Services: Anti-counterfeit Management


Anit Counterfiet

The semiconductor market is plagued with technology cloning, re-branding and mis-labeling of substandard or defective electronic components to imitate higher-qualification EEE parts. The re-marking is done on salvaged parts from scrapped assemblies or even stolen parts. Some parts are manufactured illegally from original molds and designs. The inherent hazards of such practices result in use of in-correct die, inferior product, packages without die, false ROHS classifications, etc.


Types of Counterfeit Electronic Components

Any available components re-coded to customer order

Reclaimed components for correct device type sold as new

Components re-coded to a higher grade part

Test failures from factory via unauthorized routes

New lower grade components remarked



 

Major Impacts

May not meet manufacturer’s specification

Poor yields when built into system

Latent ESD damage from poor handling, uncertain reliability

Mixed lots, lack of traceability

Potential negative impact on user’s reputation



Why is Counterfeiting so rampant?

Shorter product lifetimes

Obsolete components difficult to source

Current components on long lead times disrupt production

Buyers’ pressure to reduce cost of materials

Ready supply of reclaimed components from electronic scrap

Obsolete/high reliability grade parts command a higher price



How Si360™ can add value?

Si360™ has an overriding commitment to test for counterfeit devices and ensure unquestionable quality products to our customers. We have extensive knowledge of original manufacturers’ test protocols that facilitates us in detecting any suspect products or foul play.
