(I) PCBA in Industrial All-in-One Touch Screens
The PCBA production workshop environment is a testing ground for equipment durability and stability. Dust, welding fumes, static electricity, vibration, oil contamination, and other adverse factors constantly test the equipment. In such an environment, ordinary commercial display devices are often vulnerable and may struggle to last even a single shift. However, industrial all-in-one touch screens stand out as an ideal choice, thanks in large part to the PCBA.
Interference resistance is the cornerstone of stable equipment operation in the workshop. During PCBA production, high-frequency current disturbances around wave soldering and reflow equipment generate frequent electromagnetic interference. If the screen experiences false touches or freezes due to interference, not only is operation affected, but troubleshooting can be time-consuming. The PCBA in industrial all-in-one touch screens typically utilizes an EMC (Electromagnetic Compatibility) design. The G2 industrial all-in-one touch screen has been deeply optimized in this regard, ensuring smooth operation even in environments with strong electrical interference. This has been proven in numerous high-precision workshops. When workshop workers directly touch the screen, their hands may carry solder flux or metal debris. Ordinary screens that aren't scratch-resistant will quickly become covered in scratches, compromising their usability. The PCBAs used in industrial control all-in-one touch screens utilize high-strength glass panels that are resistant to dirt and wear. The Kongxian G2 industrial control all-in-one touch screen also supports water-stain touch and oil-film protection, ensuring normal clicking and selection even with foreign matter on hands.
Considering the compact workstations and limited space in workshops, equipment installation demands higher standards. Industrial control all-in-one touch screen manufacturers have carefully considered their structural design, and their PCBAs support various mounting options, including embedded, wall-mounted, and VESA brackets. Kongxian industrial control all-in-one touch screens are highly favored in PCBA line upgrade projects due to their compatibility with various mounting methods.
(II) Industrial control PCBAs for driving high-power motors
In the field of industrial automation, industrial control PCBAs play an irreplaceable and critical role in devices that drive high-power motors. Take a common industrial robot as an example. Its robotic arm needs to perform complex movements such as precise grasping, handling, and welding, requiring an industrial control PCB (PCBA) to accurately process motion control commands. Equipped with a high-performance microcontroller and dedicated motion control chip, it can quickly interpret host computer commands and convert them into precise motor drive signals, enabling real-time, accurate control of each joint in the robotic arm.
High-power motors generate significant heat during operation. Poor heat dissipation can cause localized overheating, leading to component failure or even system failure. Therefore, heat dissipation design is a critical aspect of industrial control PCBs. Copper foil, the primary thermal conductive material in PCBs, has a significant impact on heat transfer efficiency. In high-power motor drive circuits, the wiring of the main circuit and power components (such as MOSFETs and IGBTs) typically utilizes 2oz or 3oz thick copper foil to reduce electrical and thermal resistance, while also increasing the copper foil area of the power and ground layers, improving overall heat transfer efficiency.
Thermal vias are also a core structure for PCB thermal management. Densely placing thermal vias beneath heat-generating areas quickly conducts heat from the top layer to the bottom layer or heat sink, reducing junction temperature. Optimizing parameters such as aperture diameter, spacing, and copper plating thickness is crucial. For example, increasing aperture diameter and the number of vias can improve Z-axis thermal conductivity, but be careful not to oversize the apertures, which can compromise thermal conductivity uniformity in the X and Y directions. Ensure that the copper plating thickness of the via walls is consistent with the surface copper foil. During layout, densely arrange thermal vias beneath high-power components to form a "thermal via array," but avoid excessive vias near critical signal lines to prevent electromagnetic interference and reduce mechanical strength.
Thermal simulation techniques (such as finite element analysis (FEA)) are valuable tools for PCBA thermal design, predicting hotspot distribution and optimizing design parameters. By constructing a 3D thermal model and incorporating boundary conditions such as copper foil thickness, via density, and ambient temperature, the junction temperature (TJ) and temperature differential distribution of different design solutions can be compared to verify that they meet thermal resistance requirements. In actual testing, an infrared thermal imager is used to monitor the processed PCBA in real time to locate hot spots. The simulation model is then reverse-corrected based on the test data, forming a closed loop of "design-simulation-testing-optimization" to ensure stable operation of the PCBA under complex working conditions.
