Walk down any SMT or final-assembly line and you will find adhesive tape at almost every station — masking gold fingers before reflow, grounding shields, bonding nameplates, protecting displays. Because each station has different temperature, electrical, and residue requirements, no single tape covers them all. Procurement teams that standardize a short, qualified tape list avoid two common failures: a tape that chars or leaves residue in a 260°C reflow oven, and an unqualified film that generates static near sensitive components. The nine categories below cover the large majority of tape consumption on a typical electronics line.
1. Polyimide (Kapton-type) tape for reflow and wave-solder masking. Polyimide tape with silicone adhesive is the default for masking gold fingers, connectors, and plated through-holes during soldering. The polyimide film typically withstands roughly 260–300°C — above lead-free reflow peaks — and silicone adhesive is chosen specifically for clean, residue-free removal after the thermal cycle. For a deeper look at how long polyimide survives at each temperature band, see our guide to Kapton tape temperature ratings.
2. ESD / anti-static grid tape for static-safe zones. Inside an EPA (ESD-protected area), ordinary packing tape is a liability because peeling it generates triboelectric charge. ESD tape — often a printed-grid PE or PET film with low-charging adhesive — is used to seal bags, secure work-in-process, and mark static-safe boundaries without spiking charge near MOSFETs, drivers, and other sensitive devices. Lines usually pair it with anti-static tape for sealing moisture-barrier bags after baking.
3. Copper foil tape for EMI shielding and grounding. Copper foil tape with conductive adhesive provides quick grounding paths, cable shielding, and gap closure on enclosures and flex assemblies. It solders easily for permanent ground straps. Where weight or cost matters more than solderability, aluminum foil tape or fabric-based EMI shielding tape serves the same shielding role.
4. Thermal interface tape for heatsinks and LED modules. Thermally conductive heat transfer tape bonds heatsinks to chips, LED strips to aluminum channels, and power components to chassis without screws or liquid compounds. It is essentially a filled acrylic adhesive that conducts heat across the joint; for thicker gaps or uneven surfaces, a thermal pad or fiberglass thermal tape is the better fit. Verify the thickness and gap-filling need before specifying.
5. Double-sided tape for mounting and laminating. Lines use several formats of double-sided tape: thin PET-carrier tape for dimensionally stable bonds on nameplates and lenses, economical tissue tape for gaskets and foams, and carrier-free transfer tape for laminating membranes and graphic overlays. For heavier loads — bonding frames, bezels, or battery packs — high-strength acrylic foam tape absorbs stress and resists aging far better than thin films.
6. Protective film for displays and finished surfaces. Self-adhesive PE protective film guards displays, lenses, and brushed-metal housings from scratches during assembly, test, and shipping, then peels cleanly at the customer end. Where higher clarity or temperature resistance is needed — for example films that stay on through a curing step — PET protective film is the upgrade, since PET tolerates roughly 120–220°C versus PE's much lower limit.
7. Mylar tape for coil, harness, and battery wrapping. Mylar (PET film) tape is the standard outer wrap for transformers, inductors, wire harnesses, and lithium battery cells. The PET film offers good dielectric strength, puncture resistance, and a service range typically around 120–220°C depending on grade — well matched to motor and coil insulation classes.
8. Electrical insulation tape for terminations and barriers. General-purpose insulation tape isolates terminals, busbars, and crossing conductors. PVC-based tapes are economical but limited to roughly 60–80°C, so anywhere near heat-generating components, lines step up to PET, polyimide, or PTFE-glass constructions (PTFE-glass handles around 260°C). Choosing by actual operating temperature — not just dielectric rating — is the most common correction we see; our article on choosing high-temperature tape walks through the decision.
9. Polyimide label stock for traceability through reflow. Barcode and 2D-code labels that travel through reflow must survive the same 260°C peaks as the solder paste. Polyimide label material — the same film family as high-temperature tape — keeps printed traceability data legible after multiple thermal cycles, where paper or standard PET labels would darken or curl. Pre-cut label blanks are a typical die-cutting job, converted to the exact footprint of the PCB fiducial-safe zone.
Three checks prevent most field problems. First, match the adhesive chemistry to the job: silicone for high-temperature stations with clean removal, acrylic for permanent bonds needing UV and aging resistance, rubber for high initial tack at room or low temperature — the trade-offs are detailed in acrylic vs rubber adhesive. Second, request peel adhesion data measured to ASTM D3330 so quotes from different suppliers are comparable, and confirm values as typical ranges rather than single guaranteed numbers. Third, for any tape that stays in the finished product, require current RoHS and REACH documentation, since electronics customers in the EU and North America will audit the bill of materials down to the adhesive layer.
HONGFU manufactures all nine categories on this checklist — from polyimide and ESD tapes to copper foil, double-sided, and thermal products — in factory-direct jumbo rolls, slit rolls, or die-cut parts with RoHS/REACH documentation. Consolidating the list with one supplier simplifies qualification and logistics; send your station-by-station requirements through our inquiry page for samples and datasheets.
Polyimide tape with silicone adhesive is the industry standard. The polyimide film withstands roughly 260–300°C — above lead-free reflow peaks — and the silicone adhesive removes cleanly without residue on contacts after the thermal cycle.
No. Peeling standard tape generates triboelectric charge that can damage sensitive components. Use ESD grid tape or anti-static tape with low-charging adhesive for sealing bags and securing work-in-process inside an EPA.
Both shield effectively, but copper foil tape with conductive adhesive can be soldered, making it better for permanent ground straps and terminations. Aluminum foil tape is lighter and lower-cost where solderability is not required.
Ask for peel adhesion measured to ASTM D3330 on the same substrate (typically stainless steel). This standardized method makes datasheet values comparable. Treat published figures as typical ranges, not guaranteed minimums, and confirm with samples on your actual surface.
Process-only tapes such as reflow masking carry lower risk, but any tape remaining in the finished product — mounting, insulation, wrapping, labels — should have current RoHS and REACH documentation, since EU and North American customers audit adhesive layers in the BOM.
