Description
Flextac Tape Dots are a wire tacking system consisting of pre-cut shapes of a thin, flexible polymer film membrane coated on one side with a high performance, electronics grade permanent pressure sensitive adhesive resulting in a highly conformable, high strength bond. The adhesive release liner is an environmentally stable poly-coated kraft.

As with any wire tacking material, in order to achieve maximum bond strength and reliability, application surface must be clean, dry and free of flux, skin oils and other contaminants. Clean with isopropyl alcohol or equivalent if necessary. Firm application pressure develops better adhesive contact and thus improves bond strength. Avoid placing Flextac Tape Dots or any other wire tacking material directly over exposed copper or plated surfaces.

Flextac Tape Dots will perform best when applied at temperatures between 15°C and 38°C. Do not apply below 10°C.

• Bond Strength
  Flextac Tape Dots have very good initial bond strength that generally increases as a function of time over approximately 72 hours to stabilise as a high strength reliable bond.
• Humidity Resistance
  High humidity has a minimal effect on adhesive performance. Bond strengths are actually slightly higher after exposure for 7 days at 32°C and 90% relative humidity.
• Temperature Cycling and Bond Strength
  Bond strength generally increases after four times through:
      4 hours at 70°C
      4 hours at -29°C
      16 hours at room temperature.
• Cleaning Process Resistance (chemical & hot water)
  Tape Dots will hold securely after exposure to numerous chemicals including most flux cleaning solutions/sprays, saponifiers, "Freon" TF, mild acids and alkalis. Wires will hold securely through a typical pcb hot water wash.
• Temperature Range
  Low: -40°C
  High short term: 200°C
  High long term: 135°C.
• Repositioning
  Flextac Tape dots can be repositioned during and immediately after initial bonding without causing adhesive transfer or loss of bond strength.
• Shelf Life
  Product retains its performance and properties for one year from date of purchase if properly stored at room temperature conditions. Storage in plastic bag is recommended.
