Double-sided tissue tape for electronics is a lightweight bonding solution consisting of acrylic adhesive on a tissue carrier that provides dimensional stability. Designed for high-conformance bonding of flexible printed circuits (FPC), battery packs, and plastic housings, it provides peel adhesion up to ≥14 N/25mm and continuous thermal stability up to 160°C. Naikos manufactures high-precision tissue tapes that deliver stable shear strength across low-surface-energy (LSE) substrates and thin-profile electronic assemblies.
Failure Modes in Electronics Bonding: Why Tape Selection Matters
In electronic manufacturing services (EMS), adhesive failure leads directly to structural detachment, display lifting, or component displacement during thermal cycling. Common production line failures stem from three mechanical breakdown points:
- Low Initial Tack (Ball Test Failure): Insufficient wet-out on LSE plastics like polypropylene (PP) or polycarbonate (PC) leads to immediate lifting post-assembly.
- Adhesive Migration & Outgassing: Uncured acrylic monomers off-gas inside sealed enclosures, fogging optical sensors or degrading sensitive circuitry.
- Shear Creep under Thermal Stress: Standard pressure-sensitive adhesives soften above 60°C, causing sub-assemblies to slip under constant tension or battery swelling forces.
Correct selection of the carrier matrix and coat weight eliminates these yield losses at the SMT and final assembly stages.
Chemical Architecture: Carrier Matrix and Acrylic Formulations
The structural core of double-sided tissue tape relies on long-fiber tissue paper. Unlike rigid PET film carriers, tissue absorbs liquid adhesive during coating, yielding high flexibility and zero memory effect. This allows the tape to conform around curved battery wells and narrow bezel contours.

Frequently Asked Questions
Q: Are Naikos double-sided tissue tapes compliant with RoHS and REACH standards?
A: Yes. All Naikos tissue tapes undergo annual testing via third-party labs (SGS/TÜV). They comply strictly with EU RoHS 2011/65/EU and REACH SVHC requirements, certifying zero lead, cadmium, halogenized flame retardants, or restricted phthalates.
Q: What die-cutting tolerances can Naikos achieve for custom electronic gaskets?
A: Using high-speed rotary die-cutting and optical registration systems, Naikos maintains tight manufacturing tolerances of ±0.1 mm for custom shapes, pull tabs, and kiss-cut rolls on extended-release liners.
Q: Does Naikos provide free sample rolls for laboratory testing and prototyping?
A: Yes. We supply free sample rolls or die-cut prototype sheets for engineering evaluation. Standard sample shipments ship within 48 hours with full TDS and CoA documentation included.
