BenteIC | IC Back-end Finishing Process Optimization
Release time:2026-05-22
Most domestic IC post-processing factories adopt factory default parameters and manual debugging, resulting in unstable tolerance, uncalibrated temperature zones and non-traceable data.
Common industry defects include batch yield fluctuation, solder ball falling off, soldering offset and hidden failure after temperature cycling.
Bente Semiconductor focuses on quantifiable process optimization and equipment calibration rather than marketing concepts. All technical upgrades are data-verified.
1. Full-process Closed-loop Error Control
Industry Defect
Multi-factory outsourcing causes cumulative alignment error ±0.03–0.08mm, leading to poor batch consistency.
Technical Optimization
Unified mechanical calibration origin for all machines; cancel external outsourcing; build exclusive parameter compensation database for each batch.
Final Effect
Cumulative process error controlled within ±0.01mm.
2. 4-stage Stepwise Reflow Temperature Algorithm
Industry Defect
Single temperature curve causes ball crack, cold solder and internal stress, with defect rate 0.8%–2%.
Technical Optimization
Self-developed four-stage heating & cooling curve; temperature accuracy upgraded from ±3℃ to ±1℃; independent threshold for 0.3mm–0.76mm ball size.
Final Effect
BGA soldering defect rate reduced to ≤0.08%.
3. Quantitative Pressure Sensing Ball Mounting System
Industry Defect
Manual pressure adjustment leads to pad damage and unstable offset, highly dependent on worker experience.
Technical Optimization
Install high-precision pressure sensor; build 5-level quantitative pressure database (0.01N fine-tuning); automatic pressure calibration before production.
Final Effect
Alignment offset＜0.005mm, zero pad damage, fully reproducible process.
4. Fixed Timing Lock & 5-level Reliability Testing
Industry Defect
Unlocked programming timing causes code loss and verification error; single inspection cannot detect hidden aging failure.
Technical Optimization
Timing data full lock; implement initial test + real-time verification + full inspection + aging retest + batch data traceability.
Final Effect
Zero programming error, terminal customer product return rate reduced by over 90%.
Technical Summary
Bente’s core advantage lies in digital, quantifiable and standardized process transformation.
We turn traditional empirical processing into precise, calibrated and replicable industrial manufacturing, solving mass production instability fundamentally.
