โ“ Frequently Asked Questions
Q1 What is polyimide tape and why is it referred to as "Golden Finger Tape"?
Polyimide tape consists of a premium polyimide film coated with high-grade silicone or acrylic adhesive. It earned the name "Golden Finger Tape" because it is primarily used to shield the gold-plated contact fingers on printed circuit boards (PCBs) from molten solder and chemical erosion during wave soldering and surface treatment.
Q2 What is the continuous operational temperature rating of this polyimide tape series?
All models across our series are designed to withstand continuous high temperatures up to 260ยฐC (500ยฐF). This high thermal endurance ensures reliable performance during intense soldering, hot air leveling, and continuous oven-baking procedures.
Q3 Does the adhesive leave any sticky residue after thermal processing?
No. Our polyimide tapes feature specialized silicone adhesives that cleanly peel away from metal, composite, and glass substrates without leaving any sticky or chemical residue, eliminating the need for post-process solvent cleaning.
Q4 Which models serve as direct drop-in equivalents to 3M industrial tapes?
We offer standard drop-in replacements for benchmark 3M models: Model HY200-2B replaces 3M 98C-12, Model HY200-2D matches 3M 7413D, and Model HY200-2F is equivalent to 3M 98C-1, providing identical specifications with enhanced cost efficiency.
Q5 How does polyimide tape function within lithium batteries and electric vehicles (EV)?
In EV and lithium battery production, polyimide tape serves as critical insulation for battery tabs, module inter-cell barriers, and wire harnesses. It provides high chemical resistance against electrolytes, tolerates structural vibration, and prevents electrical leakage across high-voltage circuits.
Q6 Can custom widths, lengths, and die-cut shapes be manufactured?
Yes, comprehensive customization is available. We can tailor the film thickness (from 0.015mm to 0.125mm), total thickness, peel adhesion levels, overall roll widths, lengths, and supply precision die-cut adhesive shapes designed for automated application equipment.
