as an IC is solder-plated on a plurality of linear pins drawn from the electronic component so as to be mounted as one component on a printed circuit board. Need to be formed. The formation of the solder plating is performed by immersing the pins of the electronic component in the solder dip layer.

[0003] Here, as shown in FIG.
During such solder plating, the pins 12 pulled out from the electronic component body 11 receive unnecessary force, and thus are easily deformed. If the pins 12 are deformed in this manner, the electronic components 10 cannot be aligned to a predetermined position when the electronic component 10 is mounted on a printed circuit board, which affects soldering. Therefore, the pins 12 are modified so that the pins 12 have a predetermined positional relationship in advance. It is necessary to keep. Conventionally, such a pin 1
The correction of No. 2 is performed using a sleeve type correction jig.

[0004]

By the way, in the pin correction using the conventional sleeve-type correction jig, the correction range cannot be corrected if the pin correction range is narrow and the deformation is slightly increased. Or there was a problem that it was difficult. Further, according to the sleeve type correction jig, there is a problem that workability is deteriorated because clogging of solder chips and the like is apt to occur.

[0005] That is, since the conventional correction jig of the sleeve type is used, it is difficult to widen the correction range of the pin, and clogging of solder scraps and the like which occur at the time of correction cannot be avoided.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and has as its object to widen a pin correction range and prevent workability from being reduced by solder chips.

[0007]

According to a first aspect of the present invention, there is provided a pin correcting jig for an electronic component, comprising: a first unit having a plurality of V-shaped grooves corresponding to pins; A second unit in which a V-shaped groove is provided at the front edge, and the two units are relatively moved in a direction approaching each other so as to oppose each other when the front edges are viewed from above. The V-shaped groove allows a rectangular gap to be created and overlapped so that the gap becomes gradually smaller,
It is characterized in that the pin is corrected by sandwiching the pin between the two V-shaped grooves.

Therefore, according to the present invention, the pin can be corrected by separating the first and second units and moving one of the units relative to the other to sandwich the unit between the opposed V-shaped grooves. As a result, even a pin that has undergone a considerable deformation can be corrected, and the correction range can be expanded.
Further, since there is no possibility of clogging due to the solder dust, there is no possibility that the workability is reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is based on the principle that a plurality of pins, which are drawn out in parallel from a part of a main body of an electronic component, such as an IC, which is located on a straight line, have a predetermined positional relationship. A jig for correcting a pin of an electronic component to be corrected, comprising: a first unit having a plurality of V-shaped grooves corresponding to the pins disposed at a front edge; and a plurality of V-shaped faces facing the V-shaped groove. A second unit having a groove disposed at a front edge thereof, and by moving at least one of the first and second units relatively to the other side, the front edges are viewed from above. The two V-shaped grooves facing each other form a rectangular gap and can be overlapped so that the gap is gradually reduced. The straightening is performed by sandwiching the pin between the two V-shaped grooves. And the first The second unit may such material be even or wood made of a resin may be made of metal it is not particularly limited.

In the above-described configuration, recesses having different heights are provided on the front edge surfaces of both units, and when each unit is moved in a direction approaching each other, each recess is replaced with a non-concave portion on the other side. When the portions are fitted to each other, the first and second units 2 and 3 make it easier to define the direction of the pin perpendicular to the pin formation surface.

With the pin 12 positioned in each of the V-shaped grooves 4 and 5, the pin 12 is sandwiched. Since the height H of the first and second units 2 and 3 is set so as to contact most of the length L of the pin 12, the pin 12 deformed at the time of solder plating by the pinching operation is solder plated. It is easily corrected in combination with the residual heat at the time. Subsequently, the first and second units 2,
