Product Features
- Temperature - up to 170°F /76°C
- 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
- Tape must be firmly pressed down by equipment with rubber-covered rollers or a rubber-covered platen press. Hand rolling usually does not provide enough pressure. A vivid outline of the circuit leads usually indicates adequate pressure was used
