Strip Assembly & Lamination
What it is
Laminating the sample pad, conjugate pad, membrane and absorbent pad onto a backing card.
How it works
Pads are overlapped at controlled positions and laminated onto the card; correct overlap drives capillary flow.
Why it matters
Pad overlap and alignment determine capillary flow and reproducible results — misalignment causes flow failure.
Key components
- Backing card
- Pad overlap control
- Lamination inspection
Applications
- Laminating sample pad, conjugate pad, membrane and absorbent pad onto a backing card
What affects performance
- Pad overlap and alignment
- Lamination pressure
- Component positioning
Limitations
- Misalignment causes flow failure
- Overlap variation affects reproducibility
Common failure modes
- Pad misalignment causes flow failure
- Overlap error interrupts capillary flow
- Inconsistent lamination pressure
