SMT Splice Tape Selection Guide

Definition

SMT splice tape is a precision consumable used to join the tail end of an expiring component reel to the leader of a new reel, allowing uninterrupted component feeding during active surface-mount assembly.

Purpose of Splice Tape Selection

Selecting the correct splice tape is a mechanical decision, not a branding choice. The splice must preserve pitch accuracy, tape rigidity, feeder tension, and placement stability throughout reel transition.

Primary Selection Variables

  • Component mass (passive vs active devices)
  • Tape pitch and width
  • Placement speed (CPH)
  • Feeder generation and wear
  • Carrier tape material
  • Production mode (prototype, NPI, high-volume)

Common SMT Splice Tape Categories

  • Standard double-sided SMT splice tape
  • Reinforced splice tape with metal shims
  • Pre-aligned splice tape with pins
  • Shim clip splice tape systems
  • Tool-assisted vs tool-free splice formats

Operational Impact

Incorrect splice tape selection increases:

  • Feeder mis-pick events
  • Component skew during handoff
  • Line stoppages during reel change
  • Feeder wear caused by thickness inconsistency

Proper selection supports continuous placement, stable handoff, and feeder longevity.
