KPT-1 Kapton™ Alternative Polyimide Tape | 2.6 mil | 36 YD | Gold/Amber | Case

KPT-1 Wave Solder / Hot Air Leveling Tape — Case Pricing

A 1 mil electrical-grade Kapton™ alternative polyimide film coated with a high-performance silicone adhesive. Engineered for wave soldering and hot air leveling (HAL) processes, this tape delivers reliable masking, minimal residue, and clear visibility during board processing.

Key Features

• Thin and conformable — conforms tightly to PCB surfaces and gold contacts
• Adhesive thermosets under heat to increase bond strength during processing
• Leaves minimal residue after removal — reduces cleanup time and rejects
• Transparent gold/amber film allows visual inspection during processing
• Protects gold contacts from molten solder during HAL process
• Outstanding tear and abrasion resistance at elevated temperatures
• Excellent resistance to acids, oils, solvents, water, aging, and staining
