280°C Double-Sided Polyimide ESD Tape: Dual-Adhesive Anti-Static Protection for Advanced Electronics Assembly
280°C Double-Sided Polyimide ESD Tape: Dual-Adhesive Anti-Static Protection for Advanced Electronics Assembly
Dual-coated polyimide film with balanced anti-static matrix on both silicone PSA layers. Prevents electrostatic discharge (ESD) catastrophic failure during automated tape unwind, placement, and peak temperature reflow.

In modern surface-mount technology (SMT) lines, microprocessors and MOSFET arrays are vulnerable to latent ESD defects. Standard non-ESD double-sided Kapton tapes generate static charges exceeding 1,500 Volts during liner peeling and high-speed unwind operations. When combined with infrared or forced-convection reflow ovens operating at 260°C–280°C, ordinary adhesives degrade, leaving silicon residue or causing substrate shifting due to thermal expansion mismatch.
HuiLink’s Double-Sided Polyimide ESD Tape integrates a conductive nano-matrix directly into both pressure-sensitive silicone adhesive (PSA) layers and the central 25µm/50µm polyimide substrate. This structure ensures continuous charge dissipation throughout high-temperature processing steps.
Dual Anti-Static Layers
Both top and bottom adhesive surfaces maintain 10^6–10^9 Ω/sq surface resistance, capping triboelectric generation under 50V during peel.
280°C Thermal Stability
Retains shear strength and dimensional stability during lead-free SAC305 reflow profiles with peak exposures up to 280°C (536°F).
Zero Residue Clean Peel
Specially cross-linked silicone adhesive leaves no siloxane or organic contamination on copper fingers, gold contacts, or ceramic carriers.
Technical Specifications & Performance Metrics
Engineered for high-reliability military, automotive electronics, and semiconductor packaging applications, our tape meets strict industry requirements:
| Performance Characteristic | Test Method / Standard | HuiLink ESD Double-Sided Spec |
|---|---|---|
| Total Thickness (Excluding Liner) | Micrometer Standard | 0.09mm - 0.16mm (Customizable) |
| Carrier Film Thickness | ASTM D3652 | 25µm / 50µm Polyimide Film |
| Surface Resistivity (Both Sides) | ASTM D257 / ESD S11.11 | 10^6 - 10^9 Ω/sq |
| Static Decay Rate | FTMS 101C (5000V to 50V) | < 0.01 Seconds |
| Max Continuous Temperature | Thermal Cycling Test | 260°C (500°F) |
| Peak Short-Term Temperature | Reflow Simulation (10 min) | 280°C (536°F) |
| 180° Peel Adhesion (To Steel) | ASTM D3330 | 5.0 - 7.5 N/25mm (Balanced Dual-Side) |
| Release Liner Type | Visual / Thickness | Fluorosilicone Coated PET Film (50µm) |
When mounting flexible circuits (FPC) onto rigid stiffeners or carrier plates prior to reflow, ensure pressure is applied uniformly across the release liner with a rubber roller. This eliminates micro-air pockets and optimizes initial tack before entering the pre-heating zone.

1. Flexible Printed Circuit (FPC) SMT Mounting
During SMT component placement on flexible circuits, FPCs must remain perfectly flat on rigid aluminum or graphite carrier trays. HuiLink double-sided ESD polyimide tape securely holds thin FPC boards through high-velocity solder reflow zones without lifting, curling, or generating static charges during de-taping.
2. EV Battery Module Thermal & Electrical Insulation
In electric vehicle battery cell assembly, double-sided polyimide ESD tape acts as a high-dielectric barrier between prismatic or pouch cells. It bonds thermal pads to aluminum cooling plates while providing ESD protection and thermal resistance up to 280°C.
3. BGA Reballing & Component Shielding
Used for temporary grounding and positioning of Ball Grid Array (BGA) components and delicate IC chips during thermal rework, ensuring adjacent solder joints remain undisturbed by stray thermal radiation or static voltage spikes.
