In the era of the full-scale explosion of Industry 4.0 and Internet of Things (iot) devices, reliable communication at the kilometer level and the ability to survive in electromagnetic extreme environments have become the core lifeblood of industrial automation systems. Renesas' RS-232/RS-485/422 interface chips, with ±30kV ESD protection, 0.1μA ultra-low power consumption and military-grade reliability, have built the "steel and iron backbone" of industrial communication networks. Facing the inventory backlog caused by technological iteration and capacity adjustment, Shenzhen Mingjiada Electronics Co., Ltd. has launched a special high-price recycling service for the entire Renesas interface chip series - with nanosecond-level signal detection, dynamic value assessment and 72-hour global payment collection, it helps enterprises activate tens of millions of silent assets and reshape the green cycle of the industrial communication ecosystem.
The key categories that Mingjiada focuses on recycling
Multi-protocol RS-485/422 and RS-232
A device integrating RS-232 and RS-485 transceivers into a single package
2. RS-232 serial interface
Transceivers with a data rate of up to 1Mbps, ESD protection, and low-power turn-off mode
3. RS-485/RS-422
Half-duplex and full-duplex transceivers of various rate grades
Ii. Mingjiada Recycling System: From Signal Integrity Verification to Global Premium
1. Military-grade inspection process
Wafer traceability verification: X-ray scanning is compared with Renesas wafer batch codes, and open cap analysis (Decap) is used to verify the 0.35μm BCD process structure.
Full-temperature range performance test: Verify the baud rate error (< ±0.2%) in a -55℃ to 150℃ incubator, and detect the eye pattern opening degree at a rate of 10Mbps using a dedicated carrier plate.
Extreme pressure challenge: ±60V short-circuit withstand test lasts for 1 hour, with the failure rate returning to zero.
2. Dynamic Value assessment model
Based on the global industrial equipment maintenance database:
New energy shortage model: ISL3152EIBZ, which supports ±30kV ESD, has a premium rate of 35% due to the maintenance and repair requirements of photovoltaic inverters.
Long-life industrial model: ISL32435EIBZ, which can withstand a temperature of 125℃, has a 28% premium.
Packaging status bonus: Unrolled tape material (original factory vacuum packaging + desiccant) will be charged an additional 8%.
3. ESG compliance regeneration
Chip-level rebirth: Devices that pass the 1000-hour aging test enter the industrial aftermarket;
Green Metallurgy Revolution: Anaerobic pyrolysis of failed chips to recover gold/palladium, reducing carbon emissions by 85%.
Three and four-step rapid monetization: Global funds arrive within 5 days
Encrypted list submission: model (e.g. ISL3152EIBZ)/quantity/package photo sent to sales@hkmjd.com, get pre-price in 20 minutes;
Safe delivery: Delivery at the inspection centers in Shenzhen/Munich/Houston, or DHL anti-static armor box with global cash on delivery.
Payment upon inspection: Full payment will be made by telegraphic transfer within 24 hours of arrival. Offshore RMB settlement is supported.
