Recently, the “Chang’e-3” successfully landed on the moon, marking a significant milestone in China’s spaceflight history. The achievement of a flawless soft landing and mastery of key technologies has led many researchers to assert that Chang’e-3 surpasses the capabilities of both the US and the Soviet Union. Critics might argue about the forty to fifty years that have passed, questioning our advancement. However, our rapid progress and high success rates are sources of pride. Rather than dwelling on past achievements, true heroes compare them to contemporary aerospace advancements. Similarly, PCB reverse engineering technology, often underestimated and priced lower than branded counterparts, absorbs predecessors’ experiences to accumulate technological gains, transforming them into assets for further innovation and advancement.

The reasons for China’s delayed lunar exploration

Thousands of years ago, the Chinese wove a beautiful tale of Chang’e flying to the moon. Throughout history, our country has continuously pursued lunar exploration. However, due to technological backwardness, we initially lagged in mastering crucial technologies such as artificial satellites, manned spaceflight, and deep space exploration. We could only watch as countries like the Soviet Union, the United States, France, and Japan repeatedly led lunar missions. Observing their achievements highlighted our country’s first recognition of the space technology gap, prompting an influx of foreign technology through introduction and reverse engineering.

The Concept of PCB Copying and Its Auxiliary Characteristics

PCB copying is a form of reverse engineering technology. It involves extracting comprehensive technical data from existing electronic products and circuit boards—such as PCB files, BOM lists, and schematic diagrams—through reverse research methods. This data is then used to replicate, clone, or further innovate and develop technologies. However, PCB copying alone cannot achieve feats like landing on the moon, which currently only five countries have accomplished. Instead, it serves as a supplementary tool for developing countries to rapidly upgrade key technologies. True advancement requires independent research and innovative development.

Enhancing Chang’e-3’s Key Instrument Technology through PCB Copying

The auxiliary role of PCB copying is most evident in the instruments aboard Chang’e-3. These include soft landing detectors, patrol devices, astronomical telescopes, extreme ultraviolet cameras, range and speed radars, and laser rangefinders. These instruments have made significant contributions to aerospace history and other fields globally. Despite sharing names with their international counterparts, their performance and efficacy may differ. Through secondary development via PCB copying, these instruments have evolved into more advanced products, continuously improving PCB technology.

The Application of Aerospace Equipment PCB Copying in Civilian Applications

Some may perceive aerospace equipment as distant and irrelevant to daily life, believing PCB copying offers limited potential. This is a misconception. Consider the high-tech liquid rocket engines that propelled Chang’e on its lunar journey—they have been adapted for civilian use. For instance, the Sixth Research Institute of China Aerospace Science and Technology Corporation has employed aerospace technology to produce xylitol, used aerospace pumps for high-rise fire suppression, enhanced automotive safety, and controlled air pollution. These applications directly impact people’s lives. With intensified research and development, the PCB industry stands to achieve even greater innovations and benefits.
