Performance characteristics of touch screen failure - Weiluntong

The parameters of the touch screen to characterize the characteristics of the capacitor include the loss factor D value, the figure of merit Q, the series equivalent resistance ESR, etc., the essence is the same, take a parameter to know the quality of the capacitor, but take the loss factor D value reference meaning. These parameters can usually be tested with a digital bridge to show that the withstand voltage performance of the capacitor is reduced, and the withstand voltage value can be tested using a transistor tester.

Causing the interaction to appear too slow. 1.3 Window-oriented point-and-click interfaceThis kind of interface is also known as WIMP interface, that is, the window (Windows), icons (Icons), menu (Menus), and indicator (PointingDevice) are four-in-one to form the desktop (Desktop). This method can display different kinds of information at the same time, so that users can switch between several work environments without losing the connection between several jobs, users can easily perform control and conversational tasks through drop-down menus, and the introduction of icons, buttons and scroll stick technology greatly reduces keyboard input, which undoubtedly improves the interaction efficiency for users who are not good at typing. 1.4 Natural language uses natural language to communicate with application software, combining third-generation interface technology with hypertext, multi-tasking concepts, so that users can perform multiple tasks at the same time (from the user's point of view). With the further development of text, graphics, and speech recognition and infusion technology. In addition, the person engaged in the preservation work has a unified understanding of the organization and the important thing about the organization of the maintenance of machinery and equipment, and it is important to have a unified understanding of whether the main body of preservation or the improvement of the preservation is to be the main body of preventive preservation or to reduce failures on the basis of efforts to eliminate, and the purpose of mechanical preservation is that the basic equipment of equipment preservation refers to the general term of the material means that constitute the system as an element of capacity in order to provide production activities and services.

When a component fails, analysts must utilize a variety of processes, tools, and techniques to determine why the equipment is failing and how to prevent future failures. PCB Failure Mode AnalysisThe following processes present unique challenges for electronic device failure analysis: increased density, higher lead-free process temperature requirements, hazardous material recycling requirements, PCB tuning to value, other relevant changes in PCB manufacturing, root cause analysis, and the fabrication of complete PCB assemblies requires a range of machines and materials. For example: Screen Printing MachinesConveyor Pick & Place SystemsReflow OvensAutomated Optical Inspection of Solder Paste Different ComponentsSome machines have automatic features that can perform inspections at various points, and the operator performs a visual inspection before, during, or immediately after completing the task. However, many PCBs will fail the final test. When this happens, it's important to perform an effective electronic device failure analysis to get clear and accurate details about the source of the problem and ensure that it doesn't happen in the future.
