Masking Tape for Printed-circuit Board ELEP MASKING N-300

Tapes for masking terminals during plating of printed circuit boards.

ELEP masking tape N-300 is a surface protective material of polyester base material. The tape offers excellent chemical resistance and firm adhesion in masking terminals of printed-circuit board at the time of plating process, especially effective for preventing ingress of plating solution.



  • 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.
  • Withstands severe conditions and leaves almost no adhesive residue.
  • Adhesive strength hardly changes after application, and is easy to peel.

  • * Surface material: Stainless steel board


  • Ideal for preventing ingress of plating solution when plating printed-circuit boards.


  • 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.
