Flexible printed electronics is a new technology industry. Its representative products, such as FPC, are widely used in 5g communication, Internet of things, automotive electronics, wearable devices, intelligent packaging, biomedical and many other industries. In people's daily life, mobile phones, computers, bracelets, cars, fabrics, packaging and so on are inseparable from flexible printed circuit products. With the miniaturization, curved surface and flexibility of electronic products, the traditional flexible printed circuit based on copper foil corrosion also faces many technical challenges and bottlenecks. The manufacturing technology of industrial liquid metal electronic additive has brought new changes to the industry
