3M Greenback Printed Circuit Board Tape 851 Green, 1/4 in x 72 yds x4.0 mil

Key points

• 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
• Specially designed adhesive that generally performs better when no ovens are used to heat tape and boards
• Polyethylene tape core instead of cardboard
