この切断用途が使用される工程
Semiconductor fabrication production
DBG Process Dicing Tape is processed by razor slitting 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 razor presentation, penetration depth, web tension, support and slit-line alignment.
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.

ナイフ交換前に確認すべき問題
The cut edge shows adhesive transfer, backing stretch, liner cut-through, edge lift or particulate contamination
Compare blade condition, razor presentation, penetration depth, web tension, support and slit-line alignment, 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.
検討可能なナイフ形状
| 候補となるナイフ形状 | 検討できる条件 | 確認が必要な事項 |
|---|---|---|
| Precision razor slitting blade | Considered when razor slitting requires clean narrow-web edges without adhesive drag or surface marking under stable support and guidance. | Confirm only after reviewing a real DBG process dicing tape sample, the equipment interface, mounting drawing, operating direction and an accepted cut reference. |
| Low-drag web slitting blade | Considered when the equipment interface and material response require an alternative geometry or cutting motion. | Confirm only after reviewing a real DBG process dicing tape sample, the equipment interface, mounting drawing, operating direction and an accepted cut reference. |

- DBG Process Dicing Tape composition, grade, thickness and allowable lot variation
- Layer, coating, porosity, temper, adhesive or surface-function details relevant to razor slitting
- Input width and target dimensions, tolerances and acceptance drawing
- Line speed, feed mode, tension or hold-down, temperature and cutting frequency
- Current blade or knife drawing, holder interface, mounting dimensions and used sample
- Material direction, support, contact faces and product or waste collection method
- Accepted and rejected samples with limits for cut width, edge cleanliness, adhesive residue, liner condition, particle level and dimensional stability
- Trial quantity, inspection method, downstream operation, packing and annual demand
この切断用途に関するよくある質問
Why must DBG process dicing 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 razor slitting performance.
Can the blade be selected from the material name alone?
No. Confirm razor presentation, penetration depth, web tension, support and slit-line alignment, the holder interface, production speed, support and accepted samples before fixing the blade geometry.
What commonly causes defects during razor slitting?
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 DBG process dicing tape lot, setup, speed, support, blade condition, dimensions, edge observations, waste behavior and downstream acceptance.
