Masking Tape for Printed Circuit Board N-380
Tapes that protect printed circuit boards from spray and hot vapors of plating solution during plating of printed circuit boards.
Outline
ELEP masking tape N-380 is a polyvinyl chloride-based surface protective material for masking printed-circuit boards. With its excellent chemical resistance and firm adhesion, the tape is suitable for preventing contamination of the circuit board by splashes and/or vapor of the plating solution.
Structure
- Easy to unwind and easy to apply.
- The special adhesive agent makes the tape firmly adhere to the printed-circuit board and does not peel or dislocate during work.
- Exhibits even higher adhesiveness by pressing with heating roller.
- Excellent in chemical resistance.
- The tape does not peel or dislocate when it overlaps with one another because it does not use any silicone reverse-side treatment.
- Adhesive strength hardly changes after application, and is easy to peel.
Application
- Masking of printed-circuit boards to prevent contamination by splashes and vapors of plating solution.
Typical properties
| Product name | Thickness[mm]*1 | Adhesive strength[N/20mm]*2 |
|---|---|---|
| N-380 | 0.080 | 1.00 |
- [Test method]
- *1 Nominal thickness
- *2 Conforms to JIS Z-0237 standards (Surface material: Stainless steel board, Peeling speed: 300mm/min, Peeling angle: 180°)
Precautions
- Avoid sunlight and store at room temperature and moderate humidity.
- Do not press too strong when applying. This may cause the end of the tape to peel.
- If applying to surfaces treated with machining oil, degrease the surface carefully. Any remains will be a cause for surface contamination or adhesive residue.
- For use under severe conditions, please test and evaluate the product thoroughly beforehand.
- Painting, plating, etching, or gluing the surface after peeling the tape may be troublesome due to the small amount of residue of the adhesive. Please inspect under actual situations thoroughly before application.
- Painted boards, depending on conditions such as paint baking, may cause the tape to peel uneasily or peel off the paint together. Please evaluate thoroughly beforehand.
- Surface treated boards such as alumite, depending on treatment conditions, may show different properties (peeling) of SPV. Please evaluate thoroughly beforehand.
- Especially for applications against natural substrate (marble stone, lumber, ｅｔｃ) please contact our sales representative in charge.
