How to Identify Genuine and Fake IC Chips Instantly?
In IC procurement, the greatest concern for buyers is not the price, but product quality. The IC chips on the market vary greatly, and without careful attention, it can be hard to distinguish between them—whether they are genuine, refurbished, or counterfeit. Some companies sell refurbished, copy parts to customers and lie to them they are New&Original , earning huge profits but causing our customers/buyers significant losses, not only loss money, but also loss their precious customers. Fake components have become a growing issue in the supply chain, and it seems never die.
Below are key methods shared by experienced IC buyers on how to differentiate original chips from fake or refurbished ones.
Step 1, Appearance and Size Similarities
Counterfeit chips can look almost identical to genuine ones. This often happens when authorized suppliers cannot provide parts, forcing buyers to rely on third-party distributors. These chips can include original, refurbished, and even faulty ones.
In some regions, people collect electronic waste, refurbish the components, and resell them in the market. These operations contribute to the availability of counterfeit and refurbished components.
Step 2, Types of Counterfeiting
– **Refurbished Chips**: These are typically old chips with bent pins that are cleaned up and repackaged to look new.
– **Re-marked Chips**: Chips are reprinted with new labels, making them appear as a higher-grade product (e.g., industrial-grade chips relabeled as military-grade).
– **Sophisticated Counterfeits**: Some counterfeiters may go as far as repackaging the chips entirely, making it very difficult to differentiate from the original.
Step 3, How to Identify Fake Chips
- **Surface Grinding Marks**: If a chip has been ground down to remove old markings, it will have fine lines or traces of the previous marking. Some counterfeit chips may have a layer of coating applied to hide these signs.
- **Printed Labels**: Genuine chips have clear, well-aligned text that is difficult to erase. Counterfeit chips may have jagged or blurry text, unevenly printed, or may use old methods like silk-screening, which leave slight texture differences on the surface.
3. **Pins and Leads**: Authentic IC leads have a uniform appearance, usually dull and consistent. Refurbished chips often have excessively shiny leads, indicating they have been re-soldered or re-plated.
4. **Production Date and Packaging Markings**: The marking on the chip should match the production timeline and packaging. Discrepancies, such as mixed date codes or suspicious marking patterns, are red flags.
5. **Thickness and Edges**: Chips that have been ground down to remove original markings will often be slightly thinner. Additionally, the edges of genuine chips tend to be rounded from the molding process, while ground-down chips may have sharper edges.
Step 4, Tips for Identifying Refurbished Chips
– **Check the Label**: Use a solvent like thinner to check if the printed markings can be wiped off.
– **Inspect the Leads**: Authentic leads are perfectly aligned and straight. Refurbished ones may have bent or uneven leads.
– **Examine the Reference Hole**: Genuine chips often have consistent reference holes. In refurbished chips, these may be ground down or altered.
By carefully inspecting these features, buyers can better protect themselves from the growing issue of counterfeit chips, ensuring they receive quality components for their products.
