Waar deze snijtoepassing voorkomt
Semiconductor fabrication production
Leadframe Dambar Removal Tape is processed by kiss cutting to support wafer mounting, dicing, molding protection and temporary process support. The finished geometry must remain compatible with downstream handling and assembly.
Cut-quality control
Production teams compare accepted and rejected samples for cut width, edge cleanliness, adhesive residue, liner condition, particle level and dimensional stability, then relate the result to penetration depth, liner thickness, support pressure, registration and release behavior.
Stable material and waste handling
clean contact surfaces, controlled web tension and protected collection of converted tape help the product and waste leave the cut zone consistently without creating a second defect after separation.

Problemen die vóór een meswissel moeten worden onderzocht
The cut edge shows adhesive transfer, backing stretch, liner cut-through, edge lift or particulate contamination
Compare blade condition, penetration depth, liner thickness, support pressure, registration and release behavior, material lot and accepted versus rejected samples.
Finished dimensions drift during a production run
Check feed registration, tension or hold-down, temperature, support condition, runout and when dimensions are measured.
The workpiece shifts, curls or loses functional surface quality
Review clean contact surfaces, controlled web tension and protected collection of converted tape, contact-face cleanliness, material direction, support and the first point where deformation appears.
Product and waste do not separate consistently
Check cut completeness, waste width, exit angle, static, extraction, collection tension and downstream transfer.
Mogelijke mesvormen
| Mogelijke mesvorm | Wanneer deze kan worden overwogen | Wat moet worden bevestigd |
|---|---|---|
| Rotary kiss-cutting blade | Considered when kiss cutting requires complete part separation without unwanted liner cut-through under stable support and guidance. | Confirm only after reviewing a real leadframe dambar removal tape sample, the equipment interface, mounting drawing, operating direction and an accepted cut reference. |
| Flatbed kiss-cutting rule | Considered when the equipment interface and material response require an alternative geometry or cutting motion. | Confirm only after reviewing a real leadframe dambar removal tape sample, the equipment interface, mounting drawing, operating direction and an accepted cut reference. |

Vragen over deze snijtoepassing
Why must leadframe dambar removal tape be reviewed as a complete material construction?
Its substrate, coating, interfaces and surface condition can respond differently to pressure, friction and bending, so nominal thickness alone does not predict kiss cutting performance.
Can the blade be selected from the material name alone?
No. Confirm penetration depth, liner thickness, support pressure, registration and release behavior, the holder interface, production speed, support and accepted samples before fixing the blade geometry.
What commonly causes defects during kiss cutting?
Material variation, unstable support, alignment error, contamination, inappropriate clearance and blade wear can interact to create adhesive transfer, backing stretch, liner cut-through, edge lift or particulate contamination.
When should the finished dimensions be measured?
Record both immediate and conditioned results when recovery, residual stress, temperature, moisture or adhesive flow can change the part after cutting.
What should be recorded during a production trial?
Record the leadframe dambar removal tape lot, setup, speed, support, blade condition, dimensions, edge observations, waste behavior and downstream acceptance.
