OVERVIEW
Polyimide Circuit Board labels are specially designed identification labels for printed circuit boards (PCBs) and electronic components. They maintain stable performance in high-temperature, chemically corrosive, and mechanically stressful environments, ensuring reliable traceability throughout the entire manufacturing process and product lifecycle..
Feature：
High-Temperature Resistance
Withstands 260°C–320°C during reflow soldering and wave soldering processes without warping, carbonization, or delamination.
Short-term exposure tolerance to 150°C+ ambient temperatures (e.g., automotive engine compartments).
Material Compatibility
Application:
Electronics Manufacturing
PCB Assembly: Labels withstand reflow soldering (260°C+) and wave soldering, ensuring legibility throughout SMT processes.
Component Tracking: Identifies ICs, resistors, and connectors on boards during production and testing.
Optimal Printing Solutions
Recommended Ribbons:
GAOFE TR4510B resin ribbon
High Temperature Resistance
Withstands 300°C for 10 seconds (compatible with reflow/wave soldering processes)
Short-term exposure tolerance up to 150°C (e.g., automotive ECU modules)
Recommended Printers:
Zebra ZT610 Industrial Printer
Supports 600dpi ultra-high resolution printing
Delivers crisp reproduction of 0.2mm micro fonts/barcodes
Ideal for precision PCB labeling and tiny component identification
