[0002] PCB circuit board immersion gold process is a commonly used surface treatment technology. It uses chemical deposition method to generate a layer of plating through chemical oxidation-reduction reaction. The thickness is generally thicker. It is a kind of chemical nickel-gold gold layer deposition method, which can achieve a thicker gold layer. It can improve the reliability and corrosion resistance of the circuit board, and also improve the appearance quality of the circuit board. In the process of circuit board manufacturing, the immersion gold process is a very important step. The thickness of immersion gold is generally 1-3Uinch, so the thickness of gold produced by this surface treatment method is generally thicker.

[0003] After the PCB circuit board is processed by the immersion gold process, the thickness of the PCB circuit board needs to be monitored to determine the thickness of the gold layer. At present, the thickness of the PCB circuit board gold layer is usually detected manually, which is troublesome; therefore, the market urgently needs to develop a board thickness detection instrument for the immersion gold wire process to help people solve the existing problems.

In the utility model, through the setting of the vernier caliper measuring device, a measuring scale is fixedly connected between the lower end of the extension plate and the upper end surface of the support platform, and a vernier caliper measuring device is arranged at the lower end of the extension plate. By setting the precise distance between the lower end surface of the detection plate and the upper end surface of the detection platform, the circuit board to be detected is placed on the detection platform, and the threaded rod is driven by the motor to rotate slowly.

When the upper measuring groove of the vernier caliper measuring device is lifted and lowered along the measuring scale, the vernier caliper measuring device will accurately calculate the moving distance. When the vernier caliper measuring device descends, one side of the detection plate contacts the upper end surface of the PCB circuit board, so that the vernier caliper measuring device stops following the movement of the supporting threaded slider. The plate thickness and the precise value can be obtained by subtracting the moving distance measured by the vernier caliper measuring device from the precise distance between the lower end surface of the detection plate and the upper end surface of the detection platform. The operation is simple and convenient.

[0014] 2. In the utility model, through the setting of the supporting threaded slider, the supporting threaded slider is movably connected inside the lifting groove, and the rotation of the threaded rod drives the supporting threaded slider to move up and down in the lifting groove.

[0015] 3. In the utility model, through the setting of the stabilizing rod, a stabilizing rod is fixedly connected to one side of the middle part between the lifting groove and the buffer groove. The middle part of the stabilizing rod passes through the first circular groove on the supporting threaded slider. The stabilizing rod guides the supporting threaded slider when it is lifted or lowered, thereby ensuring the stability of the lifting of the supporting threaded slider.

The upper end of the middle part of the stabilizing rod passes through the second circular groove on the stabilizing member. The stabilizing rod guides the stabilizing member when it is lifted or lowered, thereby ensuring the stability of the lifting of the stabilizing member 403. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Furthermore, a motor slot 102 is provided inside the support platform 1 and at the lower end of the buffer slot 101 , and a motor 103 is provided inside the motor slot 102 .

[0024] Furthermore, the lower end of the threaded rod 202 extends to the inside of the motor slot 102 and is fixedly connected to the output shaft of the motor 103 , and the threaded rod 202 is driven to rotate by the motor 103 .

[0025] Furthermore, the threaded rod 202 is threadedly connected to one side of the middle of the supporting threaded slider 3, and a first circular groove 301 is provided on the other side of the middle of the supporting threaded slider 3. The threaded rod 202 rotates to drive the supporting threaded slider 3 to rise and fall in the lifting groove 201.

[0026] Furthermore, a stabilizing rod 203 is fixedly connected to one side of the middle part between the lifting groove 201 and the buffer groove 101. The middle part of the stabilizing rod 203 passes through the first circular groove 301 on the supporting threaded slider 3. The stabilizing rod 203 guides the supporting threaded slider 3 when it is lifted or lowered, thereby ensuring the stability of the lifting or lowering of the supporting threaded slider 3.

The plate thickness and its accurate value can be obtained by subtracting the moving distance measured by the vernier caliper measuring device 4 from the precise distance between the lower end surface of the detection plate 402 and the upper end surface of the detection table 104.
