Back Grinding Tape -P Series-
A back grinding tape (hereafter as BG tape) is used for protecting the circuit surface from scratches, chipping / crack and particle contamination, during the back-grinding　process. The functions of BG tapes are (1) protecting workpiece surface from contamination, (2) highly close contact to workpiece and (3) easiness of peeling, and higher technology to those functions is required with the developments of jumbo-sized and thinned wafer and high-bumped wafer. Elegrip BG tapes produced by DENKA do not require to rinse your workpiece after BG process due to excellent adhesive. We Toyo Adtec consider needs of each user and choose appropriate tapes.

Feature
Excellent contact to asperity of the circuit side
Effective control of particle
Good water-seepage control
Excellent grinding accuracy (TTV)
Easy peeling
Effective control on adhesive deterioration with time
