^{聚酯薄膜膠帶 851 電鍍遮蔽膠帶  高性能抗電鍍}

3M Circuit Plating Tape 851 is a Greenback Printed Circuit Board Tape ( polyester film) with a unique conformable adhesive for printed circuit board masking during electroplating.

• 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.

• For masking printed circuit boards during solder stripping and precious metal plating of fingers.
• Splicing of silicone coated papers.
