Worried About Fake Chips? Here is How We Protect Our Clients

“How do I know these chips are actually original?” This is a question we hear often, especially from our international clients in Russia and Europe. Con “Low Copy” and refurbished chips circulating in the market, a standard visual inspection is no longer enough.

A Real Case from July 2026
We recently handled a project requiring the FM33LC023U MCU. Since the stock had to be sourced from the open market due to urgent lead times, Fuli Hong Electronics implemented a fail-safe quality protocol.

Paso 1: The Decap Test (El “Truth” Under the Microscope)
We sent samples from different batches for Chip Decapsulation. This involves removing the outer packaging of the chip to inspect the silicon die directly.

• Interesting Finding: We found internal structure differences! But instead of a fake, our investigation revealed a version upgrade—the 2025 model included a new ECC function not found in the 2020 version.

Paso 2: Supplier Accountability
We didn’t stop at the microscope. We demanded Quality Assurance letters from the suppliers and cross-verified the version history with Fudan Micro’s technical updates.

Paso 3: Sample Testing (The Final Barrier)
To give our client 100% tranquilidad de espíritu, we suggested a trial run:

1. Assembled 10pcs PCBA samples per batch.

2. Rigorous functional testing by the client.

3. Full production only after 100% pass rate.
