Meanwhile, when the circuit board 1 and the through-hole reflow device 2 are supported by the support 3 in the thickness direction Z, the contact position between the pins 22 and the circuit board 1 can be centered, the soldering reliability between the through-hole reflow device 2 and the circuit board 1 can be improved, and in addition, the position of the socket 212 (e.g., a TYPEC port of an electronic device) of the through-hole reflow device 2 can be raised, so that the appearance performance of the electronic device can be improved, and the use by a user is facilitated.

Specifically, as shown in the circuit board assembly in fig. 3 and the via reflow device 2 in fig. 4, the leads 22 of the via reflow device 2 include a plurality of first leads 221 and a plurality of second leads 222, and along the thickness direction Z of the circuit board assembly, the size of the first leads 221 is larger than that of the second leads 222, that is, the height of the first leads 221 is larger than that of the second leads 222; the transition part 211 includes a first transition part 211a connected to the first lead 221 and a second transition part 211b connected to the second lead 222, and since the height of the first lead 221 is greater than that of the second lead 222, the height of the first transition part 211a is greater than that of the second transition part 211 b.

At this time, a first supporting member is disposed between the at least two first transition portions 211a and the circuit board 1, and/or a second supporting member is disposed between the at least two second transition portions 211b and the circuit board 1, the thicknesses of the first supporting members are the same, the thicknesses of the second supporting members are the same, and the thickness of the first supporting member is greater than the thickness of the second supporting member, so that the main body 21 is parallel to the circuit board 1.

As shown in fig. 4, in the through hole reflow device 2, the through hole reflow device 2 includes two first pins 221 and two second pins 222, and correspondingly, includes two first transition portions 211a and two second transition portions 211b, and a support 3 with the same thickness is disposed between the two second transition portions 211b and the circuit board 1, so that the through hole reflow device 2 is raised by the thickness of the support 3. In addition, the first pin 221 and the second pin 222 are arranged side by side, so that the first transition portion 211a is located above the second transition portion 211b, when the through hole reflow device 2 is soldered to the circuit board 1, as shown in fig. 1, the adjacent first pin 221 and the second pin 222 are located in the same through hole 11, and at this time, the circuit board 1 only needs to be provided with two through holes 11 soldered to the through hole reflow device 2. Or, each pin 22 of the through hole reflow device 2 may be staggered, so that the first transition portion 211a and the second transition portion 211b are staggered, when the through hole reflow device 2 is soldered to the circuit board 1, the circuit board 1 needs to be provided with four through holes 11, and the four pins 22 respectively extend into the corresponding through holes 11, thereby realizing soldering.

In another embodiment, fig. 5 and 6 show a schematic structural view of a circuit board assembly in another embodiment, the body portion 21 is arranged obliquely with respect to the circuit board 1 along a plane perpendicular to the thickness direction Z of the circuit board assembly, i.e. after arranging the support 3, the pins 22 of the via reflow device 2 are raised, so that the pins 22 of larger size can still be used for circuit boards 1 of smaller thickness. Meanwhile, a part of the body portion 21 of the through-hole reflow device 2 is raised and the other part is not raised, or each position of the body portion 21 of the through-hole reflow device 2 is raised and the raised heights of the positions are different, so that the body portion 21 is inclined with respect to the circuit board 1 after the raising, and at this time, the relative positions of the through-hole reflow device 2 and the circuit board 1 are as shown in fig. 7. At this time, a portion of the position of the through-hole reflow device 2 is raised, so that the position of other electronic components connected to the position is also raised, and when the through-hole reflow device 2 has the socket 212, the height of the socket 212 is raised, for example, when the socket 212 is a TYPEC interface of an electronic device, so that the TYPEC interface is raised with respect to the position of the middle frame, thereby facilitating centering of the TYPEC interface, improving the appearance performance of the electronic device, and facilitating the use of a user.

Specifically, as shown in the positional relationship between the through hole reflow device 2 and the circuit board 1 shown in fig. 7, the through hole reflow device 2 is inclined with respect to the circuit board 1, and the inclination angle α is 0.5 ° to 2 °, for example, the inclination angle α may specifically be: 0.5 °, 1 °, 1.5 °, 2 °, etc.

In this embodiment, when the inclination angle α of the through hole reflow device 2 is too large (for example, greater than 2 °), a part of the through hole reflow device 2 is raised too high, that is, the raised height of the pin 22 of the part is too large, and there is a problem that the contact area between the pin 22 and the circuit board 1 is too small, which results in too low connection reliability; when the inclination angle α of the through-hole reflow device 2 is too small (for example, less than 0.5 °), the height at which a part of the through-hole reflow device 2 is raised is too small, and the socket 212 cannot be raised to a predetermined position, resulting in poor appearance performance of the electronic apparatus. Therefore, when the inclination angle α of the through hole reflow device 2 is 0.5 ° to 2 °, the soldering reliability between the pins 22 of the through hole reflow device 2 and the circuit board 1 is high, and a part of the through hole reflow device 2 can be raised to a preset height to meet the user demand.

In a specific embodiment, the body portion 21 includes a plurality of transition portions 211, and a support 3 is disposed between a part of the transition portions 211 and the circuit board 1, and no support 3 is disposed between another part of the transition portions 211 and the circuit board 1, so as to incline the through hole reflow device 2; alternatively, a support 3 is disposed between each transition portion 211 and the circuit board 1, and at least some of the supports 3 have different heights, so as to incline the through hole reflow device 2.

The transition part 211 includes a first transition part 211a connected to the first lead 221 and a second transition part 211b connected to the second lead 222, and since the height of the first lead 221 is greater than that of the second lead 222, the height of the first transition part 211a is greater than that of the second transition part 211 b.

At this time, the supporters 3 are disposed between the at least two second transition portions 211b and the circuit board 1, and the supporters 3 are not disposed between the first transition portions 211b and the circuit board 1.

In this embodiment, along the first direction X, the second transition portion 211b is closer to the socket 212 than the first transition portion 211a, so that when the support 3 is disposed between at least two second transition portions 211b and the circuit board 1, the second transition portion 211b is lifted and drives the socket 212 to be lifted, and the first transition portion 211a is not lifted, so that the main body 21 of the through hole reflow device 2 is inclined with respect to the circuit board 1.

In the through hole reflow device 2 shown in fig. 10, the through hole reflow device 2 includes two first pins 221 and two second pins 222, and accordingly includes two first transition portions 211a and two second transition portions 211b, and a support 3 is disposed between each of the two second transition portions 211b and the circuit board 1.
