When electronic equipment always breaks down, this paper analyzes how to repair industrial touch screen today:
1. Observation method. As the name implies, it is used to visually check whether the components are burnt out, damaged, deformed, discolored and broken, and whether the filament of the picture tube shines after the current is connected. These problems are often faults or closely related faults. If you find these problems, you can quickly find out what is wrong and repair the industrial touch screen.
2. Knocking method. This is also one of the effective methods to repair industrial touch screens, especially for faults caused by poor contact. The method is: with or without power supply, tap and press the parts that are likely to have problems, so that faults such as virtual welding and poor contact can be easily found.
3. Replacement method. Replacement method is a practical and fast maintenance method. When you are not sure which parts, you can replace them with good ones first. If the fault is eliminated, it proves that there is something wrong with the original parts. Especially for some inconvenient measuring elements.
4. Current measurement method. Measuring current is one of the basic methods to repair industrial touch screen. It is mainly used to measure the load current and working current of transistors and integrated circuit blocks to detect whether the load of integrated circuits, transistors and their power supplies is normal or not. As long as the measured load current of the transistor or integrated circuit is normal, it can be concluded that the working state of the circuit is basically normal. On the other hand, if the current changes greatly compared with the normal value, it means that there is something wrong with the circuit, so you can prescribe the right medicine and focus on inspection. ..
Remarks on industrial touch screen products:
1. The film surface of the touch screen is the touch surface, that is, the front of the product;
2.The glass surface is a non-touch surface, that is, the back of the product.The touch screen is made of glass with sharp corners. Please wear gloves/finger covers when assembling.
3. The industrial touch screen is made of fragile glass, so do not have a strong impact on the touch screen during assembly.
4.avoid directly taking the lead in picking up the touch screen industry, and lead to avoid pulling the action site.
5. The outgoing steel plate shall not be bent.
6. Don't fold any part of the lead in half.
7. In the assembly process, the outlet line should be inserted horizontally, and it is not allowed to insert half at the root of the stiffening rib.
8. A single product used for handling, gently, to avoid product collision and scratch the surface.9. When cleaning the product surface, please wipe it with a soft cloth (deerskin) dipped in petroleum ether.10. Do not use corrosive organic solvents to clean the surface of industrial touch screens. Such as industrial alcohol.
