SMT Leader Tape Extenders Tapesplice
FUNSMT leader tape extenders rescue partial reels and short strips missing the factory leader. Each extender adds a standardized 396 mm PET leader that bonds permanently to cover tape with high-tack adhesive — no more sacrificing 10–20 components per reel to reach the feeder's pick point. Available in 8–24 mm widths (custom to 88 mm), 500 pieces per box.
Optimize your component utilization with Funsmt’s high-precision Cover Tape Extenders. Designed specifically for partial reels and short strips where the factory leader is missing, these extenders eliminate component waste and drastically reduce feeder loading time, ensuring a seamless start to your production run.
Key Benefits for High-Yield Assembly
-
Eliminate Component Scrap: By providing a standardized 396mm leader, you no longer need to sacrifice the first 10-20 components of a reel to reach the feeder’s pick-up point.
-
Reduce Feeder Load Time: The non-skid PET material is engineered for rapid threading, allowing operators to load short reels into the feeder as easily as a full roll.
-
Universal Sizing: Available in standard widths (8mm, 12mm, 16mm, 24mm) to match all common carrier tapes, with custom widths up to 88mm available upon request.
-
Industrial Strength Bond: Features a high-tack adhesive that creates a permanent, secure bond with the original cover tape, ensuring it won't peel or snap under the tension of high-speed feeders.

Frequently Asked Questions
When do I need a leader tape extender?
Whenever a reel or strip lacks a factory leader — partial reels, cut tape, or sample strips. Without a leader the feeder cannot thread, and operators waste components reaching the pick point.
How do I attach it?
Peel the release liner, align the extender's front edge with the carrier tape's leading edge, press the adhesive strip firmly onto the cover tape, then feed the non-adhesive PET leader into the feeder. No tools required.
What sizes are available?
8 mm (396 × 5 mm), 12 mm (396 × 6 mm), 16 mm (396 × 9 mm): 500 pieces per box; 24 mm (396 × 16 mm): 250 pieces per box. 508 mm lengths and 32–88 mm widths are available on request.
Does it work on both paper and embossed carrier tapes?
Yes. The high-tack adhesive bonds to standard cover tapes on both paper and embossed plastic carriers, and the anti-static PET leader threads smoothly through the feeder.
What is the MOQ and lead time?
There is no rigid MOQ — we support trial orders as well as volume repeats. Standard sizes ship from our U.S. warehouse (San Jose, CA) in 2–3 business days; custom specifications are made to order.
