Maker Studio | Iron Man Based on Flexible PCB

1. We are members of the Maker Studio at Zhengzhou University of Light Industry, dedicated to a diverse range of cutting-edge research and development. Our areas of expertise span medical devices, soft robotics, five-axis CNC machine tool equipment, 3D printing technology, artificial intelligence, robotics, big data analysis, the Internet of Things, and new energy sources.
2. As avid fans of Marvel superheroes, we have long harbored a creative dream—to create a project themed around Iron Man. After careful consideration, we decided in March of this year to turn this dream into reality by developing a luminous Iron Man core device. Throughout the innovative design process, we proposed a variety of fresh ideas and ultimately chose to use flexible PCB boards for our design. This material selection not only reduces the weight of the device but also makes it thinner, perfectly reflecting our pursuit of innovation and practicality.
3. 我们是郑州轻工业大学梅科尔工作室的团队成员，专注于一系列前沿技术的研究与开发。我们的研究领域广泛，涵盖了医疗器械、软体机器人、五轴数控机床、3D打印技术、人工智能、机器人技术、大数据分析、物联网以及新能源等多个方面。
4. 身为漫威超级英雄的忠实粉丝，我们一直怀揣着一个创意梦想——打造一个钢铁侠主题的项目。经过深思熟虑，我们在今年三月决定将这一梦想付诸实践，着手制作一款发光的钢铁侠核心装置。在创新设计的过程中，我们提出了多种新颖的想法，并最终选择了使用柔性PCB板来实现这一设计。这种材料的选择不仅减轻了装置的重量，也使其更加轻薄，完美地体现了我们对创新与实用性的追求。

Step 1: We Use Fusion Electronic to Draw the PCB Board

1. Fusion Electronic software is very user-friendly, especially the feature that allows the three-dimensional dimensions of the PCB to be directly aligned with the actual object, which is very convenient. We use it to draw the schematic diagrams and complete the PCB routing. Then we export the routing diagram as a PDF and print it on thermal transfer paper.
2. Fusion电子软件非常用户友好，特别是可以直接将PCB的三维尺寸与实际物体对齐的功能，非常方便。我们用它来绘制原理图并完成PCB布线。然后我们将布线图导出为PDF，并打印在热转印纸上。

Step 2: Heat Transfer Printing Process

1. Cut out the circuit part from the heat transfer paper, use polyimide tape (orange) to adhere the inked area of the circuit to the copper foil, and then place it on the hot plate (with the copper foil on the bottom and the circuit lines of the heat transfer paper facing the copper foil). At a temperature of 200°C, roll over the tape several times to ensure that the ink is fully transferred onto the copper foil (as shown in the figure).
2. 将热转印纸电路部分裁剪下来，用聚酰亚胺胶带（橙色的）将电路带有油墨的地方与铜箔粘到一起，贴到恒温台上（铜箔在下方，热转印纸有电路线的地方朝向铜箔），在200℃的温度下，用胶带碾压几遍使墨迹充分转印到铜箔上（如图）

Step 3: PET Substrate Fabrication

1. Remove the polyimide tape to reveal the copper foil, and check if the circuit has been fully transferred (look for any broken lines, shallow ink, or overly fine ink traces). If the transfer is insufficient, use an oil-based marker to repair it, ensuring the circuit is functional.
2. 撕去聚酰亚胺胶带，得到铜箔，查看电路是否转印充分（有无断线、墨迹过浅、墨迹过细等情况），不充分需要用油性记号笔修补。

Step 4: Etching Copper Foil

1. First, prepare the etching solution by mixing 60ml of water with 15g of etching powder and stirring until dissolved. Then, immerse the circuit in the etching solution and place it on a hot plate to use the residual heat for heating during the etching process. Finally, after etching is complete, remove the circuit and rinse it several times in clean water to remove any etching solution residue from the flexible board. Use a cotton swab dipped in carbon powder cleaner to apply it to the blackened circuit areas, repeating the process several times to clean the circuit. With this, the fabrication of the flexible PCB board is complete.
2. 首先是配置蚀刻溶液，一般量为60ml水+15g蚀刻粉，搅拌溶解；然后将将电路置于蚀刻液中进行蚀刻，放在恒温台上用余热加热；最后，取出蚀刻好的电路，在清水中涮洗几次洗去柔性板上附着的蚀刻液，使用棉签蘸取碳粉清洗剂涂抹在电路黑炭上，多涂抹几次，得到电路，柔性pcb板制作完成。
