Description

Anti-break type electric closed loop manufacturing method

The present invention relates to a method of fabricating a circuit, and more particularly to a method of fabricating a break-off electrical closed loop.

Touch panels are now used in many electronic devices. With the demand and technology innovation, the convenience brought by touch technology can be found from small to portable electronic devices to large display panels. However, in the manufacturing process of the touch panel, the condition of the sensor connection may be invalid due to many factors, that is, the disconnection or poor contact, thereby affecting the production cost and product function.

For example, as shown in FIG. 1, when a closed sensing circuit 12 is formed on an insulating substrate 10, an open circuit detection is performed first, and if the closed sensing circuit 12 is confirmed to have no open circuit condition, it is further insulated. Other structures are formed on the substrate 10 and the enclosed sensing circuit 12. In the prior art, in order to detect the open circuit condition of the closed sensing circuit 12, a voltage generator 14 and an oscilloscope 16 are provided, and the voltage generator 14 and the oscilloscope 16 are connected to the probe to make any two of the closed sensing circuits 12. The end contacts the probe. When the voltage generator 14 generates a voltage to the closed sensing circuit 12, in theory, if the closed sensing circuit 12 does not have any open circuit, the oscilloscope 16 displays a zero voltage drop. If the closed sensing circuit 12 has an open circuit, the oscilloscope 16 should The voltage waveform generated by the voltage generator 14 is displayed. However, for the closed sensing circuit 12, due to its closed nature, the oscilloscope 16 still displays a zero voltage drop when there is only one open circuit, that is, the open circuit of the closed sensing circuit 12 cannot be detected, resulting in a missed detection.

Therefore, the present invention has been made in view of the above-mentioned problems, and proposes a method of manufacturing a break-proof electrical closed loop to solve the problems caused by the prior art.

The main object of the present invention is to provide a method for manufacturing a break-proof electrical closed loop, which applies a voltage on a loop sensing line corresponding to a position of a breaking opening to detect an open circuit condition, and confirms that the loop sensing line is not open. Filling the open circuit opening to form a complete electrical closed loop, thereby avoiding the open circuit leakage of the electrical closed loop.

To achieve the above object, the present invention provides a method for fabricating a break-off electrical closed loop. First, an insulating substrate is provided having a loop sensing line formed thereon, the loop sensing line having at least one open circuit break. Next, applying a non-zero voltage to the loop sensing line corresponding to the open end of the open circuit to determine whether the loop sensing line is open: if yes, stopping the subsequent step; and if not, filling at least one conductive block in the open circuit break, electrically The loop sensing line is connected and forms an electrical closed loop with the loop sensing line.

The conductive block is made of silver and is formed on the top surface of the loop sensing line. Further, the insulating substrate is a transparent insulating substrate such as a glass substrate.

When the number of open circuit breaks is two, the number of conductive blocks is also two, and the two conductive blocks fill the two open circuit breaks respectively, and the loop sensing line applies a non-zero voltage to the two ends of each open circuit break. Alternatively, when the number of open fractures is plural, the number of conductive blocks is also plural, all conductive blocks fill all open breaks, and the loop sense line applies a non-zero voltage to each of the open ends.

The loop sensing line is connected to a signal display and a voltage generator through a probe corresponding to the two ends of the open circuit fault, wherein the signal display is, for example, an oscilloscope. The voltage generator applies a non-zero voltage to the two ends of the loop sensing line, and determines whether the signal display shows zero voltage drop. When the signal display shows zero voltage drop, fills the conductive block in the open circuit break, and the signal display does not display zero. When the pressure drops, stop the next steps.

The signal display 24 is, for example, an oscilloscope. The voltage generator 26 applies a non-zero voltage to both ends of the loop sensing line 20 to determine the open circuit condition by using the display waveform of the signal display 24. When the display waveform is zero voltage drop, the loop sensing line 20 is in a non-open state. When the loop sensing line 20 is in a non-opening condition, the open circuit breaker 22 is further provided with a conductive block 28, such as silver, so that the conductive block 28 extends over the top surface of the loop sensing line 20 to utilize the conductive block 28 The loop sensing line 20 is electrically connected and forms an electrical closed loop with the loop sensing line 20.

The two ends of the line 20 are measured, and it is determined whether the signal display 24 displays a zero voltage drop. Since the loop sensing line 20 does not have any open circuit in this embodiment, the signal display 24 displays a zero voltage drop, and at the same time, as shown in FIG. 3(c), fills at least one conductive block 28 at the open circuit break. In the 22, the conductive block 28 is electrically connected to the loop sensing line 20 and forms an electrical closed loop with the loop sensing line 20.

The two ends of the line 20 are measured, and it is determined whether the signal display 24 displays a zero voltage drop. Since the loop sense line 20 has an unknown open circuit in this embodiment, the signal display 24 does not display a zero voltage drop and stops the subsequent steps.

The voltage generator 26 applies a non-zero voltage to the loop sensing line 20 corresponding to each of the open ends 22 to use the display waveform of the signal display 24 to determine the open circuit condition. When the display waveform of the signal display 24 is zero voltage drop, then It is indicated that the loop sensing line 20 is in a non-opening state. Therefore, each of the open faults 22 is further provided with a conductive block 28 made of silver, so that all the conductive blocks 28 extend over the top surface of the loop sensing line 20 to utilize all The conductive block 28 is electrically connected to the loop sensing line 20 and forms an electrical closed loop with the loop sensing line 20.
