U.S.-Manufactured SMT Splice Tape · High-Tension Covertape · Aerospace-Certified Adhesive Systems
Premium Adhesives from: 3M · Saint-Gobain · Nitto Tested and Certified in Santa Fe, New Mexico – USAQuality Control Overview – U.S. Aerospace & SMT Adhesive Validation

Sierra Electronics operates the most rigorous SMT splice tape quality control program in the United States, engineered for
high-reliability SMT production, 0201 micro-component assembly, aerospace PCB manufacturing, and defense-grade feeder tension requirements.
Unlike foreign importers and repackagers, Sierra physically tests every incoming adhesive master roll from 3M, Saint-Gobain, and Nitto
before converting it into:
- SMT splice tape
- Covertape extenders
- Covertape connectors
- Flat punched carrier tape leaders
- USA-made SMT splice kits
- Leaderless reel recovery products
This documented, high-precision QC workflow is something imported Chinese splice tapes cannot match. Sierra is a true U.S. manufacturer, not an importer.
Quality Control Overview – U.S. Aerospace & SMT Adhesive Validation
Sierra Electronics operates the most rigorous SMT splice tape quality control program in the United States, engineered for
high-reliability SMT production, 0201 micro-component assembly, aerospace PCB manufacturing, and defense-grade feeder tension requirements.
Unlike foreign importers and repackagers, Sierra physically tests every incoming adhesive master roll from 3M, Saint-Gobain, and Nitto
before converting it into:
- SMT splice tape
- Covertape extenders
- Covertape connectors
- Flat punched carrier tape leaders
- USA-made SMT splice kits
- Leaderless reel recovery products
1. Peel-Force Testing (Adhesion Strength Verification)
Every incoming roll undergoes full peel-force dynamometer testing, validating:
- Initial tack consistency
- Peel strength (gf/cm and oz/in)
- Shear resistance
- Release-liner uniformity
- Aging, dwell, and tension behavior
Materials failing Sierra’s tight aerospace-grade adhesive tolerance bands are rejected immediately.
2. Static-Load Holding Power Test (24-Hour & Weekend Hold)
Sierra simulates real SMT production tension using calibrated stainless-steel weights and vertical fixtures.
Tests replicate:
- 24-hour continuous SMT feeder tension
- Friday-to-Monday extended weekend holds
- Panasonic/NPM, Fuji, Siemens, Samsung high-tension feeder paths
- Partial-reel feeding with covertape extenders
- Long dwell times on dense pocket carrier tape
This ensures zero Monday-morning failures.
3. Extreme Tension Simulation (High-Speed SMT Feeder Stress Test)
Adhesive samples are subjected to multi-hour cyclic tension simulating:
- High-speed pick-and-place indexing
- Reverse feed cycles
- Emergency stop/start tension spikes
- Deep-pocket 0201/0402 carrier tape advancement
- Heavy stainless SMT reel operation
Only adhesives passing Sierra’s high-cycle fatigue requirements are accepted.
4. Sierra Weekend Hold Certification (Exclusive Test)

This Sierra-only method simulates:
- SMT line setup late Friday
- Reel loaded with Sierra Covertape Extenders, Sierra Covertape Connectors, and Sierra Splice Tape
- Full feeder tension sustained until Monday morning
This test exposes adhesive creep, cold-flow, delamination, liner memory failure, and bond fatigue, none of which are screened by importers.
5. Batch Traceability & QC Logging
Every roll receives:
- Sierra batch ID
- Supplier lot correlation
- Complete adhesive performance profile
- Peel-force curves
- Holding-power durations
- Shear displacement data
- Inspector verification
Nothing enters production without a full QC release.
