1. Concern: Chip performance degradation & latent damage caused by ESD or overheating
Solution: Full ESD protection with constant temperature & humidity workshop. Strict reflow profile to avoid thermal damage. 100% electrical retest to restore original chip performance.
2. Concern: Low yield, missing balls, offset balls & solder bridging
Solution: High-precision CCD positioning (±25μm) with stencil & vacuum fixture. First-pass yield ≥99.5%. AOI & 3D X-Ray full inspection, void rate ≤3%. Stable production for 0.25mm ultra-fine pitch.
3. Concern: Weak solder joints, ball dropping & excessive voids leading to failure
Solution: Adopt high-purity solder balls and dedicated flux. Vacuum reflow soldering, void rate strictly controlled below 3%. Batch pull & shear strength tests for reliable solder joints.
4. Concern: Long lead time, refusal of small orders & no rush support
Solution: Specialized in small-batch production & rapid sampling. Standard delivery in 3-5 days, urgent orders finished within 24-48 hours. Accept orders starting from 1 piece with flexible capacity.
5. Concern: Unclear pricing & hidden charges
Solution: All-inclusive transparent quotation covering ball mounting, cleaning and testing. No setup fee or rework charge for defects on our side. Volume discount for bulk orders.
6. Concern: Non-standard processes & no traceability for after-sales issues
Solution: Standardized SOP for all workflows. Unique ID for full lifecycle traceability. Complete records of equipment parameters, reflow curves and test data available for review.
7. Concern: Inability to process high-density, ultra-thin & special-shaped chips
Solution: Professional in BGA with pitch from 0.25mm to 0.5mm. Support ultra-thin chips, LGA to BGA conversion and special alloy soldering. Custom precision fixtures & laser alignment, sampling prior to mass production.
8. Concern: Secondary damage during rework
Solution: Low-temperature desoldering to protect pads. Local heating with nitrogen protection for rework. 100% post-rework testing to ensure consistent quality.
9. Concern: Incomplete inspection leading to defective products delivery
Solution: Three-level inspection: AOI visual check, 3D X-Ray void & bridging detection, full electrical test. Defects fully intercepted with official test reports delivered together with goods.
10. Concern: Unstable supplier, insufficient technical capability & poor after-sales service
Solution: Brand system of BenteIC & Bentech Precision. Experienced technical team with factory-grade expertise. Upgraded equipment & continuous technical optimization. 7×24-hour after-sales support, response within 1 hour and problem resolution within 24 hours.
