Splicing Shims

SKU SS-3210-2 Category

SMD Splicing Shims are easy to use, you will need our Heavy Duty Tape Splicer Tool TS-41097.

Place splice tape with shim on the two center alignment pins on your Tape Splicer tool with the teeth on the splice shim pointing up. Ensure the Tape Splice Tool is in the open position. Place both sides of the carrier tapes on the alignment pins of the Tape Splice Tool and turn the hold downs to secure the carrier tape to the tool and crimp the Splicer tool.

SMT Splicing Shims (Brass and Stainless Steel)

SMT splicing shims are precision metal alignment components used during surface-mount carrier tape splicing to maintain sprocket hole continuity, pitch accuracy, and feeder engagement in accordance with ANSI/EIA-481-C.

These shims are placed at the splice joint to mechanically reinforce the connection between two carrier tape segments, ensuring uninterrupted component feeding during active or staged production.

Dimensional Specifications

  • Shim Width: 22 mm (0.86 inch)
  • Sprocket Pitch (Po): 4.00 mm
  • Sprocket Hole Diameter (Do): Ø1.50 mm
  • Hole Center Spacing: 0.00 mm – 3.50 mm center-to-center
  • Carrier Tape Standard: ANSI/EIA-481-C compliant

All dimensions are designed to align precisely with standard SMT carrier tape geometry and feeder sprocket requirements.

Material Construction

Brass Shims: Manufactured from precision-rolled brass alloy for dimensional stability, consistent hardness, and resistance to deformation under feeder tension. Brass provides predictable mechanical behavior and avoids variability associated with low-grade copper alloys.

Stainless Steel Shims: Manufactured from corrosion-resistant stainless steel for applications requiring increased wear resistance or extended reuse.

These shims are not copper foil and are not plated copper substitutes. Material selection is based on mechanical performance, not cost reduction.

Functional Purpose

SMT splicing shims serve to:

  • Maintain correct sprocket hole pitch across a splice
  • Prevent feeder skipping or loss of indexing
  • Reduce carrier tape distortion at the splice joint
  • Support high-speed placement without feeder interruption
  • Preserve alignment during reel changeover and tape handoff

They are used in conjunction with mechanical splice tools to ensure repeatable, controlled splices.

Installation Overview

  • Open the tape splicer tool to the alignment position
  • Place the splice tape with shim onto the two center alignment pins
  • Orient the shim with the teeth facing upward
  • Position both carrier tape ends onto the alignment pins
  • Engage the hold-down clamps to secure the carrier tape
  • Crimp the splicer tool to complete the splice

Correct alignment of the shim ensures sprocket pitch continuity through the splice area.

Compatible Splice Tool Requirement

SMT splicing shims are designed for use with heavy-duty mechanical tape splicer tools capable of controlled crimping and precise alignment. Proper tooling is required to achieve consistent results.

Available Part Configurations

  • SS-3210 – Standard Brass Shim-Clips (1000 pieces per box)
  • SS-8000 – Standard Stainless Steel Shim-Clips (1000 pieces per box)
  • SS-9000 – Short Stainless Steel Shim-Clips (1000 pieces per box)
  • RSS-1000 – Roll-Format Standard Brass Shim-Clips (1000 pieces per box)

Standards and References

  • ANSI/EIA-481-C — Carrier Tape, Reel, and Sprocket Hole Standards
  • SMT Feeder Sprocket Pitch: 4.00 mm
  • Industry-standard carrier tape geometry for automated placement systems

Common Misconceptions

  • SMT splicing shims are not adhesive substitutes
  • Brass shims are not interchangeable with copper foil
  • Material thickness, hardness, and hole accuracy directly affect feeder reliability
  • Improvised or soft metal inserts can cause feeder indexing errors

Summary

SMT splicing shims are precision mechanical components used to preserve carrier tape geometry at splice points. When manufactured from brass or stainless steel to ANSI/EIA-481-C dimensions, they provide reliable feeder engagement, consistent sprocket pitch, and uninterrupted component placement across reel transitions.

They are a functional necessity in controlled SMT splicing processes, not a consumable shortcut.
