PI labels are high-performance, heat-resistant identification materials based on polyimide (Polyimide), specifically designed for electronic manufacturing and industrial extreme environments. They can stably withstand high-temperature processes such as SMT reflow soldering and wave soldering.<br /> Their core performance advantages include:<br /> Excellent heat resistance: With a long-term operating temperature range of 260°C to 300°C, some special models can withstand ultra-high temperatures of up to 350°C or even 1200°C for short periods (e.g., the PL8520 series), making them suitable for multi-layer board multiple reflow processes.<br /> <br />
