Double-Sided PET white film flexible circuit board flexible circuit board has been mass-produced, which has become a key breakthrough for smart wearable devices to meet the requirements of lightness and thinness. With lighter weight, thinner thickness and better flexibility, this technology solves the problem that traditional circuit boards are difficult to adapt to miniaturized equipment. Its mass production capacity will accelerate the upgrade of smart wearable products to lightweight and comfortable.
The core advantage of double-sided PET white-film flexible circuit boards is the dual optimization of materials and structures. PET white film substrate itself has good insulation and flexibility. Compared with traditional rigid circuit boards, the weight is reduced by about 30%, and the thickness can be controlled within 0.1 mm. It can fit the wrist, neck and other human curves to reduce the feeling of foreign body when wearing. At the same time, the double-sided circuit design improves the space utilization rate, realizes more functional integration within the limited equipment volume, and reserves more design space for sensors, endurance modules and other components.
Previously, double-sided PET white film flexible circuit boards were in the small batch trial production stage for a long time due to the complexity of the production process and the difficulty of controlling the good quality rate. With the improvement of laser cutting accuracy and the maturity of automated welding technology, the good product rate of mainstream production enterprises has been stabilized at more than 95%, and the single-day production capacity can reach tens of thousands of pieces, and the large-scale supply capacity has been basically formed. This change not only reduces unit production costs, but also enables manufacturers of smart wearable devices to make production plans more flexibly.
The lightness and thinning of smart wearable devices is not simply an improvement in appearance, but a core requirement for upgrading user experience. The lighter and thinner body means longer battery life, more comfortable wearing experience, and richer appearance design possibilities. The mass production of double-sided PET white film flexible circuit boards just provides technical support for this trend, so that manufacturers do not need to compromise between function and volume when designing bracelets, watches, smart glasses and other products.
GuangDong KungXiang New Material Group Co., Ltd. is an important participant in it. The company focuses on the research and development and production of flexible electronic materials, and has accumulated a number of technical patents in PET substrate modification, circuit pattern etching and other fields. Its double-sided PET white film products have passed many head intelligent wearable equipment factories. The certification of merchants is gradually becoming a key part of the industry supply chain.
