Masking Tape 3250A/3700 for Multilayer Board
DATE:2015-02-03【BIG MID SMALL】 TOP:

Masking tape protect various substrates in the multilayer substrate manufacturing process. Their weak adhesion characteristic permits easy peeling and improved workability.

Advantages

  • - The acrylic adhesive is coated onto the thin polyester film uniformly in the clean environment.
  • - Since the tapes can be peeled off easily thanks to weak adhesion, they will be a suitable solution to protect insulation and resist layers in the multilayer substrate manufacturing process.
  • - Thanks to excellent transparency, the tapes are suitable for various types of optical materials.
