3M 851 Polyester Printed Circuit Board Masking Tape

3M 851 Polyester Printed Circuit Board Masking Tape

  • Low-stretch polyester film can be applied by machine or by hand
  • Polyester backing reduces stretch and recovery of tape associated with uneven stop-off line
  • Thick adhesive coating reduces undercutting because adhesive blocks out solutions between fingers
