SantacLB Sheet│

The adhesive layer of Santac LB sheet is Special Elastomer.
The elastomer melts with heat generated from Laser absorption spot(printing mask),and gives the excellent characterization.

Features

  • High-bond Strength
    Hot melt adhesion performs strong bonding
    LB sheet is about twice the bond strength of standard tapes
  • Easy Rework
    It is possible to rework easily by re-irradiating laser to bonding area.
  • Impact Resistance
    Elastomer adhesive layer absorbs the drop impact.
  • Water-proof
    Elastomer adhesive layer applied with laser covers the bumpy surfacesand prevents water from coming in.

Application

  • Bonding panel to housing(Adds narrow bezel and water proof)
  • Bonding battery to housing and pull-rework
  • Bonding BLU to LCD
