It is not smartphones and autonomous vehicles that integrate electronic products into their daily lives. Even our one-off products, especially packaging, can be high-tech, and silicon-free printed electronics may become a future trend. Use prints to change product design and manufacturing. Printed electronics has repeatedly published news in the past year. They provide the electronics industry with something that has been used by semiconductor manufacturers in the past: fully customizable circuits with custom components. At present, typical circuit boards are produced as follows: First, design and print circuit boards. When the PCB is ready for installation, the parts are ordered from the distributor and placed on the PCB by hand or by machine. Once the part is in place, the PCB (with the component) is then sent to the final product (unless the PCB itself is the final product). If design changes are required during this process, the engineer may need to make some redesigns (sometimes the overall PCB), change the component list, and then change the entire production line to account for this change. The time it takes to make changes can cost the company's money and resources, with a typical PCB lead time of 7 days. These seven days were converted into seven days of discontinuation, so there was no sale for seven days.
