High Temperature Polyimide Tape for Gold Finger Masking | 260℃ Wave Soldering - STK
High Temperature Polyimide Tape – Silicone Adhesive 0.08mm is the backbone of the printed circuit board assembly (PCBA) process. Specifically designed for wave soldering environments, this high temperature polyimide tape protects sensitive gold contacts from solder splash, flux contamination, and chemical exposure during PCB manufacturing.
At STK, we understand that reliability is non-negotiable in electronics manufacturing. Our 0.08mm single-sided polyimide tape features a high-performance silicone adhesive system that maintains dimensional stability and adhesion performance at temperatures up to 260°C. The polyimide backing ensures excellent electrical insulation, zero shrinkage under heat, and clean residue-free removal after processing.
Widely trusted by Tier-1 EMS manufacturers, this tape is ideal for high-volume PCB masking, SMT processing, gold finger protection, lithium battery insulation, and precision electronic assembly applications where stable high-temperature performance is critical.
