Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the anti-tear circuit board of the POS machine comprises a PET film layer 1 and an alarm device 4, and the PET film layer 1 is printed with a trigger circuit 3 for triggering the alarm device 4 by an anti-tear ink layer 2, so The wires of the trigger circuit 3 are in a serpentine direction. The trigger circuit 3 is printed with an insulating layer 6 for isolating the trigger circuit 3. The insulating layer 6 is coated with an adhesive layer 5 that can be pasted on the internal components of the POS machine. The trigger circuit 3 is routed after the PET film layer 1 is torn off. disconnect. The anti-tear ink layer 2 is printed on the surface of the PET film layer 1, the trigger circuit 3 is printed on the surface of the anti-tear ink layer 2, the surface of the trigger circuit 3 is printed with an insulating layer 6 which can be insulating oil, and the insulating layer 6 is coated with an adhesive layer 5, The adhesive layer 5 is pasted on the internal components of the POS machine. To obtain the internal components of the POS machine or disassemble the internal components of the POS machine, the PET film layer 1 needs to be uncovered. Because the anti-tear ink layer 2 is printed, once the PET film layer 1 is uncovered, the trigger circuit 3 is damaged, and the alarm device 4 cannot receive one pulse every 0.2 seconds, and the alarm device 4 is triggered. The internal components of the POS machine are arranged up and down, and the upper and lower ends of the PET film layer 1 can be printed with a trigger circuit 3 for triggering the alarm device 4 through the tear-proof ink layer 2. The upper end of the adhesive layer 5 is pasted with the upper end. The adhesive layer 5 pastes the components at the lower end to prevent the upper and lower components from being disassembled.

As shown in FIG. 1 and FIG. 2 , the anti-tear ink layer 2 is Acheson insulating ink 452SS. Acheson insulating ink 452SS is used for insulation protection of flexible circuit boards, and has good adhesion to treated or untreated PET film. Provides excellent flex resistance to the wire and prevents wear and tear on the plug. Through a large number of field tests, Aitchison insulating ink ED452SS is used as the anti-tear ink layer 2, and the trigger circuit 3 is disconnected after the PET film layer 1 is uncovered.

As shown in Figure 1 and Figure 2, the adhesive layer 5 is pressure-sensitive adhesive. Pressure-sensitive adhesives are adhesives that are sensitive to pressure, and pressure-sensitive adhesives will not degumming during use.

As shown in FIG. 1 and FIG. 2 , the wire width of the trigger circuit 3 and the distance between the wires are not more than 0.2 mm. Wires are full of trigger circuit 3 .

As shown in FIG. 1 and FIG. 2 , the wire width of the trigger circuit 3 and the distance between the wires are 0.15 mm to 0.2 mm. Wires are full of trigger circuit 3 .

As shown in Figure 1 and Figure 2, the manufacturing method of the anti-tear protection circuit board of the internal components of the POS machine, the method includes the following steps: first connect the trigger circuit 3 with the alarm device 4, and the alarm device 4 receives the alarm signal of the trigger circuit 3, It may be that the alarm device 4 receives a pulse every 0.2 seconds. When the trigger circuit 3 is disconnected and the alarm device 4 does not receive a pulse after an interval of more than 0.2 seconds, the alarm device 4 alarms. The PET film layer 1 first prints the anti-tear ink layer 2, and the anti-tear ink layer 2 is printed with a trigger circuit 3 in a serpentine direction, and the trigger circuit 3 is printed with an insulating layer 6 for isolating the trigger circuit 3. The insulating layer 6 is coated with an adhesive layer 5 that can be attached to the internal components of the POS machine. The anti-tear ink layer 2 is Acheson insulating ink 452SS. Acheson insulating ink 452SS is used for insulation protection of flexible circuit boards, and has good adhesion to treated or untreated PET film. Provides excellent flex resistance to the wire and prevents wear and tear on the plug. Through a large number of field tests, Aitchison insulating ink ED452SS is used as the anti-tear ink layer 2, and the trigger circuit 3 is disconnected after the PET film layer 1 is uncovered. The PET film layer 1 is first printed with Acheson insulating ink 452SS, and then printed silver oil with a thickness of 4-6 μm on the Acheson insulating ink 452SS, which is the trigger circuit 3. The baking temperature is 120°C and the baking time is one hour. In order to play an anti-oxidation effect, carbon oil with a thickness of 3-5 μm is printed on the trigger circuit 3, and the baking temperature is 120° C., and the baking time is one hour. In order to play the role of insulation, the insulating oil with a thickness of 5-7μm is printed on the carbon oil, and it is passed through an ultraviolet light curing furnace, and the ultraviolet light intensity is 600mj/cm2. As shown in Fig. 1 and Fig. 2, the adhesive layer 5 is a pressure-sensitive adhesive, and the model may be 3M467. Pressure-sensitive adhesives are pressure-sensitive adhesives, and pressure-sensitive adhesives will not degumming during use. After pasting the pressure-sensitive adhesive on the internal components of the POS machine that need to be protected, wait for 48 hours to fix it to ensure the fixity of the paste. Through this method, when the PET film layer 1 is torn off, the silver oil, that is, the trigger circuit 3 is disconnected at the same time, and the alarm device 4 is triggered to give an alarm.
