FAQ
Technical Selection What are the recommended tape solutions for wafer backgrinding, PCB wave soldering, and lithium battery insulation?
We manufacture precision industrial tapes engineered specifically for cleanroom silicon processing, high-temperature SMT assembly, and EV power battery cell packaging:
| Application Scenario | Recommended Tape Specification | Core Performance Parameters |
|---|---|---|
| 1. Wafer Backgrinding & Dicing | UV-Release Dicing Tape / PO Backgrinding Tape | High initial adhesion during mechanical grinding; UV-curing mechanism reduces peel strength to zero for residue-free, chip-free wafer pickup. |
| 2. PCB Wave Soldering Masking | Amber Polyimide (Kapton) Tape (HL-2550 Series) | 260°C – 300°C extreme heat resistance with silicone adhesive. Protects gold fingers and SMT components without adhesive ghosting or residue. |
| 3. EV Lithium Battery Insulation | Flame-Retardant PET / Polyimide Battery Tape | UL94 V-0 fire rating, high breakdown voltage (>6kV), solvent resistance against electrolyte immersion for pouch and prismatic cell wrapping. |

Custom Die-Cutting & ESD Do you offer custom precision die-cut shapes and Anti-Static (ESD) options?
Precision Die-Cutting & ESD Control: Yes. All polyimide tape and Polyester tape electronics tapes can be supplied with ESD-treated backing or anti-static adhesive (surface resistivity 10^6 – 10^9 Ω) to prevent electrostatic discharge damage to sensitive IC chips. We provide custom die-cut dots, rings, and complex geometric shapes with clear polyester liners for automated pick-and-place packaging lines.
