[0002] The watch is charged with a charging pin, which corresponds to the insertion hole of the watch bottom case. The circuit board is connected to the inside of the watch bottom case. Since the wiring points on the circuit board are dense and the wiring points on the circuit board are aligned with the insertion holes, high precision requirements are required. Therefore, FPC cables are welded on the circuit board. Its excellent flexible structure can ensure precise installation and can adapt to watches with different shells without changing the circuit board design (only the FPC cable needs to correspond to the watch bottom case).

[0003] As attached Figure 7 As shown, the FPC cable 35 has a positive contact 30, a negative contact 31, a first welding hole 32, and a second welding hole 33, and the mainboard 34 has a negative contact 29 and a positive contact 28. The first welding hole 32 and the second welding hole 33 are arranged corresponding to the negative contact 29 and the positive contact 28 of the mainboard, and are sleeved on the contacts for welding. The positive contact 30 of the FPC cable is in a conductive state with the inside of the first welding hole 32, and the negative contact 31 of the FPC cable is in a conductive state with the second welding hole 33. The inside of the connection hole 33 is in a conducting state. When charging, you only need to touch the positive contact 30 and the negative contact 31 of the FPC cable to charge. When designing, you only need to ensure that the positions of the first welding hole 32 and the second welding hole 33 correspond to the main board 34. Different FPC cables can be designed according to the specific appearance of the watch. The FPC cable is connected to the circuit board by welding. After welding, it is necessary to test whether the welding is normal. For this reason, the utility model proposes a mainboard testing tool. Utility Model Content

The cathodes of the first indicator light 7, the second indicator light 8, and the third indicator light 9 are all connected to the cathode of the power supply, which is a 5V power supply. The anode of the first indicator light 7 is connected to the second test pin 18, the third test pin 19 is connected to the anode of the second indicator light 8, and the first test pin 17 and the fourth test pin 20 are connected to the anode of the power supply;

The first pressure-sensitive element 22 and the second pressure-sensitive element 23 are both connected to the controller 27. When the controller 27 receives signals from the first pressure-sensitive element 22 and the second pressure-sensitive element 23 at the same time, the circuit is controlled to be turned on.

[0042] The specific positions of the first test pin 17, the second test pin 18, the third test pin 19, and the fourth test pin 20 need to be appropriately positioned according to the positive contact 30 of the FPC cable, the negative contact 31 of the FPC cable, the first welding hole 32, and the second welding hole 33, so that they correspond one to one;

[0043] The first test needle 17 and the second test needle 18 are connected as a whole by the second elastic body 26, and they can move up and down synchronously. After the top of the second elastic body 26 is fixed on the upper cover 21, it can also move upward for a distance based on its own elasticity, and can squeeze the first pressure-sensitive element 22 upward. Similarly, the third test needle 19 and the fourth test needle 20 can also squeeze the second pressure-sensitive element 23.

[0044] Reference Figure 6, the power supply is a 5V power supply, the cathodes of the first indicator light 7, the second indicator light 8, and the third indicator light 9 are all connected to the cathode of the power supply, the anode of the first indicator light 7 is connected to the second test pin 18, the third test pin 19 is connected to the anode of the second indicator light 8, the first test pin 17 and the fourth test pin 20 are connected to the anode of the power supply;

[0045] The second test pin 18 is in contact with the first test pin 17 synchronously. If there is no problem with the welding, the first indicator light 7 will light up. Similarly, the second indicator light 8 will also light up. According to the lighting of the first indicator light 7 and the second indicator light 8, it can be judged whether there is a problem with the mainboard welding.

[0046] The positive pole of the third indicator light 9 is connected to the positive pole of the power supply, and a controller 27 is arranged in series in the circuit. The first pressure-sensitive element 22 and the second pressure-sensitive element 23 are both connected to the controller 27. When the controller 27 receives signals from the first pressure-sensitive element 22 and the second pressure-sensitive element 23 at the same time, the circuit is controlled to be turned on, that is, the third indicator light 9 can be turned on.

[0047] The working principle and use process of this utility model:

[0048] When in use, place the motherboard to be tested on the motherboard holder 10, at which time the positive contact 30 of the FPC cable, the negative contact 31 of the FPC cable, the first welding hole 32, the second welding hole 33 and the first test needle 17, the second test needle 18, the third test needle 19, and the fourth test needle 20 are in a corresponding state, and the handle 13 is manually controlled to press down the lower pressing plate 3, so that the first test needle 17, the second test needle 18, the third test needle 19, and the fourth test needle 20 are in contact with the positive contact 30 of the FPC cable, the negative contact 31 of the FPC cable, the first welding hole 32, and the second welding hole 33 respectively;

[0049] After the contact, the second elastic body 26 is compressed, so that the first test needle 17 and the second test needle 18 move upward, and the top squeezes the first pressure-sensitive element 22, and sends a signal to the controller 27. Similarly, if the second test needle 18 and the third test needle 19 are also in a normal state, they will squeeze the second pressure-sensitive element 23 and send a signal to the controller 27. At this time, the controller 27 controls the circuit to be turned on, and the third indicator light 9 lights up, indicating that the above operations are all in a normal state;

[0050] Since the first test pin 17 is in contact with the positive contact 30 of the FPC cable, and the second test pin 18 is in contact with the negative contact 31 of the FPC cable, if the welding is normal, the first test pin 17 and the second test pin 18 are connected, and the first indicator light 7 is on; similarly, according to the third test pin 19 and the fourth test pin 20, the second indicator light can be on;

[0051] The user can judge whether there is any problem in welding according to the lighting conditions of the first indicator light 7, the second indicator light 8 and the third indicator light 9.
