Description

Printed circuit board assembly and apparatus for processing printed circuit board

Technical Field

The present disclosure relates to a printed circuit board assembly and an apparatus for processing a printed circuit board using the same, and more particularly, to a printed circuit board assembly capable of preventing a reverse insertion of a printed circuit board and an apparatus for processing a printed circuit board using the same and provided with the same.

Background

Printed Circuit Boards (PCBs) are used to mount components of electronic devices. Such a printed circuit board is manufactured by: a conductive film is attached to an insulating layer on the board, and then the conductive film is etched in a predetermined pattern to constitute a predetermined wiring required for mounting a component on the insulating layer.

Printed circuit boards have various sizes depending on the type of electronic device in which the printed circuit board is used. For example, a printed circuit board of a protection circuit module for a battery cell has a small size to be received in a case of the battery cell.

When a printed circuit board having such a small size is separately manufactured, mass production is difficult. Therefore, a plurality of lines are formed on a large-sized motherboard, and slits for separation are formed between the plurality of lines to manufacture a plurality of printed circuit boards.

The manufactured printed circuit boards are seated on a jig without being separated from a mother board so that various components are mounted thereon, and when the components are completely mounted, the printed circuit boards are divided into separate units and mounted on a plurality of electronic devices, respectively.

The mother board formed with the plurality of printed circuit boards may have an overall shape symmetrical in the front-rear and left-right directions. Therefore, when the mother substrate is seated on the jig, the mother substrate is easily inverted, and it is difficult for a worker to check the inversion of the mother substrate.

However, the wirings formed on the plurality of printed circuit boards may be asymmetrical in the front-rear, left-right directions. Therefore, when the mother board is vertically inverted or inverted in the left-right direction to sit on the jig, there are limitations as follows: the positions of the wires are changed and the components are not separately mounted at the correct positions on the printed circuit board. Therefore, when the mother board is seated on the jig, it is necessary to check and prevent the inversion of the mother board.

A technique as a background of the present disclosure is disclosed in the following patent documents.

Fig. 1 is a schematic view illustrating a printed circuit board assembly and an apparatus for processing a printed circuit board according to an exemplary embodiment, and fig. 2 is a schematic view illustrating a state in which the printed circuit board assembly is seated on a jig part according to an exemplary embodiment.

Referring to fig. 1 and 2, an apparatus 100 for processing a printed circuit board according to an exemplary embodiment includes a printed circuit board assembly 110 and a jig part 120.

The printed circuit board assembly 110 includes a plurality of printed circuit boards PCB, a plurality of

guide bars

111 and 112, and a plurality of

jig holes

114 and 115. Here, the printed circuit board assembly 110 further includes a plurality of rupture members 113.

In addition, the clamp portion 120 includes a base plate 121 and a plurality of

clamp pins

122 and 123.

1. Printed circuit board assembly (110)

The printed circuit board assembly 110 may be a predetermined board manufactured by forming an insulating layer and a plurality of wires on a motherboard and forming a plurality of slits dividing the motherboard along a circumference of each of the plurality of wires. Of course, the method used to manufacture the printed circuit board assembly 110 may vary. The printed circuit board assembly 110 may be a predetermined board as follows: in the predetermined board, a process of mounting a plurality of electronic components on a wiring is in progress, or the process has been completed.

The printed circuit board assembly 110 may include: a plurality of printed circuit boards PCB extending in one direction X and arranged in another direction Y; a plurality of

guide bars

111 and 112, the plurality of

guide bars

111 and 112 connecting both ends of the plurality of printed circuit boards PCB with respect to each other; and a plurality of

jig holes

114 and 115, the plurality of

jig holes

114 and 115 passing through a plurality of positions spaced apart from each other in the other direction Y along the plurality of

guide rods

111 and 112. The overall shape of the printed circuit board assembly 110 may be, for example, a rectangular plate shape.

The printed circuit board assembly 110 may be disposed on the jig portion 120. The printed circuit board assembly 110 may be seated on the jig portion 120 in a state where the printed circuit board is not inverted in the front-rear and left-right directions, i.e., normally disposed. The front-back inversion means that the printed circuit board assembly is rotated about an axis in the left-right direction such that the top and bottom surfaces of the printed circuit board are inverted. The left-right inversion means that the printed circuit board assembly is rotated about an axis in the front-rear direction such that the top and bottom surfaces of the printed circuit board are inverted. Hereinafter, when it is not necessary to distinguish the front-back inversion and the left-right inversion from each other, the front-back inversion and the left-right inversion are collectively referred to as the inversion.

In a state where the printed circuit board assembly 110 is seated on the jig portion 120, a plurality of electronic components may be mounted at predetermined positions on the top surfaces of a plurality of printed circuit boards PCB provided in the printed circuit board assembly 110. The mounted plurality of electronic components may be connected to traces on a printed circuit board PCB.

The printed circuit board assembly 110 mounted with the electronic components may be separated from the jig part 120 and transferred to a separate board dividing apparatus (not shown). The printed circuit board assembly 110 may be manufactured as a plurality of unit printed circuit boards by being divided along the slit portions by the board dividing means.

The manufactured plurality of unit printed circuit boards may be used to manufacture the battery management system BMS in a subsequent process of manufacturing the battery pack.

2. Printed Circuit Board (PCB)

The printed circuit board PCB may be disposed between the plurality of guide bars 111 and 112. The printed circuit board PCB may be formed in a rectangular plate shape such that the length of the printed circuit board PCB extending in one direction X is greater than the length extending in the other direction Y. Here, one direction X may be, for example, a left-right direction. The other direction Y may be, for example, a front-rear direction. In addition, the printed circuit board PCB may have a predetermined thickness in the vertical direction Z. The printed circuit board PCB may be provided with predetermined lines on a surface of the printed circuit board PCB.

The printed circuit board PCB may be provided in plurality. For example, the number of printed circuit boards PCB may be ten. Of course, the number of printed circuit boards PCB may be variously changed. In addition, one printed circuit board PCB may be disposed between the plurality of guide bars 111 and 112. The plurality of printed circuit boards PCB may be arranged in the other direction Y and spaced apart from each other in the other direction Y. That is, each of the slits may be defined between a plurality of printed circuit boards PCB. In addition, a plurality of printed circuit boards PCB may be respectively connected to the plurality of guide bars 111 and 112 in one direction X. Accordingly, since the plurality of guide bars 111 and 112 constrain the plurality of printed circuit boards PCB to each other, the plurality of printed circuit boards PCB may move together.

3. Guide rod (111, 112)

The guide bars 111 and 112 serve to connect a plurality of printed circuit boards PCB to each other such that the printed circuit boards PCB are simultaneously moved together. That is, the plurality of printed circuit boards PCB may be moved as a whole by the guide bars 111 and 112.

The

guide rods

111 and 112 may include a first guide rod 111 and a second guide rod 112. That is, the

guide rods

111 and 112 may be provided in plurality. Here, the first guide rod 111 may be referred to as a left guide rod, and the second guide rod 112 may be referred to as a right guide rod.

Guide rods

111 and 112 may be spaced apart from each other in one direction and extend in the other direction.

The first guide bar 111 may be connected to one end portion, for example, a left end portion, of the plurality of printed circuit boards PCB, and the second guide bar 112 may be connected to the other end portion, for example, a right end portion, of the plurality of printed circuit boards PCB. Here, the guide bars 111 and 112 and the plurality of printed circuit boards PCB may be spaced apart from each other at a predetermined interval in one direction X, and a plurality of rupture members 113 may be disposed in the spaced gaps.

4. Rupture member (113)

The rupture member 113 may be provided in plurality. The rupture member 113 may connect a plurality of printed circuit boards PCB to the first and second guide bars 111 and 112. That is, a left breaking member may be provided between the left end portions of the plurality of printed circuit boards PCB and the first guide bar 112, and a right breaking member may be provided between the right end portions of the plurality of printed circuit boards PCB and the second guide bar 112.

The rupture member 113 may rupture when the printed circuit board assembly 110 is divided, and the rupture member 113 may have a predetermined strength and a predetermined thickness to stably couple the plurality of printed circuit boards PCB to the guide bars 111 and 112 before the printed circuit board assembly 110 is divided. The rupture member 113 may be made of the same material as the

guide rods

111 and 112. Of course, the material of the rupture member 113 may be different.

5. Clamp hole (114, 115)

The jig holes 114 and 115 may be provided in plurality. The plurality of jig holes 114 and 115 may pass through a plurality of locations spaced apart in the other direction along each of the plurality of

guide rods

111 and 112. The jig pins 122 and 123, which will be described later, are inserted into the jig holes 114 and 115 and coupled to the jig holes 114 and 115, thereby stably seating and fixing the printed circuit board assembly 110 on the jig portion 120.

(1) Arrangement structure of clamp holes

The plurality of clamp holes 114 and 115 may be defined at the following locations: a first position and a second position sequentially spaced apart from one end of the first guide rod 111 in the other direction, a third position and a fourth position sequentially spaced apart from the other end of the first guide rod 111 in the other direction Y, a fifth position and a sixth position sequentially spaced apart from one end of the second guide rod 112 in the other direction Y, and a seventh position and an eighth position sequentially spaced apart from the other end of the second guide rod 112 in the other direction Y. That is, four

jig holes

114 and 115 may be defined in each of the plurality of

guide rods

111 and 112, and thus a total of eight jig holes may be defined.

Here, one end of the first guide rod 111 may be a front end, and the other end may be a rear end. Likewise, one end portion of the second guide rod 112 may be a front end portion, and the other end portion may be a rear end portion. Here, the front-rear direction may be a front-rear direction when the first guide rod 111 is a left guide rod and the second guide rod 112 is a right guide rod.

That is, two jig holes may be defined near the front end portion of the first guide rod 111, and two jig holes may be defined near the rear end portion of the first guide rod 111. The four jig holes may be referred to as a left-first jig hole, a left-second jig hole, a left-third jig hole, and a left-fourth jig hole in order from the jig hole near the front end portion of the first guide rod 111 to the jig hole far from the front end portion of the first guide rod 111. Here, the left-first jig hole and the left-fourth jig hole may be collectively referred to as a left outer jig hole, and the left-second jig hole and the left-third jig hole may be collectively referred to as a left inner jig hole.

Likewise, two jig holes may be defined near the front end portion of the second guide rod 112, and two jig holes may be defined near the rear end portion of the second guide rod 112. The four jig holes may be referred to as a right-first jig hole, a right-second jig hole, a right-third jig hole, and a right-fourth jig hole in order from the jig hole near the front end portion of the second guide rod 112 to the jig hole far from the front end portion of the second guide rod 112. Here, the right-first jig hole and the right-fourth jig hole may be collectively referred to as a right outer jig hole, and the right-second jig hole and the right-third jig hole may be collectively referred to as a right inner jig hole.

(2) Number of clamp holes

As described above, the number of jig holes defined in one guide rod may be four. Thus, the printed circuit board assembly 110 may have a total of eight jig holes.

If the number of jig holes defined in one guide rod exceeds four, the strength of the guide rod may be weaker than a desired predetermined strength, and thus the guide rod may be easily bent. In addition, the width of the portion of the guide rod where the jig hole is defined may be smaller than the width of each of the other portions of the guide rod, and since the internal force of the guide rod is concentrated on the portion where the width of the guide rod is reduced as described above, the strength may be weakened. Therefore, as the number of jig holes increases, the portion of the strength that is weakened may also increase. Therefore, when the number of the jig holes exceeds four, the strength of the guide rod may be weakened as a whole.

When the number of jig holes defined in one guide bar is less than four, the distance between the jig holes may increase and the printed circuit board assembly 110 may be seated on the jig part 120. When the jig pin is inserted into the jig hole, it is difficult for the jig pin to stably fix the entire area of the guide rod. Therefore, among the printed circuit boards connected to the guide bar, the printed circuit board far from the jig hole may be shaken while mounting the electronic components.

(3) Shape of the clamp hole

The penetrating shape of the plurality of jig holes 114 and 115 may be provided in plurality. That is, among the plurality of jig holes 114, 115, the penetrating shape of the predetermined reference jig hole may be different from the penetrating shape of each of the other jig holes.

Accordingly, when the printed circuit board assembly 110 is inverted, the plurality of jig holes 114 and 115 of the inverted printed circuit board assembly 110 and the plurality of jig holes 114 and 115 of the non-inverted printed circuit board assembly 110 may not be symmetrical to each other.

Therefore, even when the printed circuit board assembly 110 attempts to be seated on the jig part 120 in the inverted state, it is possible to prevent the plurality of jig pins 122 and 123, which will be described later, from being inserted into the plurality of jig holes 114 and 115 of the inverted printed circuit board assembly 110, and to prevent the printed circuit board assembly 110 in the inverted state from being seated on the jig part 120.

The penetrating shape of each of the plurality of jig holes 114 and 115 may include a circular shape and a rectangular shape. In addition, the number of jig holes having a circular penetration shape may be greater than the number of jig holes having a rectangular penetration shape.

Here, the penetrating shape refers to a shape in which the guide rod is penetrated by the jig hole. For example, when the guide rod is viewed from the upper side downward, the shape of the jig hole defined in the guide rod is referred to as a penetrating shape. On the other hand, the penetrating shape of the jig hole may be referred to as a cross-sectional shape of the jig hole. Here, the cross section means a horizontal cross section.

In the plurality of jig holes 114, 115, the penetrating shape of the reference jig hole may be a rectangular shape, and the penetrating shape of each of the other jig holes may be a circular shape. Here, the jig hole having a penetrating shape defined in a rectangular shape is classified as the inverted insertion preventing hole 115, and each of the other jig holes is classified as the assembly bonding hole 114.

The position where the inverted insertion preventing hole 115 is defined may vary. For example, as shown in the drawings, the right-third jig hole may be defined as the inverted insertion preventing hole 15, and each of the other jig holes may be defined as the assembly coupling hole 114. That is, one selected from the left and right inner jig holes may be the inverted insertion preventing hole 115. In other words, the inverted insertion prevention hole 115 may be defined at the second position, the fourth position, the sixth position, or the eighth position. As described above, since the inverted insertion preventing hole 115 is defined at a position distant from each of the front and rear ends of the

guide rods

111 and 112, the assembly coupling hole 114 may be defined at a position close to each of the front and rear ends of the

guide rods

111 and 112. Accordingly, the printed circuit board assembly 110 may be stably seated and fixed on the jig part 120.

The plurality of clamp holes 114 and 115 may have various penetrating shapes: as long as the penetrating shape of a predetermined reference jig hole among the plurality of jig holes 114 and 115 and the penetrating shape of each of the other jig holes except the reference jig hole are different from each other. For example, the penetrating shape of the reference jig hole of the plurality of jig holes 114, 115 may be a triangular shape, and the penetrating shape of each of the other jig holes may have a rectangular shape.

(4) Size of the clamp hole

The rectangular shape may be a square shape. Diagonal length D of rectangular shape ₁₁₅ May be larger than the diameter D of the circular shape ₁₁₄ . In addition, the length D of one side of the rectangular shape _115-1 May be smaller than the diameter D of the circular shape ₁₁₄ . In this case, when the rectangular shape and the circular shape overlap, an edge portion of the rectangular shape and an edge portion of the circular shape may overlap each other. The effects produced thereby will be described below, as well as a description of the operation of the apparatus 100 for processing a printed circuit board.

6. Clamp part (120)

The clamp portion 120 includes: a base plate 121, the base plate 121 configured for seating the printed circuit board assembly 110; and a plurality of jig pins 122 and 123, the plurality of jig pins 122 and 123 protruding upward from the base plate 121 so as to be inserted into the plurality of jig holes 114 and 115, respectively. The jig part 120 serves to support the printed circuit board assembly 110 when the jig part 120 performs a process of mounting a plurality of electronic components on the lines of a plurality of printed circuit boards PCBs provided in the printed circuit board assembly 110.

7. Base plate (121)

The substrate 121 may have a top surface with a predetermined area. The surface area of the top surface of the substrate 121 may be greater than the total surface area of the bottom surface of the printed circuit board assembly 110. Accordingly, the printed circuit board assembly 110 may be stably seated at the central portion of the top surface of the substrate 121. Here, the printed circuit board assembly 110 may be disposed to be spaced apart from an edge of the top surface of the substrate 121.

8. Clamp pin (122, 123)

The clamp pins 122 and 123 may be provided in plurality. Here, the number of the jig pins 122 and 123 may be the same as the number of the jig holes 114 and 115.

When the printed circuit board assembly 110 is seated at the central portion of the top surface of the base plate 121, the plurality of jig pins 122 may be disposed at positions that can be inserted into the plurality of jig holes 114 and 115.

For example, when the printed circuit board assembly 110 is disposed above the base plate 121 and aligned in the vertical direction Z, the plurality of jig pins 122 and 123 may be respectively defined at the following positions: a ninth position directly below the left-first jig hole, a tenth position directly below the left-second jig hole, an eleventh position directly below the left-fourth jig hole, a twelfth position directly below the left-third jig hole, a thirteenth position directly below the right-first jig hole, a fourteenth position directly below the right-second jig hole, a fifteenth position directly below the right-fourth jig hole, and a sixteenth position corresponding to the right-third jig hole.

Here, the four chuck pins disposed at the left side portion of the top surface of the substrate 121 may be sequentially referred to as a left-first chuck pin, a left-second chuck pin, a left-third chuck pin, and a left-fourth chuck pin from a front portion of the left side portion of the top surface of the substrate 121 to a rear portion of the left side portion of the top surface of the substrate 121. Here, the left-first jig pin and the left-fourth jig pin may be collectively referred to as a left outer jig pin, and the left-second jig pin and the left-third jig pin may be collectively referred to as a left inner jig pin.

Similarly, the four chuck pins disposed at the right side portion of the top surface of the substrate 121 may be sequentially referred to as a right-first chuck pin, a right-second chuck pin, a right-third chuck pin, and a right-fourth chuck pin from a front portion of the right side portion of the top surface of the substrate 121 to a rear portion of the right side portion of the top surface of the substrate 121. Here, the right-first jig pin and the right-fourth jig pin may be collectively referred to as a right outer jig pin, and the right-second jig pin and the right-third jig pin may be collectively referred to as a right inner jig pin.

A cross-sectional shape of a predetermined reference jig pin among the plurality of jig pins 122 and 123 may have the same shape as a penetrating shape of the inverted insertion preventing hole 115, and a cross-sectional shape of each of the other jig pins may have the same shape as a penetrating shape of the assembly coupling hole 114. Here, the cross-sectional shape refers to a shape of a horizontal cross-section.

A predetermined reference jig pin having the same cross-sectional shape as the penetrating shape of the inverse insertion preventing hole 115 may be classified as the inverse insertion preventing pin 122, and a jig pin having the same cross-sectional shape as the penetrating shape of the assembly coupling hole 114 may be classified as the assembly coupling pin 123.

The reverse insertion preventing pin 122 may be disposed at the sixteenth position described above, and the assembly coupling pin 123 may be disposed at the ninth to fifteenth positions described above.

Here, since the printed circuit board assembly 110 is disposed on the jig portion 120 in a state where the printed circuit board assembly 110 is not inverted and vertically aligned at the central portion of the top surface of the base plate 121, the sixteenth position may be a position directly below the inverted insertion preventing hole 115.

Diagonal length D of top surface of inverted insertion prevention pin 122 ₁₂₃ Diagonal length D of penetrating cross section of insertion preventing hole 115 which can be inverted ₁₁₅ The same is true. In addition, the length D of one side of the top surface of the inverted insertion preventing pin 122 _123-1 Length D of one side of the penetrating cross-section that can be inserted into the inverted insertion preventing hole 115 _115-1 The same is true. In addition, the diameter D of the top surface of the assembly dowel pin 122 ₁₂₂ Diameter D of a penetrating cross-section of the assembly coupling hole 114 ₁₁₄ The same is true.

9. Operation of an apparatus (100) for processing printed circuit boards

Fig. 3 is a schematic view illustrating a state in which the printed circuit board assembly is prevented from being seated on the jig portion when inverted in the left-right direction according to an exemplary embodiment. Fig. 4 is a schematic view illustrating a state in which the printed circuit board assembly is prevented from being seated on the jig part when being inverted in the front-rear direction according to an exemplary embodiment.

Referring to fig. 3, when the printed circuit board assembly 110 is inverted in the left-right direction, the positions of the inverted insertion preventing holes 115 are switched from the right rear side to the left rear side on the top surface of the substrate 121.

Accordingly, when the printed circuit board assembly 110 is lowered, the inverse insertion preventing hole 115 may contact the assembly coupling pin 122 disposed at the left rear side portion of the base plate 121 to prevent the assembly coupling pin 122 from being inserted, thereby preventing the printed circuit board assembly 110 from being seated on the base plate 121 in an inverted state in the left-right direction.

Referring to fig. 4, when the printed circuit board assembly 110 is inverted in the front-rear direction, the position of the inverted insertion preventing hole 115 is switched from the rear right side to the front right side on the top surface of the base plate 121.

Accordingly, when the printed circuit board assembly 110 is lowered, the inverse insertion prevention hole 115 may contact the assembly coupling pin 122 disposed at the right front side portion of the base plate 121 to prevent the assembly coupling pin 122 from being inserted, thereby preventing the printed circuit board assembly 110 from being seated on the base plate 121 in an inverted state in the front-rear direction.

Diagonal length D of penetrating cross-section of hole 115 due to inverted insertion ₁₁₅ And a diagonal length D of the rectangular shape of the top surface of the reverse insertion preventing pin 123 ₁₂₃ Is larger than the diameter D of the penetrating cross section of the assembly coupling hole 114 ₁₁₄ And a diameter D of the circular shape of the top surface of the assembly dowel pin 122 ₁₂₂ And the side length D of the penetrating cross-section of the inverted insertion preventing hole 115 _115-1 And a side length D of the rectangular shape of the top surface of the inverted insertion preventing pin 123 _123-1 Is smaller than the diameter D of the penetrating cross-section of the assembly bonding hole 114 ₁₁₄ And a diameter D of the circular shape of the top surface of the assembly dowel pin 122 ₁₂₂ Can be prevented from being inserted into the reverse insertion preventing hole 115, and can also be prevented from being inserted into the assembly combining hole 114. That is, in this case, when the rectangular shape and the circular shape are overlapped, the edge portion of the rectangular shape and the edge portion of the circular shape may overlap each other to prevent the insertion of the assembly coupling pin 122 into the inverted insertion preventing hole 115 and to prevent the insertion of the insertion preventing pin 123 into the assembly coupling hole 114.

Accordingly, in a state where the printed circuit board assembly 110 is inverted, the printed circuit board assembly 110 and the jig portion 120 may contact each other at two positions to prevent the printed circuit board assembly 110 from being seated in place. Accordingly, it is possible to suppress or prevent the printed circuit board assembly 110 from being inclined in a state where the printed circuit board assembly 110 is spaced apart from the top surface of the substrate 121 by the protruding height of each of the jig pins. Accordingly, the printed circuit board assembly 110 may be prevented from being damaged.

10. Apparatus (200) for processing printed circuit board according to comparative example

Fig. 5 is a schematic diagram illustrating a printed circuit board assembly and an apparatus for processing a printed circuit board according to a comparative example.

Referring to fig. 5, the printed circuit board assembly 210 according to the comparative example has the following structure: in this structure, the number of each of the jig holes and the jig pins is increased by one to prevent the printed circuit board assembly 210 from being inverted in the left-right direction and in the front-rear direction, without providing the inverted insertion preventing holes and the inverted insertion preventing pins.

The printed circuit board assembly 210 includes one clamp hole 214 in addition to four clamp holes 214 in the left guide bar 211 and one clamp hole 214 in addition to four clamp holes 214 in the right guide bar 212. Here, the arrangement of the jig holes of the left guide bar 211 and the arrangement of the jig holes of the right guide bar 212 are different from each other, and the arrangement of the jig pins 222 provided on the top surface of the substrate 221 of the jig portion 220 corresponds to the arrangement of the jig holes to prevent the printed circuit board assembly 210 from being inserted upside down in the left-right direction.

Reference numeral "213" not described above denotes a rupture member of the printed circuit board assembly 210 according to the comparative example.

11. Comparison of a printed circuit board assembly (210) according to a comparative example with a printed circuit board assembly (110) according to an exemplary embodiment

Fig. 6 (a) and (b) are schematic views for explaining a comparison of bent states of the printed circuit board assembly according to the exemplary embodiment and the printed circuit board assembly according to the comparative example.

Referring to fig. 6, when the printed circuit board assembly 110 according to the exemplary embodiment receives a force in the front-rear direction, the internal force is concentrated only at eight positions P where the jig holes are provided ₁₁ To P ₄₂ And thus the printed circuit board assembly 110 may strongly resist bending.

However, when the printed circuit board assembly 210 according to the comparative example receives a force in the front-rear direction, the internal force is concentrated on the ten positions P where the jig holes are provided ₅₁ To P ₉₂ And thus, it is difficult for the printed circuit board assembly 210 to strongly resist bending. Therefore, the printed circuit board assembly 210 according to the comparative example is more easily bent than the printed circuit board assembly 110 according to the exemplary embodiment.

In addition, in the manufacture of the printed circuit board assembly, as the number of jig holes increases, since time taken to perform the manufacturing process increases and costs increase, the printed circuit board assembly 210 according to the comparative example may be more easily bent than the printed circuit board assembly 110 according to the exemplary embodiment, and may also be disadvantageous in terms of manufacture compared to the printed circuit board assembly 110 according to the exemplary embodiment.

According to an exemplary embodiment, a plurality of jig holes may be provided in two guide bars in which a plurality of printed circuit boards are mounted, and a penetrating shape of one jig hole of the plurality of jig holes may be different from a penetrating shape of each of the other jig holes of the plurality of jig holes, and thus, when the printed circuit board assembly is inverted, positions of jig holes having different shapes may also be inverted. Therefore, when the inverted printed circuit board assembly is seated on the jig part provided with the plurality of jig pins, the inverted jig holes having different shapes may not be coupled with the jig pins provided at the corresponding positions, thereby preventing the printed circuit board assembly from being seated in the jig part in the inverted state.

Although the setting apparatus and method have been described with reference to specific embodiments, the setting apparatus and method are not limited thereto. It should be noted that the configurations and methods disclosed in the above-described embodiments of the present invention may be combined and modified in various forms by combining or interchanging the configurations and methods with each other, and modifications of the configurations and methods may also be regarded as the scope of the present invention. Accordingly, it will be readily understood by those skilled in the art that various modifications and changes may be made to the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
