Dicing and Backgrinding Tapes
Loadpoint offer a variety of dicing tapes sourced from leading manufacturers to suit a variety of applications.
Tapes include but are not limited to; low cost general purpose blue tape, semiconductor grade tape, UV tapes & backing tapes.
General purpose blue tape dicing tape
The low tack & low/medium comprise of a PVC base with a non-UV acrylic adhesive and are suitable for general purpose wafer dicing where UV applications are not required.
Available in either Low tack or low medium tack.
Available widths include but not limited to: 150mm, 180mm, 195mm, 200mm, 230mm, 270mm, 280mm & 300mm.

Applied directly to the back of the substrate to create additional dicing depth & rigidity.
Combining our blue dicing tape and green layering tape can also help minimise component movement during dicing
The green layering tape comprises of a Polyester base with a non-UV Silicone adhesive and is used for dicing glass and ceramic substrates. The tape is applied directly to the backface of the substrate, in one or two layers, to provide extra tape thickness to avoid the effects of blade wear. Layering tape is used in conjunction with blue non UV tapes and provides a good alternative to wax mounting.
UV dicing tape
Available in multiple sizes & variety, dependent on required application. Suitable for a variety of materials where high adhesion is required with minimal adhesive residue.
