Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Under the wave of the deep integration of edge computing and AIoT technology, ROHM's Solist-AI™ series of microcontrollers, with their ultra-low power consumption and real-time inference capabilities, have become the core engine for industrial Internet of Things, smart sensors and wearable devices. However, the accelerated technological iteration has led to a large number of unused or discontinued AI chips piling up in factory warehouses. Shenzhen Mingjiada Electronics Co., LTD., a leading enterprise with 20 years of experience in the field of electronic component recycling, is providing efficient recycling services for Solist-AI™ microcontrollers to the industrial chain with its professional technical assessment system and global recycling network, promoting the recycling and regeneration of cutting-edge chip resources.

The nerve endings of Edge Intelligence: The core value of Solist-AI™ microcontrollers

The ROHM Solist-AI™ series is specifically designed for edge AI tasks. Its heterogeneous computing architecture integrates an Arm Cortex-M core with a dedicated neural processing unit (NPU), enabling real-time inference tasks such as image recognition and sound classification at microwatt-level power consumption. This type of chip is widely used in:

Industrial predictive maintenance system: Real-time analysis of equipment status through vibration sensors to avoid unplanned downtime.

Medical wearable devices: Real-time processing of electrocardiogram signals and abnormal early warning to ensure the reliability of health monitoring.

Intelligent agricultural sensors: Field image recognition of pests and diseases, reducing cloud transmission delay and energy consumption.

Such scenarios have extremely high requirements for the environmental tolerance and long-term supply stability of chips. Production line adjustments, design changes or order cancellations often result in the original factory-sealed Solist-AI™ chips becoming idle inventory. If they cannot be circulated in time, these high-end chips will depreciate rapidly with technological iterations.

2. Mingjiada Solist-AI™ Recycling Solution: Four-dimensional Professional System

Precise Assessment: Cracking the Value Code of AI Chips

The recycling value of Solist-AI™ needs to be determined from multiple dimensions, including the process technology, NPU computing power level and packaging compatibility. The Mingjiada technical team has passed:

In-situ testing: Use dedicated fixtures to verify the inference energy efficiency ratio and memory integrity of the chip;

Batch traceability: Verify the original factory labels, sealing conditions and temperature and humidity storage records;

Market benchmarking: Refer to the current computing power demand gap of edge AI chips (such as the shortage of chips in the 2-4 TOPS computing power range);

Ensure that each chip receives a scientific valuation to prevent high-quality assets from being undervalued.

High-price recovery strategy: Activate the liquidity of idle assets

For the Solist-AI™ feature, Mingjiada adopts a dynamic pricing model:

The premium rate of the automotive-grade version (operating range: -40°C to 125°C) reaches 65% to 80% of the market price in circulation.

Original packaging chips with complete Reel reels have an additional 15% higher recycling value.

Global recycling network: 72-hour rapid response

With the Shenzhen Bonded Warehouse hub and the Hong Kong International Logistics Center, Mingjiada has achieved:

Asia-pacific region: Door-to-door pickup within 24 hours (covering customers in Japan, South Korea and Southeast Asia)

In Europe and America: The chips are transshipped and cleared through Hong Kong, and are inspected in the warehouse within 72 hours

Compliant delivery: Full ESD protection and temperature-controlled transportation to ensure zero static damage to the chips.

Compliance transaction guarantee: Building a trusted ecosystem

Mingjiada strictly limits the sources of recycled goods to:

Unopened and slow-moving inventory of the original factory's agent

The remaining materials of the EOL project in the terminal factory

Spare parts of discontinued models from certified distributors

Prevent the inflow of refurbished materials and substandard products from the source to maintain the reliability of the circular industrial chain.

3. Why Choose Mingjiada: Three Advanced Values Beyond Traditional Recycling

Precise pricing, with a premium as high as 30%

Dynamic value anchoring: Based on the demands of application scenarios such as automotive-grade (like AEC-Q100) and industrial-grade, rare models are priced at a floating increase according to the gap in the terminal market, with a premium range of 5% to 10%.

2. Quantum-level quality inspection, eliminating risks

Triple verification system

X-ray scanning of the internal structure eliminates the risk of refurbishment/counterfeiting.

The electrical performance test verifies the withstand voltage/current parameters (such as -55℃ to 150℃ incubator cycle).

Verify the original factory code and package integrity to ensure that the package has not been powered on or opened.

3. Global network, funds arrive instantly

24-hour response: After submitting the model/quantity/batch, the quotation will be completed within 1 working day (preliminary review of pictures is supported).

48-hour payment collection: Full payment will be remitted by telegraphic transfer after inspection. Settlement is supported in US dollars, euros or RMB, with no delay in payment.

Cross-border worry-free: Inspection centers are set up in 10 countries including Japan, the United States, and Hungary, taking on the risks of customs clearance and logistics losses.

Mingjiada Electronics has upgraded the recycling of Solist-AI™ microcontrollers from traditional asset disposal to a springboard for technological iteration through its dedicated AI chip assessment platform and carbon equity swap program.
