Sierra Electronics Leadertape Extenders give new life to partial reels with no usable leader, allowing your SMT feeder to pick the very first component at the correct pick position. Made in the USA using premium DuPont-grade adhesives, each extender provides a strong, stable cover layer that bonds cleanly to your existing carrier tape.

These extenders are compatible with all major pick-and-place platforms and deliver consistent indexing, smooth feeder engagement, and faster setup on short reels, re-runs, or high-mix production. Ideal for eliminating scrap starts, feeder mispicks, and downtime from leader-less reels.

“Pick from component one, every time.”

Chinese imports lack indicator lines, use inconsistent adhesive coating, and often misplace the adhesive zone—resulting in partial adhesion that fails under tension. Sierra’s precise application line guarantees full adhesive contact and exact placement every time.

Why Covertape Extenders Are Essential

Many partial reels arrive:

■ Without a leader ■ With too short of a leader ■ With damaged or torn cover tape ■ Without a leader, the operator must sacrifice 10–50 components just to load the reel. Sierra’s Leadertape Extenders eliminate this ■ waste by giving operators a perfect leader instantly, making every reel ready for immediate placement.
